    Subject[PATCH stable 5.4 7/7] ARM: dts: gpio-ranges property is now required
    Date
    From: Phil Elwell <phil@raspberrypi.com>

    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")

    Link: https://lore.kernel.org/r/20220104170247.956760-1-linus.walleij@linaro.org
    Fixes: 2ab73c6d8323 ("gpio: Support GPIO controllers without pin-ranges")
    Fixes: 266423e60ea1 ("pinctrl: bcm2835: Change init order for gpio hogs")
