Subject: [PATCH 2/2] ARM: dts: gpio-ranges property is now required
Date: Mon, 29 Nov 2021 10:55:56 +0000 [thread overview]
Message-ID: <20211129105556.675235-3-phil@raspberrypi.com> (raw)
In-Reply-To: <20211129105556.675235-1-phil@raspberrypi.com>
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")
Signed-off-by: Phil Elwell <phil@raspberrypi.com>
