- A bunch of cleanup and removal of platform data for TI/OMAP platforms,
moving over to genpd for power/reset control (yay!)
- Major cleanup of Samsung S3C24xx and S3C64xx platforms, moving them

The CSC API (Colorspace conversion) allows userspace to try
to configure the colorspace, transfer function, Y'CbCr/HSV encoding
and the quantization for capture devices. This patch adds support
to the CSC API in vivid.
Using the CSC API, userspace is allowed to do the following:
- Set the colorspace.
- Set the xfer_func.
- Set the ycbcr_enc function for YUV formats.
- Set the hsv_enc function for HSV formats
- Set the quantization for YUV and RGB formats.

The patch partially reverts some of the UAPI bits of the buffer
cache management hints. Namely, the queue consistency (memory
coherency) user-space hint because, as it turned out, the kernel
implementation of this feature was misusing DMA_ATTR_NON_CONSISTENT.
The patch reverts both kernel and user space parts: removes the
DMA consistency attr functions, rolls back changes to v4l2_requestbuffers,
v4l2_create_buffers structures and corresponding UAPI functions
(plus compat32 layer) and cleans up the documentation.

The v4l2_async_notifier_add_subdev() function requires the asd pointer
it receives to be allocated dynamically, but doesn't explicitly say so.
Only one driver out of 13 get its right (atmel-sama5d2-isc.c, but with
memory leaks in the error paths), clearly showing we have an issue.
Update the v4l2_async_notifier_add_subdev() documentation to clearly
state the allocation requirement. Whether this will be enough to avoid
new offending code isn't certain, but it's a good first step
nonetheless.

rc-core kapi uses nanoseconds for infrared durations for receiving, and
microseconds for sending. The uapi already uses microseconds for both,
so this patch does not change the uapi.
Infrared durations do not need nanosecond resolution. IR protocols do not
have durations shorter than about 100 microseconds. Some IR hardware offers
250 microseconds resolution, which is sufficient for most protocols.
Better hardware has 50 microsecond resolution and is enough for every
protocol I am aware off.
Unify on microseconds everywhere. This simplifies the code since less
conversion between microseconds and nanoseconds needs to be done.
This affects:
- rx_resolution member of struct rc_dev
- timeout member of struct rc_dev
- duration member in struct ir_raw_event

Applications are expected to fill V4L2_CID_MPEG_VIDEO_H264_SCALING_MATRIX
if a non-flat scaling matrix applies to the picture. This is the case if
SPS scaling_matrix_present_flag or PPS pic_scaling_matrix_present_flag
are set, and should be handled by applications.
On one hand, the PPS bitstream syntax element signals the presence of a
Picture scaling matrix modifying the Sequence (SPS) scaling matrix.
On the other hand, our flag should indicate if the scaling matrix
V4L2 control is applicable to this request.
Rename the flag from PPS_FLAG_PIC_SCALING_MATRIX_PRESENT to
PPS_FLAG_SCALING_MATRIX_PRESENT, to avoid mixing this flag with
bitstream syntax element pic_scaling_matrix_present_flag,
and clarify the meaning of our flag.

The H.264 specification requires in section 7.4.3 "Slice header semantics",
that the following values shall be the same in all slice headers:
pic_parameter_set_id
frame_num
field_pic_flag
bottom_field_flag
idr_pic_id
pic_order_cnt_lsb
delta_pic_order_cnt_bottom
delta_pic_order_cnt[ 0 ]
delta_pic_order_cnt[ 1 ]
sp_for_switch_flag
slice_group_change_cycle
These bitstream fields are part of the slice header, and therefore
passed redundantly on each slice. The purpose of the redundancy
is to make the codec fault-tolerant in network scenarios.
This is of course not needed to be reflected in the V4L2 controls,
given the bitstream has already been parsed by applications.
Therefore, move the redundant fields to the per-frame decode
parameters control (DECODE_PARAMS).
Field 'pic_parameter_set_id' is simply removed in this case,
because the PPS control must currently contain the active PPS.
Syntax elements dec_ref_pic_marking() and those related
to pic order count, remain invariant as well, and therefore,
the fields dec_ref_pic_marking_bit_size and pic_order_cnt_bit_size
are also common to all slices.

Currently, the SLICE_BASED and FRAME_BASED modes documentation
is misleading and not matching the intended use-cases.
Drop non-required fields SLICE_PARAMS 'start_byte_offset' and
DECODE_PARAMS 'num_slices' and clarify the decoding modes in the
documentation.
On SLICE_BASED mode, a single slice is expected per OUTPUT buffer,
and therefore 'start_byte_offset' is not needed (since the offset
to the slice is the start of the buffer).
This mode requires the use of CAPTURE buffer holding, and so
the number of slices shall not be required.
On FRAME_BASED mode, the devices are expected to take care of slice
parsing. Neither SLICE_PARAMS are required (and shouldn't be
exposed by frame-based drivers), nor the number of slices.

