drm/tinydrm: Use damage helper for dirtyfb

2019-01-17T09:57:15+00:00

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

drm/tinydrm: Use struct drm_rect

2019-01-17T09:57:03+00:00

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.

drm/tinydrm: Use DRM_GEM_CMA_VMAP_DRIVER_OPS

2018-11-20T13:58:19+00:00

The CMA helper now has the functionality to ensure a virtual address on
imported buffer so use that.

While touching all tinydrm drivers, remove the unnecessary inclusion of
drm_fb_helper.h in some drivers.

drm: Move simple_display_pipe prepare_fb helper into gem fb helpers

2018-04-24T11:57:22+00:00

There's nothing tinydrm specific to this, and there's a few more
copies of the same in various other drivers.

drm/tinydrm: Make fb_dirty into a lower level hook

2018-03-28T16:19:32+00:00

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)

drm/tinydrm: Use gem_free_object_unlocked

2018-03-27T08:19:42+00:00

tinydrm doesn't use dev->struct_mutex and therefore has no need to use
gem_free_object.

drm/tinydrm: Replace tinydrm_of_find_backlight with of_find_backlight

2018-02-20T16:07:22+00:00

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.
