Subject: [PATCH 1/2] ARM: dts: at91: add pinctrl-{names, 0} for all gpios
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")
Signed-off-by: Claudiu Beznea <claudiu.beznea@...rochip.com>
