51c84a8aac media: mediatek: vcodec: adding lock to protect encoder context list
[ Upstream commit afaaf3a0f6 ]

Add a lock for the ctx_list, to avoid accessing a NULL pointer
within the 'vpu_enc_ipi_handler' function when the ctx_list has
been deleted due to an unexpected behavior on the SCP IP block.

521ce0ea74 media: mediatek: vcodec: Fix oops when HEVC init fails
[ Upstream commit 97c75ee5de ]

The stateless HEVC decoder saves the instance pointer in the context
regardless if the initialization worked or not. This caused a use after
free, when the pointer is freed in case of a failure in the deinit
function.
Only store the instance pointer when the initialization was successful,
to solve this issue.

afde78ea48 media: nxp: imx8-isi: Mark all crossbar sink pads as MUST_CONNECT
[ Upstream commit 9b71021b2e ]

All the sink pads of the crossbar switch require an active link if
they're part of the pipeline. Mark them with the
MEDIA_PAD_FL_MUST_CONNECT flag to fail pipeline validation if they're
not connected. This allows removing a manual check when translating
streams.

91c8ce42fc media: nxp: imx8-isi: Check whether crossbar pad is non-NULL before access
[ Upstream commit eb2f932100 ]

When translating source to sink streams in the crossbar subdev, the
driver tries to locate the remote subdev connected to the sink pad. The
remote pad may be NULL, if userspace tries to enable a stream that ends
at an unconnected crossbar sink. When that occurs, the driver
dereferences the NULL pad, leading to a crash.

Prevent the crash by checking if the pad is NULL before using it, and
return an error if it is.

[ Upstream commit bfb1b99802 ]

The ipi handler here tries hard to maintain const-ness of its argument,
but by doing that causes a warning about function type casts:

drivers/media/platform/mediatek/vcodec/common/mtk_vcodec_fw_vpu.c:38:32: error: cast from 'mtk_vcodec_ipi_handler' (aka 'void (*)(void *, unsigned int, void *)') to 'ipi_handler_t' (aka 'void (*)(const void *, unsigned int, void *)') converts to incompatible function type [-Werror,-Wcast-function-type-strict]
   38 |         ipi_handler_t handler_const = (ipi_handler_t)handler;
      |                                       ^~~~~~~~~~~~~~~~~~~~~~

Remove the hack and just use a non-const argument.

244bface03 media: sun8i-di: Fix coefficient writes
[ Upstream commit 794b581f8c ]

Currently coefficients are applied only once, since they don't change.
However, this is done before enable bit is set and thus it doesn't get
applied properly.

Fix that by applying coefficients after enable bit is set. While this
means that it will be done evey time, it doesn't bring much time
penalty.

ffb635bb39 media: rkisp1: Fix IRQ handling due to shared interrupts
The driver requests the interrupts as IRQF_SHARED, so the interrupt
handlers can be called at any time. If such a call happens while the ISP
is powered down, the SoC will hang as the driver tries to access the
ISP registers.

This can be reproduced even without the platform sharing the IRQ line:
Enable CONFIG_DEBUG_SHIRQ and unload the driver, and the board will
hang.

Fix this by adding a new field, 'irqs_enabled', which is used to bail
out from the interrupt handler when the ISP is not operational.

bc0e8d91fe ("media: v4l: subdev: Switch to stream-aware state
functions") caused the sd pointer of the state passed to the
v4l2_subdev_state_get_crop() function to be dereferenced. It however
missed that the atmel-isi driver creates the v4l2_subdev_state instance
on the stack (which it shouldn't do, but that's a separate problem),
without initializing the sd field. This results in a null pointer
dereference.

Fix it by initializing the sd field.

efa28efd9c media: rkisp1: resizer: Stop manual allocation of v4l2_subdev_state
Supported media bus codes on the resizer sink pad are identical to the
ISP source pad. The .enum_mbus_code() handler thus delegates the
enumeration to the ISP's operation. This is problematic for two
reasons:

- Format enumeration on the ISP source pad is dependent on the format
  configured on the ISP sink pad for the same subdev state (TRY or
  ACTIVE), while format enumeration on the resizer sink pad should
  return all formats supported by the resizer subdev, regardless of the
  ISP configuration.

- Delegating the operation involves creating a fake v4l2_subdev_state on
  the stack to pass to the ISP .enum_mbus_code() handler. This gets in
  the way of evolution of both the ISP enumeration handler and, more
  generally, the V4L2 subdev state infrastructure.

Fix those two issues by implementing format enumeration manually for the
resizer.

870565f063 media: rkisp1: Fix IRQ disable race issue
In rkisp1_isp_stop() and rkisp1_csi_disable() the driver masks the
interrupts and then apparently assumes that the interrupt handler won't
be running, and proceeds in the stop procedure. This is not the case, as
the interrupt handler can already be running, which would lead to the
ISP being disabled while the interrupt handler handling a captured
frame.

This brings up two issues: 1) the ISP could be powered off while the
interrupt handler is still running and accessing registers, leading to
board lockup, and 2) the interrupt handler code and the code that
disables the streaming might do things that conflict.

It is not clear to me if 2) causes a real issue, but 1) can be seen with
a suitable delay (or printk in my case) in the interrupt handler,
leading to board lockup.

5705b0e0eb media: imx-mipi-csis: Fix clock handling in remove()
The driver always calls mipi_csis_runtime_suspend() and
mipi_csis_clk_disable() in remove(). This causes multiple WARNs from the
kernel, as the clocks get disabled too many times.

Fix the remove() to call mipi_csis_runtime_suspend() and
mipi_csis_clk_disable() in a way that reverses what is done in probe().

Include all the headers that the driver needs explicitly instead of
relying on indirect inclusion. While at it, drop a few unneeded headers.

db71a7f5cb media: rockchip: rga: add NV12M support
Add support for the multi-planar variants of NV12. The RGA is now able
to exchange DMABUFs with other devices that only support multi-planar
NV12, for example the Hantro JPEG encoder.

a61ff67ffb media: rockchip: rga: rework buffer handling for multi-planar formats
Multi-planar formats may have multiple planes that must be handled and
correctly mapped into a continuous buffer for the RGA by using the DMA
descriptors.

The plane offsets in the continuous mapping may now start at page
boundaries and the previous calculation based on the frame sizes is only
valid for planar buffers in a single memory. Therefore, the offsets must
be detected and set while creating the mapping.

0148bcd77d media: rockchip: rga: switch to multi-planar API
Switch to the multi-planar API, which allows to handle buffers with
separate planes.

The RGA driver doesn't expose multi-planar formats, yet. The existing
contiguous planar formats can be used with the multi-planar API as well,
but the multi-planar API is required for multi-planar formats.

2addee7aef media: rockchip: rga: use macros for testing buffer type
Use the provided V4L2_TYPE_IS_{OUTPUT,CAPTURE} macros to check if the
buffer or queue is OUTPUT or CAPTURE. The macros work also work for the
_MPLANE buffer and queue types and make it easier to switch to the
multi-planar API.
