-GPIO pins may need to be in a specific state after boot, but there'no device that would drive them. They can be brought to that state by gpio-hog nodes added under the gpio controller node, see [[https://github.com/jcmvbkbc/linux-xtensa/blob/v6.7/Documentation/devicetree/bindings/gpio/gpio.txt#L202|Documentation/devicetree/bindings/gpio/gpio.txt]] for the details.+GPIO pins may need to be in a specific state after boot, but there may be no device that would drive them. In that case they can be brought to that state by the gpio-hog nodes added under the gpio controller node, see [[https://github.com/jcmvbkbc/linux-xtensa/blob/v6.7/Documentation/devicetree/bindings/gpio/gpio.txt#L202|Documentation/devicetree/bindings/gpio/gpio.txt]] for the details.
