* 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
|
||
|
|
