drm/imx/ipuv3: Fix front porch adjustment upon hactive aligning

2023-07-28T15:20:26+00:00

When hactive is not aligned to 8 pixels, it is aligned accordingly and
hfront porch needs to be reduced the same amount. Unfortunately the front
porch is set to the difference rather than reducing it. There are some
Samsung TVs which can't cope with a front porch of instead of 70.

drm/imx: Use GEM DMA fbdev emulation

2023-03-14T16:07:48+00:00

Use the fbdev emulation that is optimized for DMA helpers. Avoids
possible shadow buffering and makes the code simpler.

drm: Drop ARCH_MULTIPLATFORM from dependencies

2023-03-14T11:57:22+00:00

Some of these dependencies used to be sensible when only a small part of
the platforms supported by ARCH=arm could be compiled together in a
single kernel image. Nowadays ARCH_MULTIPLATFORM is only used as a guard
for kernel options incompatible with a multiplatform image. See commit
84fc86360623 ("ARM: make ARCH_MULTIPLATFORM user-visible") for some more
details.

drm/imx: move IPUv3 driver into separate subdirectory

2022-12-16T17:40:29+00:00

The IPUv3 and DCSS driver are two totally separate DRM drivers. Having
one of them live in the drivers/gpu/drm/imx toplevel directory and the
other one in the dcss/ subdirectory is confusing. Move the IPUv3 driver
into its own subdirectory to make the separation more clear.
