2015-06-15mfd: cros_ec: add proto v3 skeletonStephen Barber1-36/+303
Add support in cros_ec.c to handle EC host command protocol v3. For v3+, probe for maximum shared protocol version and max request, response, and passthrough sizes. For now, this will always fall back to v2, since there is no bus-specific code for handling proto v3 packets.

2015-06-15mfd: cros_ec: Move protocol helpers out of the MFD driverJavier Martinez Canillas1-0/+115
The MFD driver should only have the logic to instantiate its child devices and setup any shared resources that will be used by the subdevices drivers. The cros_ec MFD is more complex than expected since it also has helpers to communicate with the EC. So the driver will only get more bigger as other protocols are supported in the future. So move the communication protocol helpers to its own driver as drivers/platform/chrome/cros_ec_proto.c.
