2019-05-20Platform: OLPC: Add XO-1.75 EC driverLubomir Rintel
It's based off the driver from the OLPC kernel sources. Somewhat modernized and cleaned up, for better or worse. Modified to plug into the olpc-ec driver infrastructure (so that battery interface and debugfs could be reused) and the SPI slave framework.
