TI LMU (Lighting Management Unit) driver supports lighting devices below. LM3532, LM3631, LM3632, LM3633, LM3695 and LM3697. LMU devices have common features. - I2C interface for accessing device registers - Hardware enable pin control - Backlight brightness control - Notifier for hardware fault monitoring - Regulators for LCD display bias It contains fault monitor, backlight, LED and regulator driver. LMU fault monitor ----------------- LM3633 and LM3697 provide hardware monitoring feature. It enables open or short circuit detection. After monitoring is done, each device should be re-initialized. Notifier is used for this case. Separate patch for 'ti-lmu-fault-monitor' will be sent later. Backlight --------- It's handled by TI LMU backlight consolidated driver and chip dependent data. Separate patchset will be sent later. LED indicator ------------- LM3633 has 6 indicator LEDs. Programmable dimming pattern is also supported. Separate patch for 'leds-lm3633' will be sent later. Regulator --------- LM3631 has 5 regulators for the display bias. LM3632 supports 3 regulators. One consolidated driver enables it. The lm363x regulator driver is already upstreamed.
