Subject: [PATCH 5.4 09/11] ARM: dts: gpio-ranges property is now required

From: Phil Elwell <phil@...pberrypi.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")
