Note that this relies on a few outstanding changes: * Needs "cros-ec-keyboard.dtsi" in order to compile properly. See (ARM: dts: Create a cros-ec-keyboard fragment) at . * Needs (mfd: cros_ec: spi: Fix end of transfer on devices with no spi-msg-delay) from this series to work properly. * Needs (spi: s3c64xx: fix broken "cs_gpios" usage in the driver) and (spi: s3c64xx: for DT platofrms always get the chipselect info from DT node) to work properly and match the documented bindings.
