2017-01-29i2c/generic: Allow GPIOs to be put in _CRS and PowerResource in ACPIFurquan Shaikh
Linux kernel expects that power management with ACPI should always be handled using PowerResource. However, some kernel drivers (e.g. ELAN touchscreen) check to see if reset gpio is passed in by the BIOS to decide whether the device loses power in suspend. Thus, until the kernel has a better way for drivers to query if device lost power in suspend, we need to allow passing in of GPIOs via _CRS as well as exporting PowerResource to control power to the device. Update mainboards to export reset GPIO as well as PowerResource for ELAN touchscreen device. BUG=chrome-os-partner:62311,chrome-os-partner:60194 BRANCH=reef TEST=Verified that touchscreen works on power-on as well as after suspend-resume.

2017-01-24mainboard/intel/leafhill: initial leafhill board changesBrenton Dong
This commit makes the initial changes to support the Intel Leaf Hill CRB with Apollo Lake silicon. Memory parameters and some GPIOs are set. The google/reef directory is used as a template, and the same IFWI stitching process as reef is used to generate a bootable image. Apollo Lake silicon requires a boot media region called IFWI which includes assets such as CSE firmware, PMC microcode, CPU microcode, and boot firmware.
