[PATCH] ARM: dts nuvoton: Add EDAC node

[PATCH] ARM: dts nuvoton: Add EDAC node

[William A. Kennington III]

From: "William A. Kennington III" <wak@google.com>

We have the driver support code, now we just need to expose the device
node which can export the EDAC properties for the system memory
controller. Tested on real hardware to verify that error counters show
up.

Hi William,

As a bit of a nit, you missed the `:` after `dts` in the patch subject.

This compatible string doesn't look right to me. Are you sure?
