This is a second spin of the patch set that adds support for the Embedded Controller on an OLPC XO 1.75 machine. OLPC XO 1.75 is a MMP2 based ARM laptop. It plugs into the existing OLPC platform infrastructure, currently used by the x86 based models. The slave mode support for MMP2's SPI controller that the EC is hooked to is now in spi.git's for-4.21 branch. The v1 received a fair number of comments. I've attempted to address all of them, either by fixing things or responding to the v1 review. See the change logs in the individual patches for details. If I've overlooked something then I apologize -- I haven't dealt with a patch set as big as this and I'm struggling to incorporate the feedback in an organized manner. Advice from the more experienced folks around here are welcome. Tested to work on an OLPC XO 1.75 and also tested not to break x86 support with an OLPC XO 1 machine. I don't have a XO 1.5, but it's unlikely this breaks it when XO 1 works. Lubo
