From f45200b67ea381d784dca8088dc31cbf06bd17cc Mon Sep 17 00:00:00 2001 From: Lubomir Rintel Date: Sat, 18 Jul 2020 22:50:08 +0200 Subject: [PATCH] ARM: dts: mmp2-olpc-xo-1-75: Delete #address-cells from ssp3 On the XO-1.75, this node represents a bus interface that operates in slave mode and thus is only able to accommodate a single subnode; no address cells are necessary. The Documentation/devicetree/bindings/spi/spi-controller.yaml binding prefers that we drop the property instead of setting it to zero. This fixes a DT validation error: arch/arm/boot/dts/mmp2-olpc-xo-1-75.dt.yaml: spi@d4037000: { ... } is valid under each of {'required': ['spi-slave']}, {'required': ['#address-cells']} We also need to drop #size-cells: arch/arm/boot/dts/mmp2-olpc-xo-1-75.dt.yaml: spi@d4037000: '#address-cells' is a dependency of '#size-cells' Link: https://lore.kernel.org/r/20200718205019.184927-3-lkundrak@v3.sk Signed-off-by: Lubomir Rintel Signed-off-by: Arnd Bergmann --- arch/arm/boot/dts/mmp2-olpc-xo-1-75.dts | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/arch/arm/boot/dts/mmp2-olpc-xo-1-75.dts b/arch/arm/boot/dts/mmp2-olpc-xo-1-75.dts index 02f4005a654b..392f546f7915 100644 --- a/arch/arm/boot/dts/mmp2-olpc-xo-1-75.dts +++ b/arch/arm/boot/dts/mmp2-olpc-xo-1-75.dts @@ -221,7 +221,8 @@ }; &ssp3 { - #address-cells = <0>; + /delete-property/ #address-cells; + /delete-property/ #size-cells; spi-slave; status = "okay"; ready-gpio = <&gpio 125 GPIO_ACTIVE_HIGH>; -- 2.11.0
