2017-04-05mainboard/google/reef: increase trackpad data hold timeAaron Durbin
Even though the i2c spec has no minimum data hold time in fast mode the trackpad vendor indicates 300ns is their minimum. However, the topology of the board uses FET isolation to cross voltage domains. Therefore, the default 300ns which should work isn't reflected on the device side of the voltage isolation circuit. Therefore, increase the data hold time to show an observed data hold time of more than 300ns on the device side.

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.

Add power management type config option that allows mainboards to either: 1. Define a power resource that uses the reset and enable gpios to power on and off the device using _ON and _OFF methods, or 2. Export reset and enable GPIOs in _CRS and _DSD so that the OS can directly toggle the GPIOs as required. GPIO type needs to be updated in drivers_i2c_generic_config to use acpi_gpio type so that it can be used for both the above cases.
