2024-09-30backlight: otm3225a: Use lcd power constantsThomas Zimmermann
Replace FB_BLANK_ constants with their counterparts from the lcd subsystem. The values are identical, so there's no change in functionality.

2018-04-30backlight: otm3225a: Add support for ORISE OTM3225A LCD SoCFelix Brack
This patch adds a LCD driver supporting the OTM3225A LCD SoC from ORISE Technology. This device can drive TFT LC panels having a resolution of 240x320 pixels. After initializing the OTM3225A using it's SPI interface it switches to use 16-bib RGB as external display interface.
