See, for instance, "qup_spi0_default" where we configure 4 pins together. Then you don't need so many separate nodes to add. Also: pinconf is nearly always done in board files unless you truly have a reason to believe that it would be the same for every board. > + pri_mi2s_mclk_active: pri-mi2s-mclk-active { > + pinmux { > + pins = "gpio57"; > + function = "lpass_ext"; > + }; > + > + pinconf { > + pins = "gpio57"; > + drive-strength = <8>; > + bias-pull-up; > + }; > + }; > + > sdc1_on: sdc1-on { > pinconf-clk { > pins = "sdc1_clk"; -Doug
