+Subject: [PATCH] BCM270X_DT: Rename Pi Zero W DT files
+
+The downtream Pi Zero W dts file uses the digit 0, whereas upstream
+chose to spell it out - "zero-w". The firmware has, for a long time,
+looked for bcm2708-rpi-zero-w.dtb first before falling back to the
+numerical version. Therefore it is better to follow upstream and
+make the switch to "bcm2708-rpi-zero-w".
+
+At the same time, remove some overrides that duplicate values
+inherited from the shared .dtsi files.
