Also, none of the other labels have a "state" suffix and the other active-low pin node names have a "-n" suffix. So I believe this should be hall_int_n: hall-int-n-state for consistency. > + pins = "gpio107"; > + function = "gpio"; > + Newline not needed (nor used in the other nodes). > + input-enable; > + bias-disable; > + }; > + > qup0_i2c4_default: qup0-i2c4-default-state { > pins = "gpio171", "gpio172"; > function = "qup4"; Looks good otherwise and appears to work as intended: Reviewed-by: Johan Hovold <johan+linaro@kernel.org> Tested-by: Johan Hovold <johan+linaro@kernel.org> Johan
