drm/imx: ipu-v3 plane offset and IPU id fixes

- Fix U/V plane offsets for odd vertical offsets. Due to wrong operator
  order, the y offset was not rounded down properly for vertically
  chroma subsampled planar formats.
- Fix IPU id number for boards that don't have an OF alias for their
  single IPU in the device tree. This is necessary to support imx-media
  on i.MX51 and i.MX53 SoCs.

gpu: ipu-v3: default to id 0 on missing OF alias

2018-08-02T10:09:11+00:00

This is better than storing -ENODEV in the id number. This fixes SoCs
with only one IPU that don't specify an IPU alias in the device tree.

gpu: ipu-v3: add support for XRGB32 and XBGR32 V4L2 pixel formats

2018-08-02T09:32:40+00:00

These should be used instead of the ill-defined deprecated RGB32 and
BGR32 V4L2 pixel formats.

gpu: ipu-v3: make const arrays int_reg static, shrinks object size

2018-02-16T13:47:43+00:00

Don't populate the const read-only arrays int_reg on the stack but instead
make them static. Makes the object code smaller by over 80 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
  28024	   8936	    192	  37152	   9120	drivers/gpu/ipu-v3/ipu-common.o

After:
   text	   data	    bss	    dec	    hex	filename
  27794	   9080	    192	  37066	   90ca	drivers/gpu/ipu-v3/ipu-common.o

gpu: ipu-v3: Allow channel burst locking on i.MX6 only

2017-10-11T08:45:06+00:00

The IDMAC_LOCK_EN registers on i.MX51 have a different layout, and on
i.MX53 enabling the lock feature causes bursts to get lost. Restrict
enabling the burst lock feature to i.MX6.

drm: Convert to using %pOF instead of full_name

2017-07-26T11:45:06+00:00

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

gpu: ipu-v3: remove interrupt busy waiting routine

gpu: ipu-v3: allocate ipuv3_channels as needed

2017-06-08T06:57:19+00:00

Most of the 64 IPUv3 DMA channels are never used, some of them (channels
16, 30, 32, 34-39, and 53-63) are even marked as reserved.
Allocate the channel control structure only when a channel is actually
requested, replace the fixed size array with a list, and remove the
unused enabled and busy fields from the ipuv3_channel structure.

gpu: ipu-v3: Fix CSI selection for VDIC

2017-06-06T08:21:34+00:00

The description of the CSI_SEL bit in the i.MX6 reference manual is
incorrect. It states "This bit defines which CSI is the input to the
IC. This bit is effective only if IC_INPUT is bit cleared".

From experiment it was found this is in fact not correct. The CSI_SEL
bit selects which CSI is input to _both_ the VDIC _and_ the IC. If the
IC_INPUT bit is set so that the IC is receiving from the VDIC, the IC
ignores the CSI_SEL bit, but CSI_SEL still selects which CSI the VDIC
receives from in that case.
