Hi,
We use a 3rd party 820 SOM with a base board we designed.
I looked at this post, and added the following code to msm8996-pins.dtsi:
&msmgpio {
pinmux {
function = "gpio";
pins = "gpio21"; // gp21 is pull-down by default.
pinconf {
pins = "gpio21";
bias-pull-up; //bias-disable;
};
...
but it doesn’t seem to do anything. Is the code correct?
It could be a HW issue so I just would like to determine if it is our board, or the device tree is not correct.
Thanks,
