title: LEDs connected to Broadcom BCM6358 controller
|
||||
|
||||
description: |
|
||||
This controller is present on BCM6358 and BCM6368.
|
||||
In these SoCs there are Serial LEDs (LEDs connected to a 74x164 controller),
|
||||
which can either be controlled by software (exporting the 74x164 as spi-gpio.
|
||||
See Documentation/devicetree/bindings/gpio/fairchild,74hc595.yaml), or
|
||||
by hardware using this driver.

LEDs connected to Broadcom BCM6358 controller
|
||||
|
||||
This controller is present on BCM6358 and BCM6368.
|
||||
In these SoCs there are Serial LEDs (LEDs connected to a 74x164 controller),
|
||||
which can either be controlled by software (exporting the 74x164 as spi-gpio.
|
||||
See Documentation/devicetree/bindings/gpio/fairchild,74hc595.yaml), or
|
||||
by hardware using this driver.
|
||||
|
||||
Required properties:
|
||||
- compatible : should be "brcm,bcm6358-leds".
|
||||
- #address-cells : must be 1.
|
||||
- #size-cells : must be 0.
|
||||
- reg : BCM6358 LED controller address and size.
|
||||
|
||||
Optional properties:
|
||||
- brcm,clk-div : SCK signal divider. Possible values are 1, 2, 4 and 8.
|
||||
Default : 1
|
||||
- brcm,clk-dat-low : Boolean, makes clock and data signals active low.
|
||||
Default : false
|
||||
|
||||
Each LED is represented as a sub-node of the brcm,bcm6358-leds device.
|
||||
|
||||
LED sub-node required properties:
|
||||
- reg : LED pin number (only LEDs 0 to 31 are valid).
|
||||
|
||||
LED sub-node optional properties:
|
||||
- label : see Documentation/devicetree/bindings/leds/common.txt
|
||||
- default-state : see
|
||||
Documentation/devicetree/bindings/leds/common.txt
