commit c8013355ead68dce152cf426686f8a5f80d88b40 upstream
Since [1], added in 5.7, the absence of a gpio-ranges property has prevented GPIOs from being restored to inputs when released. Add those properties for BCM283x and BCM2711 devices.
[1] commit 2ab73c6d8323 ("gpio: Support GPIO controllers without pin-ranges")
