From 3cd31a44e61e2219d730d6b1a4a13c8e15d6e395 Mon Sep 17 00:00:00 2001

Subject: [PATCH] ARM: dts: overlays: Unify overlay CMA handling
Now that we don't have to abuse the kernel command line to change CMA's
size we can clean-up and centralize CMA usage in overlays.
A new file, cma-overlay.dts is created to be used as a standalone
overlay or included on other overlays. All CMA users are converted to
this scheme. Ultimately upstream-overlay.dts is also updated to use the
default CMA size provided by upstream.
