2016-06-09skylake: gpio: Add support for setting 1.8V tolerantDuncan Laurie
Add the voltage tolerance GPIO attribute for configuring I2C/I2S buses that are at 1.8V. This is currently done by passing in a value to FSP but it is needed earlier than FSP if the I2C bus is used in verstage. This does not remove the need for the FSP input parameter, that is still required so FSP doesn't disable what has been set in coreboot. The mainboards that are affected are updated in this commit. This was tested by exercising I2C transactions to the 1.8V codec while in verstage on the google/chell mainboard.

2015-10-27google/glados: csme: program sml gpios for csme power gatingArchana Patni
For SMT controllers to power gate, all SMT/SMS clock, data and alert signals should be inactive. The SML0 blocks are not used for any functional purposes and are not configured in the GPIO tables. SMT hardware will not allow the blocks to be power gated in this scenario. The SML* pins are now configured as GPIOs - input and deep. With this change, the SMT blocks are properly power gating.

2015-08-14glados: make EC_SCI_L workAaron Durbin
In order for the EC_SCI_L to work the GPE0 route needs to be set along w/ the GPE event for the EC. As the GPE0 route is dynamic the EC_SCI_GPI needs to be set along with the route so everything lines up. In this case, the GPE0 route is set to the defaults such that GPP_C, GPP_D, and GPP_E are routed to GPE0 block 0, 1, and 2, respectively. This works out for glados because the EC_SCI_L is connected to GPP_E16. BUG=chrome-os-partner:43778 BRANCH=None TEST=Built and booted glados.
