The objective is that it will be able to support the OLPC XO 1.75 embedded controller that is a SPI master talking to a MMP2 SOC with an extra "ready" signal for handshaking. The patches have been submitted previously along with DT support for the controller which has already been accepted, hence the "v3". These are the remaining ones. Reviewed/Ack-ed by tags have been collected. Other changes to the pataches are described in the respective messages. The EC driver itself is being reviewed in a separate patch set. Verified on a OLPC XO 1.75 machine. Thanks to everyone who kindly provided feedback to make the patch set better. Thank you, Lubo
