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.

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.
