      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/fairchild,74hc595.yaml), 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
     30  - default-state : see
     31    Documentation/devicetree/bindings/leds/common.txt
     32  - linux,default-trigger : see
     33    Documentation/devicetree/bindings/leds/common.txt
