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. + +Signed-off-by: Phil Elwell <phil@raspberrypi.org> +--- + arch/arm/boot/dts/Makefile | 2 +- + .../boot/dts/{bcm2708-rpi-0-w.dts => bcm2708-rpi-zero-w.dts} | 5 ----- + 2 files changed, 1 insertion(+), 6 deletions(-) + rename arch/arm/boot/dts/{bcm2708-rpi-0-w.dts => bcm2708-rpi-zero-w.dts} (97%) + +--- a/arch/arm/boot/dts/Makefile ++++ b/arch/arm/boot/dts/Makefile +@@ -4,7 +4,7 @@ dtb-$(CONFIG_ARCH_BCM2835) += \ + bcm2708-rpi-b.dtb \ + bcm2708-rpi-b-plus.dtb \ + bcm2708-rpi-cm.dtb \ +- bcm2708-rpi-0-w.dtb \ ++ bcm2708-rpi-zero-w.dtb \ + bcm2709-rpi-2-b.dtb \ + bcm2710-rpi-3-b.dtb \ + bcm2710-rpi-3-b-plus.dtb \ +--- a/arch/arm/boot/dts/bcm2708-rpi-0-w.dts ++++ /dev/null +@@ -1,167 +0,0 @@ +-/dts-v1/;
