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.

f730eceb42 drm/tinydrm/mi0283qt: Let the display pipe handle power
It's better to leave power handling and controller init to the
modesetting machinery using the simple pipe .enable and .disable
callbacks. Remove unused mipi_dbi_pipe_enable().

24e05e7a82 drm/tinydrm/mi0283qt: Remove ili9341.h
No need for a public header file for the command macros.
Just include the necessary ones in the driver.

Also use the MIPI_DCS_PIXEL_FMT_16BIT macro.

d3820952ea drm/tinydrm: Use drm_fb_cma_fbdev_init_with_funcs/fini()
Use drm_fb_cma_fbdev_init_with_funcs() and drm_fb_cma_fbdev_fini() which
relies on the fact that drm_device holds a pointer to the drm_fb_helper
structure. This means that the driver doesn't have to keep track of that.
Also use the drm_fb_helper functions directly.
Remove todo entry.
