+Subject: [PATCH 1/3] ARM: dts: rename oxnas dts files
+
+Other platforms' device-tree files start with a platform prefix, such as
+sun7i-a20-*.dts or at91-*.dts.
+This naming scheme turns out to be handy when using multi-platform build
+systems such as OpenWrt.
+Prepend oxnas files with their platform prefix to comply with the naming
+scheme already used for most other platforms.

- DT
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-NAND subsystem is being slightly reworked to store ECC details in
-separated fields. In future we'll want to add support for more DT
-properties as specifying every possible setup with a single
-"nand-ecc-mode" is a pretty bad idea.
-To allow this let's add a helper that will support something like
-"nand-ecc-algo" in future. Right now we use it for keeping backward
-compatibility.
