tinydrm: add backlight dependency

2018-02-28T20:08:56Z

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.

drm/tinydrm: Replace tinydrm_of_find_backlight with of_find_backlight

2018-02-20T16:07:22Z

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.

tinydrm: repaper: add CONFIG_THERMAL dependency

2017-07-29T12:41:39Z

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.
