Picked patches 1, 2, and 5 to l2-mtd.git. I requested changes to patch 3
and possibly 4. The rest look OK, but I don't want to futz with patch
conflicts on the remaining. Please rebase to l2-mtd.git if/when you
resend.

Typically "simpler" and "reducing the cost of having lots of extra DT
properties" aren't good enough reasons for immediately breaking an
existing DT binding. We usually expect to support both for some period
of time.
