Subject: [PATCH v3 1/3] 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
If the led node is present in the controller then the channel is
set to active.
Signed-off-by: Vicentiu Galanopulo <vicentiu.galanopulo@...ote-tech.co.uk>

Changes in v3:
- remove active property
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
