I see things like:
.../sdm845-cheza.dtsi: pinctrl-0 = <&qup_uart6_4pin>;
...before your patch that would get the bias/drive strength from the
SoC dtsi, right? After your patch, you've removed it from the dtsi but
not added it to the board. ...so I think it's a net change. Did I mess
up / miss something?
