Currently only linear formats are supported in sun4i-drm driver, but
SoCs like H6 supports AFBC variant of some of them in multiple cores
(GPU, VPU, DE3). Panfrost already implements AFBC compression and is
sometimes confused what should be default choice (linear, AFBC) if DRM
driver is not explicit about modifier support (MiniMyth2 distro with
MythTV app).
After some discussion with Daniel Stone on #panfrost IRC, it was decided
to make modifiers in sun4i-drm explicit, to avoid any kind of guessing,
not just in panfrost, but everywhere. In fact, long term idea is to make
modifier parameter in drm_universal_plane_init() mandatory (non NULL).

The new gpiod interface takes care of parsing the GPIO flags and to

to it simplifies a lot the driver.

If the of_get_named_gpio_flags call fails in vc4_hdmi_bind, we jump to
the err_unprepare_hsm label. That label will then call
pm_runtime_disable and put_device on the DDC device.
We just retrieved the DDC device, so the latter is definitely justified.
However at that point we still haven't called pm_runtime_enable, so the
call to pm_runtime_disable is not supposed to be there.
