leds: support new LP8501 device - another LP55xx common
LP8501 can drive up to 9 channels like LP5523. LEDs can be controlled directly via the I2C and programmable engines are supported. LP55xx common driver LP8501 is one of LP55xx family device, so LP55xx common code are used. Chip specific data is defined in the structure, 'lp55xx_device_config'. Differences between LP8501 and LP5523 Different register layout for LED output control and others. LP8501 specific feature for separate output power selection. LP8501 doesn't support external clock detection. Different programming engine data. LP8501 specific feature - output power selection Output channels are selected by power selection - Vout or Vdd. Separate power for VDD1-6 and VDD7-9 are available. It is configurable in the platform data. To support this feature, LP55xx DT structure and header are changed. Device tree binding is updated as well. LED pattern data Example pattern data is updated in the driver documentation.

+ If you say yes here you get support for TI LP8501 LED driver.
+ It is 9 channel chip with programmable engines.

+ It is similar as LP5523, but output power selection is available.
+ And register layout and engine program schemes are different.
