1LEDs connected to Broadcom BCM6358 controller
2
3This controller is present on BCM6358 and BCM6368.
4In these SoCs there are Serial LEDs (LEDs connected to a 74x164 controller),
5which can either be controlled by software (exporting the 74x164 as spi-gpio.
6See Documentation/devicetree/bindings/gpio/gpio-74x164.txt), or
7by hardware using this driver.
8
9Required properties:
10  - compatible : should be "brcm,bcm6358-leds".
11  - #address-cells : must be 1.
12  - #size-cells : must be 0.
13  - reg : BCM6358 LED controller address and size.
14
15Optional properties:
16  - brcm,clk-div : SCK signal divider. Possible values are 1, 2, 4 and 8.
17    Default : 1
18  - brcm,clk-dat-low : Boolean, makes clock and data signals active low.
19    Default : false
20
21Each LED is represented as a sub-node of the brcm,bcm6358-leds device.
22
23LED sub-node required properties:
24  - reg : LED pin number (only LEDs 0 to 31 are valid).
25
26LED sub-node optional properties:
27  - label : see Documentation/devicetree/bindings/leds/common.txt
28  - active-low : Boolean, makes LED active low.
29    Default : false
