7415287e1f drm: move tinydrm format conversion helpers to new drm_format_helper.c
Also rename them from tinydrm_* to drm_fb_*

96f2a9aef5 drm/tinydrm: tinydrm_display_pipe_init() don't use tinydrm_device
Rework function signature so tinydrm_device can be avoided.

Move definition to tinydrm-helpers.h so tinydrm.h can be deleted in a
later patch.

af74138160 drm/tinydrm: Use damage helper for dirtyfb
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

b051b3459b drm/tinydrm: Use struct drm_rect
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.

e85d30060e drm/tinydrm: Make fb_dirty into a lower level hook
mipi_dbi_enable_flush() wants to call the fb->dirty() hook from the
bowels of the .atomic_enable() hook. That prevents us from taking the
plane mutex in fb->dirty() unless we also plumb down the acquire
context.

Instead it seems simpler to split the fb->dirty() into a tinydrm
specific lower level hook that can be called from
mipi_dbi_enable_flush() and from a generic higher level
tinydrm_fb_dirty() helper. As we don't have a tinydrm specific
vfuncs table we'll just stick it into tinydrm_device directly
for now.

v2: Deal with the fb->dirty() in tinydrm_display_pipe_update() as well (Noralf)

d1a2e7004b drm/tinydrm: Replace tinydrm_of_find_backlight with of_find_backlight
Remove tinydrm_of_find_backlight from tinydrm-helpers.c. We now have
a generic of_find_backlight defined in backlight.c. Let the callers
of tinydrm_of_find_backlight call of_find_backlight. Also, remove
select BACKLIGHT_LCD_SUPPORT and select BACKLIGHT_CLASS_DEVICE from
tinydrm/Kconfig as it is a hack that is no longer needed.

dma_buf_{begin,end}_cpu_access() are moved out to the repaper driver.

Return type is change to void to simplify error handling by callers.
