The LP5812 is a 4x3 matrix RGB LED driver with an autonomous animation engine and time-cross-multiplexing (TCM) support for up to 12 LEDs or 4 RGB LEDs. Each LED can be configured through the related registers to realize vivid and fancy lighting effects. This patch adds minimal driver support for the LP5812, implementing only the essential functionality: I2C communication with the device, LED registration, brightness control in manual mode, and basic sysfs interfaces for LED configuration and fault monitoring.

This option enables support for monochrome LEDs that are grouped
|

different colors are physically grouped in a single multi-color LED
|

This option enables support for the Light Pulse Generator found in a

|
wide variety of Qualcomm PMICs. The LPG consists of a number of PWM
|
|
channels and typically a shared pattern lookup table and a current
|
|
sink, intended to drive RGB LEDs. Each channel can either be used as
|
|
a LED, grouped to represent a RGB LED or exposed as PWM channels.
|
|
|

If compiled as a module, the module will be named leds-qcom-lpg.
