    1 Binding for ISSI IS31FL32xx and Si-En SN32xx LED Drivers
    2 
    3 The IS31FL32xx/SN32xx family of LED drivers are I2C devices with multiple
    4 constant-current channels, each with independent 256-level PWM control.
    5 Each LED is represented as a sub-node of the device.
    6 
    7 Required properties:
    8 - compatible: one of
    9         issi,is31fl3236
   10         issi,is31fl3235
   11         issi,is31fl3218
   12         issi,is31fl3216
   13         si-en,sn3218
   14         si-en,sn3216
   15 - reg: I2C slave address
   16 - address-cells : must be 1
   17 - size-cells : must be 0
   18 
   19 LED sub-node properties:
   20 - reg : LED channel number (1..N)
   21 - label :  (optional)
   22   see Documentation/devicetree/bindings/leds/common.txt
   23 - linux,default-trigger :  (optional)

   27 Example:
   28 
   29 is31fl3236: led-controller@3c {
   30         compatible = "issi,is31fl3236";
   31         reg = <0x3c>;
   32         #address-cells = <1>;
   33         #size-cells = <0>;
   34 
   35         led@1 {
   36                 reg = <1>;
   37                 label = "EB:blue:usr0";
   38         };
   39         led@2 {
   40                 reg = <2>;
   41                 label = "EB:blue:usr1";
   42         };
   43         ...
