leds: is31fl319x: 1/3/6/9-channel light effect led driver
This is a driver for the Integrated Silicon Solution Inc. LED driver chips series IS31FL319x. They can drive 1, 3, 6 or up to 9 LEDs. Each LED is individually controllable in brightness (through pwm) in 256 steps so that RGB LEDs can show any of ca. 16 Mio colors. The maximum current of the LEDs can be programmed and limited to 5 .. 40mA through a device tree property. The chip is connected through I2C and can have one of 4 addresses in the range 0x64 .. 0x67 depending on how the AD pin is connected. The address is defined by the reg property as usual. The chip also has a shutdown input which could be connected to a GPIO, but this driver uses software shutdown if all LEDs are inactivated. The chip also has breathing and audio features which are not fully supported by this driver. Tested-on: OMAP5 based Pyra handheld prototype. Signed-off-by: H.