The SLICE_PARAMS control is intended for slice-based

To reduce the API surface drop the size from the
SLICE_PARAMS control.
A follow-up change will remove other members in SLICE_PARAMS
so we don't need to add padding fields here.

DPB entry PicNum maximum value is 2*MaxFrameNum for interlaced

As specified, MaxFrameNum is 2^(log2_max_frame_num_minus4 + 4)

which means pic_num should be a 32-bit field.

Slice header syntax element 'first_mb_in_slice' can point
to the last macroblock, currently the field can only reference
65536 macroblocks which is insufficient for 8K videos.
Although unlikely, a 8192x4320 video (where macroblocks are 16x16),
would contain 138240 macroblocks on a frame.
As per the H264 specification, 'first_mb_in_slice' can be up to
PicSizeInMbs - 1, so increase the size of the field to 32-bits.
Note that v4l2_ctrl_h264_slice_params struct will be modified

The prediction weight parameters are only required under

As specified in section 7.3.3 Slice header syntax, the prediction
weight table is present if:
((weighted_pred_flag && (slice_type == P || slice_type == SP)) || \
(weighted_bipred_idc == 1 && slice_type == B))
Given its size, it makes sense to move this table to its control,
so applications can avoid passing it if the slice doesn't specify it.
Before this change struct v4l2_ctrl_h264_slice_params was 960 bytes.
With this change, it's 188 bytes and struct v4l2_ctrl_h264_pred_weight

If a driver calls (_)vb2_fop_release(), then such a driver should also
call vb2_video_unregister_device() instead of video_unregister_device().
This helper will call vb2_queue_release() if a filehandle is marked as
owner of the queue. This ensures that at unregister time any streaming
is cancelled and all buffers are returned to userspace.
This is very useful for complex drivers since this stops all streaming
in all subdevs in the pipeline controlled by this video device. Otherwise
this would be delayed until the owner filehandle is closed, which can be
quite some time later.

When debugging issues that involve more than one video queue, messages
related to multiple queues get interleaved without any easy way to tell
which queue they relate to. Fix this by adding a queue name to
vb2_queue, and printing it in all debug messages in the vb2 core and
V4L2 layers. If the name isn't set by drivers, it is automatically
filled with the queue direction and address.

It also contained a phys_addrs array to store any reported physical

removed as well. The original idea was to let the core keep track of
this information, but nothing was ever done with this. Should this

Extend vb2_buffer and vb2_queue structs with cache management
members.
V4L2 UAPI already contains two buffer flags which user-space,
supposedly, can use to control buffer cache sync:
- V4L2_BUF_FLAG_NO_CACHE_INVALIDATE
- V4L2_BUF_FLAG_NO_CACHE_CLEAN
None of these, however, do anything at the moment. This patch
set is intended to change it.
Since user-space cache management hints are supposed to be
implemented on a per-buffer basis we need to extend vb2_buffer
struct with two new members ->need_cache_sync_on_prepare and
->need_cache_sync_on_finish, which will store corresponding
user-space hints.
In order to preserve the existing behaviour, user-space cache
managements flags will be handled only by those drivers that
permit user-space cache hints. That's the purpose of vb2_queue
->allow_cache_hints member. Driver must set ->allow_cache_hints
during queue initialisation to enable cache management hints
mechanism.

Commit 9495b7e92f ("driver core: platform:
Initialize dma_parms for platform devices") in v5.7-rc5 causes
vb2_dma_contig_clear_max_seg_size() to kfree memory that was not
allocated by vb2_dma_contig_set_max_seg_size().
The assumption in vb2_dma_contig_set_max_seg_size() seems to be that
dev->dma_parms is always NULL when the driver is probed, and the case
where dev->dma_parms has bee initialized by someone else than the driver
(by calling vb2_dma_contig_set_max_seg_size) will cause a failure.
All the current users of these functions are platform devices, which now
always have dma_parms set by the driver core. To fix the issue for v5.7,
make vb2_dma_contig_set_max_seg_size() return an error if dma_parms is
NULL to be on the safe side, and remove the kfree code from
vb2_dma_contig_clear_max_seg_size().
For v5.8 we should remove the two functions and move the
dma_set_max_seg_size() calls into the drivers.

v4l2_fh struct define differently by CONFIG_V4L2_MEM2MEM_DEV.
If some vendors use CONFIG_V4L2_MEM2MEM_DEV by module,
it can make the mismatch of v4l2_fh sturct.
By the mismatch, the following error occurs.
===============================
[ 7.533506] v4l2_mem2mem: disagrees about version of symbol video_devdata
[ 7.533594] v4l2_mem2mem: Unknown symbol video_devdata (err -22)

[ 7.542532] v4l2_mem2mem: Unknown symbol v4l2_event_pending (err -22)
===============================
So v4l2_fh struct is modified to does not have dependency
for CONFIG_V4L2_MEM2MEM_DEV.

