Si-En Technology was acquired by ISSI in 2011, and it appears that
the IS31FL3218/IS31FL3216 are just rebranded SN3218/SN3216 devices.
Add the "si-en,sn3218" and "si-en,sn3216" compatible strings into the
IS31FL32XX driver as aliases for the issi equivalents, and update
binding documentation.

- compatible: one of
|
|
issi,is31fl3236
|
|
issi,is31fl3235
|
|
issi,is31fl3218
|
|
issi,is31fl3216
|
|
si-en,sn3218
|
|
si-en,sn3216
|
|
- reg: I2C slave address
|
|
- address-cells : must be 1
|
|
- size-cells : must be 0

|
|
is31fl3236: led-controller@3c {
|
|
compatible = "issi,is31fl3236";
|
|
reg = <0x3c>;
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
|
|
led@1 {
|
|
reg = <1>;
|
|
label = "EB:blue:usr0";
|
|
};
|
|
led@2 {
|
|
reg = <2>;
|
|
label = "EB:blue:usr1";
