Binding for TI/National Semiconductor LP55xx Led Drivers
Required properties:
- compatible: one of
national,lp5521
national,lp5523
ti,lp55231
ti,lp5562
ti,lp8501
- reg: I2C slave address
- clock-mode: Input clock mode, (0: automode, 1: internal, 2: external)
Each child has own specific current settings
- led-cur: Current setting at each led channel (mA x10, 0 if led is not connected)
- max-cur: Maximun current at each led channel.
Optional properties:
- enable-gpio: GPIO attached to the chip's enable pin
- label: Used for naming LEDs
- pwr-sel: LP8501 specific property. Power selection for output channels.
0: D1~9 are connected to VDD
1: D1~6 with VDD, D7~9 with VOUT
2: D1~6 with VOUT, D7~9 with VDD
3: D1~9 are connected to VOUT
Alternatively, each child can have a specific channel name and trigger:
- chan-name (optional): name of channel
- linux,default-trigger (optional): see
Documentation/devicetree/bindings/leds/common.txt
example 1) LP5521
3 LED channels, external clock used. Channel names are 'lp5521_pri:channel0',
'lp5521_pri:channel1' and 'lp5521_pri:channel2', with a heartbeat trigger
on channel 0.
lp5521@32 {
compatible = "national,lp5521";
reg = <0x32>;
label = "lp5521_pri";
clock-mode = /bits/ 8 <2>;
chan0 {
led-cur = /bits/ 8 <0x2f>;
max-cur = /bits/ 8 <0x5f>;
linux,default-trigger = "heartbeat";
};
chan1 {
led-cur = /bits/ 8 <0x2f>;
max-cur = /bits/ 8 <0x5f>;
};
chan2 {
led-cur = /bits/ 8 <0x2f>;
max-cur = /bits/ 8 <0x5f>;
};
};
example 2) LP5523
9 LED channels with specific name. Internal clock used.
The I2C slave address is configurable with ASEL1 and ASEL0 pins.
Available addresses are 32/33/34/35h.

example 3) LP5562
4 channels are defined.

example 4) LP8501
9 channels are defined. The 'pwr-sel' is LP8501 specific property.
Others are same as LP5523.
