Re: [PATCH V4 1/2] dt-bindings: pinctrl: qcom: sm6125: Document SM6125 pinctrl driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Corrected all in V5. Added minItems to reg as well
since all the regs are required.

As Rob's bot pointed out, you're missing reg-names here.

 +  interrupts: true
 +  interrupt-controller: true
 +  '#interrupt-cells': true
 +  gpio-controller: true
 +  gpio-reserved-ranges: true
 +  '#gpio-cells': true
 +  gpio-ranges: true
 +  wakeup-parent: true
 +
 +required:
 +  - compatible
 +  - reg

And given the use of tiles, I would suggest that reg-names is required
as well.

Other than that, I think this looks great.

Bjorn
