Subject: ARM: dts: gpio-ranges property is now required
From: Phil Elwell <phil@xxxxxxxxxxxxxxx>
commit e8f24c58d1b69ecf410a673c22f546dc732bb879 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")
Fixes: 2ab73c6d8323 ("gpio: Support GPIO controllers without pin-ranges")
