The use of drmP.h is discouraged and removal of it from
drm_modeset_helper.h caused drm/stm to fail to build.
This patch introduce the necessary fixes to prepare for the
drmP.h removal from drm_modeset_helper.h.

syzbot is hitting a lockdep warning [1] because flush_work() is called
without INIT_WORK() after kzalloc() at vkms_atomic_crtc_reset().
Commit 6c234fe37c ("drm/vkms: Implement CRC debugfs API") added
INIT_WORK() to only vkms_atomic_crtc_duplicate_state() side. Assuming
that lifecycle of crc_work is appropriately managed, fix this problem
by adding INIT_WORK() to vkms_atomic_crtc_reset() side.

Move mipi_dsi_dcs_set_display_off() from innolux_panel_disable()
to innolux_panel_unprepare(), so they are consistent with
innolux_panel_enable() and innolux_panel_prepare().
This also fixes some mode check and irq timeout issue in MTK dsi code.
Since some dsi code (e.g. mtk_dsi) have following call trace:
1. drm_panel_disable(), which calls innolux_panel_disable()
2. switch to cmd mode
3. drm_panel_unprepare(), which calls innolux_panel_unprepare()
However, mtk_dsi needs to be in cmd mode to be able to send commands
(e.g. mipi_dsi_dcs_set_display_off() and mipi_dsi_dcs_enter_sleep_mode()),
so we need these functions to be called after the switch to cmd mode happens,
i.e. in innolux_panel_unprepare.

Planar YUV formats come with 3 distinct planes, which requires

third plane.
Our hardware only supports the YUV planes order and in order to support
formats with a YVU plane order, a helper is introduced to indicate
whether to invert the address of the two chroma planes.
Missing definitions for YUV411 and YUV444 input format configuration are
also introduced as support is added for these formats. For the input
sequence part, no configuration is required for planar YUV formats so
zero is returned in that case.

This introduces helpers to quickly check that a provided format info
matches a YUV format with a specific disposition, in commonly-used

The intent of providing helpers taking the format info instead of the
fourcc alone is to avoid the overhead of iterating through all formats
when the whole format info structure is available. As a result, these
helpers are very simple so they are made inline.

This switches to drm_atomic_helper_dirtyfb() as the framebuffer dirty
handler. All flushing will now happen in the pipe functions.
Also enable the damage plane property for all except repaper which can
only do full updates.
ili9225:
This change made ili9225_init() equal to mipi_dbi_init() so use it.
v3: Include vblank header (Sam)
ili9225 and st7586 can't use mipi_dbi_enable_flush() (David)
v2: Remove fb check in mipi_dbi_enable_flush() it can't be NULL

This prepares for the switch to drm_atomic_helper_dirtyfb() in the next
patch. The damage helper returns a drm_rect so switch to that everywhere
including using a pointer in the dirty functions.
This is a non-functional change except for the debug print which looks a
bit different.

The kerneldoc comment for struct dma_fence_array lacks a description
of the "work" member, leading to this docs-build warning:
./include/linux/dma-fence-array.h:54: warning: Function parameter or member 'work' not described in 'dma_fence_array'
Add a description and make the warning go away.

So we have a situation where we do not pull in <linux/types.h>
when building for alpha and for ia64 we need even more definitions
are required.
Two invasive fixes where considered:
- Change all declarations of arch_irqs_disabled_flags() to use bool
- Add include of <linux/types.h> to all files that uses bool for
arch_irqs_disabled_flags
To invasive with a too high pain/benefit ratio, so dropped.
They would not cover ia64 either.
Some less invasive fixes was also considered:
- Add include of <linux/types.h> to drm_util.h
- Add include of <linux/interrupt.h> to drm_util.h
The first was dropped as this did not cover the ia64 case.
The latter was considered the best option as there could
be other similar cases and we would like the header files below
include/drm/ to be selfcontained.
So we end up pulling in a lot of stuff not needed, but this is
the price we pay in drm/ because the kernel headers are not all
selfcontained.
While at it, ordred the includefiles in drm_util in alphabetical order.
Build tested with alpha,ia64,arm,x86 with allmodconfig and allyesconfig.
v2:
- fix ia64 build, changed to include interrupt.h
- sort include files alphabetically

Something that I completely missed when implementing the new MST VCPI
atomic helpers is that with those helpers, there's technically a chance
of us having to grab additional modeset locks in ->compute_config() and
furthermore, that means we have the potential to hit a normal modeset
deadlock. However, because ->compute_config() only returns a bool this
means we can't return -EDEADLK when we need to drop locks and try again
which means we end up just failing the atomic check permanently. Whoops.
So, fix this by modifying ->compute_config() to pass down an actual
error code instead of a bool so that the atomic check can be restarted
on modeset deadlocks.
Thanks to Ville Syrjälä for pointing this out!
Changes since v1:
* Add some newlines
* Return only -EINVAL from hsw_crt_compute_config()
* Propogate return code from intel_dp_compute_dsc_params()
* Change all of the intel_dp_compute_link_config*() variants
* Don't miss if (hdmi_port_clock_valid()) branch in
intel_hdmi_compute_config()

It's a debug hack flag useful to work around driver bugs. That's not a
good idea for a new driver. Especially for a new drm driver.
Aside: the fbdev support should probably be converted over to the new
generic fbdev support.
