Hi I cannot find the electrical ratings for GPIO pins in the hardware reference manual, anyone could point me in the right direction?
I was looking for how much current it is possible to source or sink from a gpio on the hikey960 board.
The drive-strength is configurable from 2mA to 32mA, not sure what is the default value when controlling gpio from userspace, but for drivers gpios are configured in device-tree (arch/arm64/boot/dts/hisilicon/hikey-pinctrl.dtsi).
