      1Qualcomm PM8058 LED driver
      2
      3The Qualcomm PM8058 is a multi-functional device which contains
      4an LED driver block for up to six LEDs: three normal LEDs, two
      5"flash" LEDs and one "keypad backlight" LED. The names are
      6quoted because sometimes these LED drivers are used for wildly
      7different things than flash or keypad backlight: their names
      8are more of a suggestion than a hard-wired usecase.
      9
     10Hardware-wise the different LEDs support slightly different
     11output currents. The "flash" LEDs do not need to charge nor
     12do they support external triggers. They are just powerful LED
     13drivers.
     14
     15The LEDs appear as children to the PM8058 device, with the
     16proper compatible string. For the PM8058 bindings see:
     17mfd/qcom-pm8xxx.txt.
     18
     19Each LED is represented as a sub-node of the syscon device. Each
     20node's name represents the name of the corresponding LED.

     24Required properties:
     25- compatible: one of
     26  "qcom,pm8058-led" (for the normal LEDs at 0x131, 0x132 and 0x133)
     27  "qcom,pm8058-keypad-led" (for the "keypad" LED at 0x48)
     28  "qcom,pm8058-flash-led" (for the "flash" LEDs at 0x49 and 0xFB)
     29
     30Optional properties:
     31- label: see Documentation/devicetree/bindings/leds/common.txt
     32- default-state: see Documentation/devicetree/bindings/leds/common.txt
     33- linux,default-trigger: see Documentation/devicetree/bindings/leds/common.txt
