The four or six high-precision current sinks support phase shifting that is automatically adjusted based on the number of channels in use. LED brightness can be controlled globally through the I2C interface or PWM input. Add new DT bindings for ti,lp8864 to support all four software-compatible devices: - LP8864 - LP8864S - LP8866 - LP8866S Add leds class driver for these devices.
