Subject: ARM: dts: at91: fix pinctrl phandles
Git-commit: 0c640d9544d0109da3889d71ae77301e556db977
Patch-mainline: v5.18-rc5
References: git-fixes
Commit bf781869e5cf ("ARM: dts: at91: add pinctrl-{names, 0} for all
gpios") introduces pinctrl phandles for pins used by individual
controllers to avoid failures due to commit 2ab73c6d8323 ("gpio:
Support GPIO controllers without pin-ranges"). For SPI controllers
available on SAMA5D4 and SAMA5D3 some of the pins are defined in
SoC specific dtsi on behalf of pinctrl-0. Adding extra pinctrl phandles
on board specific dts also on behalf of pinctrl-0 overwrite the pinctrl-0
phandle specified in SoC specific dtsi. Thus add the board specific
pinctrl to pinctrl-1.
Fixes: bf781869e5cf ("ARM: dts: at91: add pinctrl-{names, 0} for all gpios")
Depends-on: 5c8b49852910 ("ARM: dts: at91: sama5d4_xplained: fix pinctrl phandle name")
