2020-12-10arm64: dts: bitmain: Use generic "ngpios" rather than "snps,nr-gpios"Jisheng Zhang1-3/+3
This is to remove similar errors as below: OF: /.../gpio-port@0: could not find phandle Commit 7569486d79ae ("gpio: dwapb: Add ngpios DT-property support") explained the reason of above errors well and added the generic "ngpios" property, let's use it.

2019-08-03arm64: dts: bitmain: Modify pin controller memory mapManivannan Sadhasivam1-2/+2
Earlier, the PWM registers were included as part of the pinctrl memory map, but this turned to be useless as the muxing is being handled by the SoC pin controller itself. Hence, this commit removes the pwm register mapping from the pinctrl node to make it more clean.
