pinctrl-at91 currently does not support the gpio-groups devicetree property and has no pin-range. Because of this at91 gpios stopped working since patch commit 2ab73c6d8323fa1e ("gpio: Support GPIO controllers without pin-ranges") This was discussed in the patches commit fc328a7d1fcce263 ("gpio: Revert regression in sysfs-gpio (gpiolib.c)") commit 56e337f2cf132632 ("Revert "gpio: Revert regression in sysfs-gpio (gpiolib.c)"") As a workaround manually set pin-range via gpiochip_add_pin_range() until a) pinctrl-at91 is reworked to support devicetree gpio-groups b) another solution as mentioned in commit 56e337f2cf132632 ("Revert "gpio: Revert regression in sysfs-gpio (gpiolib.c)"") is found Signed-off-by: Thomas Blocher <thomas.blocher@ek-dev.de> --- drivers/pinctrl/pinctrl-at91.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) base-commit: c91a7dee0555f6f9d3702d86312382e4c4729d0a
