Hi Bartosz

What this series does is show all the different parts are now
available, and can be reviewed as a whole. Once that review is
completed, merging in parts then becomes possible.

It looks like you could probably merge the nvmem, mtd and net parts
independently via there maintainers for 4.20, since i don't think
there are any dependencies. The arm-soc changes in 4.21, and the
removal of the platform data in 4.22?
