Can you elaborate why you think pin muxing is required with > GpioIo/GpioInt resources? How are the pin muxes normally configured in ACPI? All of our GPIOs have a pinmux on them, and so if you want to use the pin for the non-default functionality, you need to configure the mux. Isn't that supposed to happen with the through the pinctrl driver? That is, when the kernel parses the ASL, and it seems a command to configure pin #3 to function #4, it calls the local pinctrl driver to do that? -- Sent by an employee of the Qualcomm Innovation Center, Inc.