If the kernel is built without e.g. the imon IR decoder, the protocols
sysfs file still show the protocol as available. If user-space tries to
enable this decoder, the kernel will report an error:
$ echo +imon > /sys/class/rc/rc0/protocols
[ 57.693033] rc_core: Loaded IR protocol module ir-imon-decoder, but protocol imon still not available
Ensuring that unavailable protocols are not advertised, ensures that
users space knows it is not available, and a BPF based IR decoder can be
loaded instead.
This supports the case when no kernel-based codec needs to be compiled in,
and every IR decoder can be BPF based.

Add helpers for JPEG header parsing. They allow both scanning for marker
segment positions and later parsing the segments individually, as
required by s5p-jpeg, as well as parsing all headers in one go, as
required by coda-vpu. The frame header is always parsed, as basically
all decoders are interested in width, height, and number of components.
For convenience, the JPEG chroma subsampling factors are decoded into a
v4l2_jpeg_chroma_subsampling enum.
Only baseline and extended sequential DCT encoded JPEGs with 8-bit or
12-bit precision with up to four components are supported.

Currently every driver needs to parse the connector endpoints by it self.
This is the initial work to make this generic. A generic connector has
common members and connector specific members. The common members are:
- type
- label (optional)
- links
- nr_of_links
The specific members are stored within a union, since only one of them
can be available at the time. Since this is the initial support the
patch adds only the analog-connector specific ones.

There are many protocols that encode more than 32 bit. We want 64 bit
support so that BPF IR decoders can decode more than 32 bit. None of
the existing kernel IR decoders/encoders support 64 bit, for now.
The MSC_SCAN event can only contain 32 bit scancodes, so we only generate
MSC_SCAN events if the scancode fits into 32 bits. The full 64 bit
scancode can be read from the lirc chardev.

Since the draining and stop phase of the HW decoder mem2mem bahaviour is
now clearly defined, we can move handling of the following states to the
common v4l2-mem2mem core code:
- draining
- stopped
- next-buf-is-last
By introducing the following v4l2-mem2mem APIs:
- v4l2_m2m_encoder_cmd/v4l2_m2m_ioctl_encoder_cmd to handle start/stop command
- v4l2_m2m_decoder_cmd/v4l2_m2m_ioctl_decoder_cmd to handle start/stop command
- v4l2_m2m_update_start_streaming_state to update state on start of streaming
of the de/encoder queue
- v4l2_m2m_update_stop_streaming_state to update state on stop of streaming
of the de/encoder queue
- v4l2_m2m_last_buffer_done to make the current dest buffer as the last one
And inline helpers:
- v4l2_m2m_mark_stopped to mark the de/encoding process as stopped
- v4l2_m2m_clear_state to clear the de/encoding state
- v4l2_m2m_dst_buf_is_last to detect the current dequeued dst_buf is the last
- v4l2_m2m_has_stopped to detect the de/encoding stopped state
- v4l2_m2m_is_last_draining_src_buf to detect the current source buffer should
be the last processing before stopping the de/encoding process
The special next-buf-is-last when min_buffers != 1 case is also handled
in v4l2_m2m_qbuf() by reusing the other introduced APIs.
This state management has been stolen from the vicodec implementation,
and is no-op for drivers not calling the v4l2_m2m_encoder_cmd or
v4l2_m2m_decoder_cmd and v4l2_m2m_update_start/stop_streaming_state.
The vicodec will be the first one to be converted as an example.

Currently, v4l2_pipeline_pm_use() prototype is:
int v4l2_pipeline_pm_use(struct media_entity *entity, int use)
Where the 'use' argument shall only be set to '1' for enable/power-on,
or to '0' for disable/power-off. The integer return is specified
as only meaningful when 'use' is set to '1'.
Let's enforce this semantic by splitting the function in two:
v4l2_pipeline_pm_get and v4l2_pipeline_pm_put. This is done
for several reasons.
It makes the API easier to use (or harder to misuse).
It removes the constraint on the values the 'use' argument
shall take. Also, it removes the need to constraint
the return value, by making v4l2_pipeline_pm_put void return.
And last, it's more consistent with other kernel APIs, such
as the runtime pm APIs, which makes the code more symmetric.

boundary->width and boundary->height are sizes relative to

taken into consideration to adjust r->left and r->top, leading to the
following error:
Consider the follow as initial values for boundary and r:
struct v4l2_rect boundary = {
.left = 100,
.top = 100,
.width = 800,
.height = 600,
}
struct v4l2_rect r = {
.left = 0,
.top = 0,
.width = 1920,
.height = 960,

calling v4l2_rect_map_inside(&r, &boundary) was modifying r to:
r = {
.left = 0,
.top = 0,
.width = 800,
.height = 600,
}
Which is wrongly outside the boundary rectangle, because:
v4l2_rect_set_max_size(r, boundary); // r->width = 800, r->height = 600
...
if (r->left + r->width > boundary->width) // true
r->left = boundary->width - r->width; // r->left = 800 - 800
if (r->top + r->height > boundary->height) // true
r->top = boundary->height - r->height; // r->height = 600 - 600
Fix this by considering top/left coordinates from boundary.

