Hi, When I check "rockchip,gpio-bank" with YAML it turns out that rk3288-veyron-XXX has 'gpio-line-names' as 'extra' property. It is not defined in the "rockchip,pinctrl.txt" document, but in ~/.local/lib/python3.5/site-packages/dtschema/schemas/gpio/gpio.yaml Where is that in use? In this driver or external? Can it be removed from mainline dts? Johan /arch/arm/boot/dts/rk3288-veyron-fievel.dt.yaml: gpio7@ff7e0000: 'gpio-line-names' does not match any of the regexes: 'pinctrl-[0-9]+' From schema: /Documentation/devicetree/bindings/gpio/rockchip,gpio-bank.yaml On 4/11/21 3:30 PM, Peter Geis wrote: > From: Jianqun Xu <jay.xu@xxxxxxxxxxxxxx> > > Separate the gpio driver from the pinctrl driver. > > Signed-off-by: Jianqun Xu <jay.xu@xxxxxxxxxxxxxx> > ---
