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.

Hi, Nicolas,

If all good with this patches please update the SHA1 on "Depends-on"
tag.

Yes, sure. I did it on the "fixes" branch queued for 5.18.

Thanks, best regards,
Nicolas
