EC21 Quecopen disable PCM to use GPIO

I am developing EC21 and Hardware designed to use GPIO79 and GPIO78. in Quecopen those GPIO used for PCM.
so How to disable PCM to use Pin 26 and 27 as GPIO.

anyone can help me on this problem?

I didn’t find any patch for it.
What you need to do is to modify the linux device tree settings to disable the default feature.
For example you even can modify the mdm9607-pinctrl.dtsi, remove all the gpio78 and gpio79.

I changed those pins to others. they worked

Glad that’s worked out
