Keep uboot GPIO settings through kernel boot S32G2

Hi,

I'd like to configure a GPIO in u-boot, then tell the kernel to ignore that GPIO during boot. The kernel currently overrides the u-boot settings. I added the specific GPIO to the gpio-reserved-ranges in the DTS but that had no effect. I currently do not have anything in the DTS file to configure this specific GPIO.

Thanks

Hi Gabriel LoDolce

Hope you are doing well

I think you have to disable that gpio in kernal which reconfigs. We suggest you please go with u-boot and kernel community for more details.
