Subject: Re: [PATCH] ARM: dts: am335x-pocketbeagle: switch to pinconf-single
Date: Wed, 6 Oct 2021 10:29:18 +0300	[thread overview]

* Drew Fustini <> [210826 01:20]:
> Switch the compatible for the am33xx_pinmux pin controller node from
> pinctrl-single to pinconf-single. The only change between these two
> compatibles is that PCS_HAS_PINCONF will be true. This then allows
> pinconf properties to be utilized.
> The purpose of this change is to allow the PocketBeagle to use:
>   pinctrl-single,bias-pullup
>   pinctrl-single,bias-pulldown
> This dts already defines these properites for gpio pins in the default
> pinctrl state but it has no effect unless PCS_HAS_PINCONF is set.
> The bias properties can then be modified on the corresponding gpio lines
> through the gpiod uapi. The mapping between the pins and gpio lines is
> defined by gpio-ranges under the gpio controller nodes in am33xx-l4.dtsi

Thanks applying into omap-for-v5.16/dt.
