Binding for National Semiconductor LP55xx Led Drivers
|
|
|
|
Required properties:
|
|
- compatible: "national,lp5521" or "national,lp5523"
|
|
- label: Used for naming LEDs
|
|
- num-channel: Number of LED channels
|
|
- led-cur: Current setting at each led channel (mA x10, 0 if led is not connected)
|
|
- max-cur: Maximun current at each led channel.
|
|
- clock-mode: Input clock mode, (0: automode, 1: internal, 2: external)
|
|
|
|
example:
|
|
|
|
lp5521@32 {
|
|
compatible = "national,lp5521";
|
|
reg = <0x32>;
|
|
label = "lp5521_pri";
|
|
num-channel = /bits/ 8 <3>;
|
|
led-cur = /bits/ 8 <0x2f 0x2f 0x2f>;
|
|
max-cur = /bits/ 8 <0x5f 0x5f 0x5f>;
|
|
clock-mode = /bits/8 <2>;
|
|
};
