Subject: [PATCH v2 1/2] dt-bindings: leds: Add LED1202 LED Controller
The LED1202 is a 12-channel low quiescent current LED driver with:
* Supply range from 2.6 V to 5 V
* 20 mA current capability per channel
* 1.8 V compatible I2C control interface
* 8-bit analog dimming individual control
* 12-bit local PWM resolution
* 8 programmable patterns
Signed-off-by: Vicentiu Galanopulo <vicentiu.galanopulo@...ote-tech.co.uk>

Changes in v2:
- renamed label to remove color from it
- add color property for each node
- add function and function-enumerator property for each node

+description:
+ The LED1202 is a 12-channel low quiescent current LED controller
+ programmable via I2C; The output current can be adjusted separately
+ for each channel by 8-bit analog and 12-bit digital dimming control.
