As the 'reg' property is mandatory in the subnodes, improve the example by adding the unit address to the sysled node. This prevents the following build warning with W=1: Node /soc/aips@70000000/spba@70000000/ecspi@70010000/pmic@0/leds/sysled0 has a reg or ranges property, but no unit name Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com> Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>

* 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.
