a682169891 imx-drm: cleanups and YUV 4:2:0 memory read/write reduction support
- Remove counter load enable form PRE, which has no effect.
 - Add support for setting the double read/write reduction flag in channel
   parameter memory. This can be used to save some memory bandwidth when
   capturing in YUV 4:2:0 chroma subsampled formats.
 - Allocate DMA channel structures as needed, most of the 64 channels are
   unused or even reserved.
 - Remove unused interrupt busy waiting routine.
 - Set VDIC field order for both AUTO and MAN inputs simultaneously as
   both can't be active at the same time.

Allow to skip writing odd chroma rows by setting the RDRW bit for

fcc8487d47 uapi: export all headers under uapi directories
Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):

the issue by using hardware frame counter present in DECON to serialize
vblank and commit completion events.

a38719b3dc video: fbdev: exynos: Remove old non-working MIPI driver
The old non-DRM Exynos MIPI driver does not support DeviceTree and
requires board files.  Our platforms do not provide such so the driver
is not usable since a long time ago.  All features provided by the
driver (and associated s6e8ax0 panel driver) are already supported by
newer DRM version so the old code can be removed.

cd98e85a6b gpu: ipu-v3: Add queued image conversion support
This patch implements image conversion support using the IC tasks, with
tiling to support scaling to and from images up to 4096x4096. Image
rotation is also supported. Image conversion requests are added to
a run queue under the IC tasks.

The internal API is subsystem agnostic (no V4L2 dependency except
for the use of V4L2 fourcc pixel formats).

Callers prepare for image conversion by calling
ipu_image_convert_prepare(), which initializes the parameters of
the conversion. The caller passes in the ipu and IC task to use for
the conversion, the input and output image formats, a rotation mode,
and a completion callback and completion context pointer:

struct ipu_image_converter_ctx *
ipu_image_convert_prepare(struct ipu_soc *ipu, enum ipu_ic_task ic_task,
                          struct ipu_image *in, struct ipu_image *out,
                          enum ipu_rotate_mode rot_mode,
                          ipu_image_converter_cb_t complete,
                          void *complete_context);

A new conversion context is created that is added to an IC task
context queue. The caller is given the new conversion context,
which can then be passed to the further APIs:

int ipu_image_convert_queue(struct ipu_image_converter_run *run);

This queues the given image conversion request run to a run queue,
and starts the conversion immediately if the run queue is empty. Only
the physaddr's of the input and output image buffers are needed,
since the conversion context was created previously with
ipu_image_convert_prepare(). When the conversion completes, the run
pointer is returned to the completion callback.

void ipu_image_convert_abort(struct ipu_image_converter_ctx *ctx);

This will abort any active or pending conversions for this context.
Any currently active or pending runs belonging to this context are
returned via the completion callback with an error status.

void ipu_image_convert_unprepare(struct ipu_image_converter_ctx *ctx);

Unprepares the conversion context. Any active or pending runs will
be aborted by calling ipu_image_convert_abort().

ac4708fab1 gpu: ipu-v3: Add FSU channel linking support
Adds functions to link and unlink source channels to sink
channels in the FSU:

int ipu_fsu_link(struct ipu_soc *ipu, int src_ch, int sink_ch);
int ipu_fsu_unlink(struct ipu_soc *ipu, int src_ch, int sink_ch);

The channels numbers are usually IDMAC channels, but they can also be
channels that do not transfer data to or from memory. The following
convenience functions can be used in place of ipu_fsu_link/unlink()
when both source and sink channels are IDMAC channels:

int ipu_idmac_link(struct ipuv3_channel *src, struct ipuv3_channel *sink);
int ipu_idmac_unlink(struct ipuv3_channel *src, struct ipuv3_channel *sink);

So far the following links are supported:

IPUV3_CHANNEL_IC_PRP_ENC_MEM -> IPUV3_CHANNEL_MEM_ROT_ENC
PUV3_CHANNEL_IC_PRP_VF_MEM   -> IPUV3_CHANNEL_MEM_ROT_VF
IPUV3_CHANNEL_IC_PP_MEM      -> IPUV3_CHANNEL_MEM_ROT_PP
IPUV3_CHANNEL_CSI_DIRECT     -> IPUV3_CHANNEL_CSI_VDI_PREV

More links can be added to the fsu_link_info[] array.

For all video modes we support currently, we always get 2 slots for
a plane by using the current existing dynamic DMFC FIFO allocation
mechanism.  So, let's change to use the static one to simplify the
code.  This also makes it easier to implement the atomic mode setting
as we don't need to handle allocation failure cases then.
