mfd: Add TI LMU driver
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.
