Instead, each pin gets a different node and then pinctrl-0 has a list of phandles to the different nodes. qcom maintainers may have more input here. Also, this should really go into a different section than here. I thought the style was to have a 'board specific' pinctrl section. > +}; > + > &pmk8350_vadc { > pmr735a_die_temp { > reg = <PMR735A_ADC7_DIE_TEMP>;