The v4l2_buffer structure contains a 'struct timeval' member that is
defined by the user space C library, creating an ABI incompatibility
when that gets updated to a 64-bit time_t.
As in v4l2_event, handle this with a special case in video_put_user()
and video_get_user() to replace the memcpy there.
Since the structure also contains a pointer, there are now two
native versions (on 32-bit systems) as well as two compat versions
(on 64-bit systems), which unfortunately complicates the compat
handler quite a bit.
Duplicating the existing handlers for the new types is a safe
conversion for now, but unfortunately this may turn into a
maintenance burden later. A larger-scale rework of the
compat code might be a better alternative, but is out of scope
of the y2038 work.
Sparc64 needs a special case because of their special suseconds_t

The v4l2_event structure contains a 'struct timespec' member that is
defined by the user space C library, creating an ABI incompatibility
when that gets updated to a 64-bit time_t.
While passing a 32-bit time_t here would be sufficient for CLOCK_MONOTONIC
timestamps, simply redefining the structure to use the kernel's
__kernel_old_timespec would not work for any library that uses a copy
of the linux/videodev2.h header file rather than including the copy from
the latest kernel headers.
This means the kernel has to be changed to handle both versions of the
structure layout on a 32-bit architecture. The easiest way to do this
is during the copy from/to user space.

When building with Clang + -Wtautological-constant-compare, several of

result of '<<' to a boolean always evaluates to true

'CX18_HW_GPIO_RESET_CTRL'
#define CX18_HW_GPIO_RESET_CTRL (1 << 6)
^
1 warning generated.
This warning happens because the shift operation is implicitly converted
to a boolean in v4l2_device_mask_call_all before being negated. This can
be solved by just comparing the mask result to 0 explicitly so that
there is no boolean conversion. The ultimate goal is to enable
-Wtautological-compare globally because there are several subwarnings
that would be helpful to have.
For visual consistency and avoidance of these warnings in the future,
all of the implicitly boolean conversions in the v4l2_device macros
are converted to explicit ones as well.

They are not exported to the public V4L2 API since reworking this API
will likely be needed for covering various use-cases and new hardware.
Multi-slice decoding is exposed as a valid decoding mode to match current
H.264 support but it is not yet implemented.
The interface comes with the following limitations:
* No custom quantization matrices (scaling lists);
* Support for a single temporal layer only;
* No slice entry point offsets support;
* No conformance window support;
* No VUI parameters support;
* No support for SPS extensions: range, multilayer, 3d, scc, 4 bits;
* No support for PPS extensions: range, multilayer, 3d, scc, 4 bits.

Add v4l2_m2m_buf_done_and_job_finish() to correctly return source

a held destination buffer into account (i.e. that buffer won't be

It is often useful to figure out if a pixel_format is either YUV or RGB
especially for driver who can perform the pixel encoding conversion.
Instead of having each driver implement its own "is_this_yuv/rgb"
function based on a restricted set of pixel value, it is better to do
this in centralized manner.
We therefore add a pixel_enc member to the v4l2_format_info structure to
quickly identify the related pixel encoding.
And add helper functions to check pixel encoding.

It is possible for one HDMI connector to have multiple CEC adapters. The
typical real-world scenario is that where one adapter is used when the
device is in standby, and one that's better/smarter when the device is
powered up.
The cec-notifier changes were made with that in mind, but I missed that in
order to support this you need to tell cec_notifier_cec_adap_unregister()
which adapter you are unregistering from the notifier.
Add this additional argument. It is currently unused, but once all drivers
use this, the CEC core will be adapted for these use-cases.

Drivers are allowed to support only one start code type,

Note that this is independent of the H264 decoding mode,
which specifies the granularity of the decoding operations.

The v4l2_async_notifier_add_fwnode_subdev() did not take a reference of
the added fwnode, relying on the caller to handle that instead, in essence
putting the fwnode to be added if there was an error.
As the reference is eventually released during the notifier cleanup, this
is not intuitive nor logical. Improve this by always getting a reference
when the function succeeds, and the caller releasing the reference when it
does not *itself* need it anymore.
Luckily, perhaps, there were just a handful of callers using the function.
