[PATCH v2 2/2] ARM: dts: gpio-ranges property is now required

From: Phil Elwell <hidden>
Date: 2021-12-06 09:22:57
Also in: linux-gpio
Subsystem: the rest · Maintainer: Linus Torvalds

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")

Fixes: 2ab73c6d8323 ("gpio: Support GPIO controllers without pin-ranges")
