Subject: [PATCH 508/773] 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.
|
|
