-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.
