Please move the pin definitions into a more concise one, like so: qup_spi0_default: qup-spi0-default { pins = "gpio0", "gpio1", "gpio2", "gpio3"; function = "qup0"; drive-strength = <6>; bias-disable; }; (hopefully Thunderbird didn't mess up newlines here..) Overall, the patch - while on the large side - looks correct to me. Thanks! Konrad
