7628166d5e tinydrm: add backlight dependency
Calling devm_of_find_backlight directly means we get a link failure
without CONFIG_BACKLIGHT_CLASS_DEVICE:

drivers/gpu/drm/tinydrm/mi0283qt.o: In function `mi0283qt_probe':
mi0283qt.c:(.text+0x684): undefined reference to `devm_of_find_backlight'

This adds an explicit Kconfig dependency for it. While I did not
observe that failure for st7735r, I assume the same change is needed
there for the same reason.

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.

b57e8b7661 drm/tinydrm: add driver for ILI9225 panels
This adds a new driver for display panels based on the Ilitek ILI9225
controller.

This was developed for a no-name panel with a red PCB that is commonly
marketed for Arduino. See <https://github.com/Nkawu/TFT_22_ILI9225>.

8312a3fe84 tinydrm: repaper: add CONFIG_THERMAL dependency
The new RePaper driver uses the thermal subsystem, and fails to link
when it is built-in but thermal is a loadable module:

drivers/gpu/drm/tinydrm/repaper.o: In function `repaper_probe':
repaper.c:(.text+0x540): undefined reference to `thermal_zone_get_zone_by_name'
drivers/gpu/drm/tinydrm/repaper.o: In function `repaper_fb_dirty':
repaper.c:(.text+0xff4): undefined reference to `thermal_zone_get_temp'

This adds another Kconfig dependency to prevent the broken configuration,
forcing repaper to be a module too.

This adds support for the Pervasive Displays RePaper branded displays.
The controller code is taken from the userspace driver available
through repaper.org. Only the V231 film is supported since the others
are EOL.
