2017-11-14mb/google/eve: Remove ACPI control of touchscreen powerDuncan Laurie
Change the touchscreen power control back to coreboot instead of under the ACPI _ON/_OFF methods, and switch the TOUCHSCREEN_STOP_L pin back to an output. This reverts previous changes to touchscreen GPIOs that were made to get back to a known good/working state. Having ACPI control these pins was resulting in a small percentage of touchscreen not being discovered at boot. This platform is not intending to use S0ix so the ACPI control is not needed. BUG=b:63718744 TEST=manual testing on Eve devices.

2017-10-09skylake mainboards: Use PAD_CFG_GPI_GPIO_DRIVER instead of PAD_CFG_GPIFurquan Shaikh
Change 1760cd3e (soc/intel/skylake: Use common/block/gpio) updated all skylake boards to use common gpio driver. Common gpio code defines PAD_CFG_GPI without GPIO_DRIVER ownership. However, for skylake PAD_CFG_GPI set GPIO_DRIVER ownership by default. This resulted in Linux kernel failing to configure all GPIO IRQs since the ownership was not set correctly. (Observed error in dmesg: "genirq: Setting trigger mode 3 for irq 201 failed (intel_gpio_irq_type+0x0/0x110)") This change fixes the above issue by replacing all uses of PAD_CFG_GPI in skylake mainboards to PAD_CFG_GPI_GPIO_DRIVER. BUG=b:67507004 TEST=Verified on soraka that the genirq error is no longer observed in dmesg. Also, cat /proc/interrupts has the interrupts configured correctly.

2017-02-20google/eve: Fix FPC supportDuncan Laurie
Currently UART0 GPIOs are being put into native mode during FSP-S stage, so have ramstage re-configure them back to regular GPIO mode. GPP_C8 does not seem to be functioning properly when routed to the APIC, possibly due to the UART0 being enabled even though it is unused, which is required because UART0 is PCI 1e.0 and so must be present for other 1e.x functions to be enumerated. Instead, use this pin as a GPIO interrupt so it will be routed through the GPIO controller at IRQ 14. GPP_C9 was inverted and was only working because the pin was being re-configured in FSP-S. Also export the reset gpio as a device property so it can be used by the kernel driver, which will stop it from complaining at boot.
