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.

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/dcss: Drop if blocks with always false condition

2023-01-10T14:26:06+00:00

dcss_drv_platform_remove() is only called for a device after
dcss_drv_platform_probe() returned 0. In that case dev_set_drvdata() was
called with a non-NULL value and so dev_get_drvdata() won't return NULL.
