Hi Jean-Christophe,

FYI, there are new compile warnings show up in

commit: 7f46dcb289fd5970296718ce20046792dfbc00a8  ARM: at91: add pinctrl support
config: arm-at91_dt_defconfig # make ARCH=arm at91_dt_defconfig

All warnings:

drivers/pinctrl/pinctrl-at91.c: In function 'at91_pinctrl_probe_dt':
drivers/pinctrl/pinctrl-at91.c:841:12: warning: assignment discards 'const' qualifier from pointer target type [enabled by default]
