[PATCH 5.14 319/334] ARM: dts: at91: add pinctrl-{names, 0} for all gpios

From: Greg Kroah-Hartman
Date: Mon Sep 13 2021 - 10:49:50 EST


From: Claudiu Beznea <claudiu.beznea@xxxxxxxxxxxxx>

commit bf781869e5cf3e4ec1a47dad69b6f0df97629cbd upstream.

Add pinctrl-names and pinctrl-0 properties on controllers that claims to
use pins to avoid failures due to
commit 2ab73c6d8323 ("gpio: Support GPIO controllers without pin-ranges")
and also to avoid using pins that may be claimed my other IPs.

Fixes: b7c2b6157079 ("ARM: at91: add Atmel's SAMA5D3 Xplained board")
Fixes: 1e5f532c2737 ("ARM: dts: at91: sam9x60: add device tree for soc and board")
Fixes: 38153a017896 ("ARM: at91/dt: sama5d4: add dts for sama5d4 xplained board")
