Kernel-4.18.0-80.el8_mc13xxx

• Freescale MC13783/MC13892 Power Management Integrated Circuit (PMIC)

Required properties:

• compatible : Should be “fsl,mc13783” or “fsl,mc13892”

Optional properties:

• fsl,mc13xxx-uses-adc : Indicate the ADC is being used
• fsl,mc13xxx-uses-codec : Indicate the Audio Codec is being used
• fsl,mc13xxx-uses-rtc : Indicate the RTC is being used
• fsl,mc13xxx-uses-touch : Indicate the touchscreen controller is being used

Sub-nodes:

• codec: Contain the Audio Codec node.
  • adc-port: Contain PMIC SSI port number used for ADC.
  • dac-port: Contain PMIC SSI port number used for DAC.
• leds : Contain the led nodes and initial register values in property
  “led-control”. Number of register depends of used IC, for MC13783 is 6,
  for MC13892 is 4, for MC34708 is 1. See datasheet for bits definitions of
  these registers.
  • #address-cells: Must be 1.
  • #size-cells: Must be 0.
    Each led node should contain “reg”, which used as LED ID (described below).
    Optional properties “label” and “linux,default-trigger” is described in
    Documentation/devicetree/bindings/leds/common.txt.
• regulators : Contain the regulator nodes. The regulators are bound using
  their names as listed below with their registers and bits for enabling.
