Mika Westerberg c538b94367 pinctrl: intel: Only restore pins that are used by the driver ... Dell XPS 13 (and maybe some others) uses a GPIO (CPU_GP_1) during suspend to explicitly disable USB touchscreen interrupt. This is done to prevent situation where the lid is closed the touchscreen is left functional. The pinctrl driver (wrongly) assumes it owns all pins which are owned by host and not locked down. It is perfectly fine for BIOS to use those pins as it is also considered as host in this context. What happens is that when the lid of Dell XPS 13 is closed, the BIOS configures CPU_GP_1 low disabling the touchscreen interrupt. During resume we restore all host owned pins to the known state which includes CPU_GP_1 and this overwrites what the BIOS has programmed there causing the touchscreen to fail as no interrupts are reaching the CPU anymore. Fix this by restoring only those pins we know are explicitly requested by the kernel one way or other.
