Add the num-cs property to each node. The current driver doesn't read this property but this is useful for downstream user of DTS (FreeBSD for example). Signed-off-by: Emmanuel Vadot --- Changes in v2: * Explain that driver doesn't support this but that it is useful for downstream users of DTS. arch/arm/boot/dts/sun7i-a20.dtsi | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/arch/arm/boot/dts/sun7i-a20.dtsi b/arch/arm/boot/dts/sun7i-a20.dtsi index 94cf5a1c7172..ed21982c81cb 100644 --- a/arch/arm/boot/dts/sun7i-a20.dtsi +++ b/arch/arm/boot/dts/sun7i-a20.dtsi @@ -871,6 +871,7 @@ status = "disabled"; #address-cells = <1>; #size-cells = <0>; + num-cs = 4; }; spi1: spi@01c06000 { @@ -885,6 +886,7 @@ status = "disabled"; #address-cells = <1>; #size-cells = <0>; + num-cs = 1; }; emac: ethernet@01c0b000 { @@ -1037,6 +1039,7 @@ status = "disabled"; #address-cells = <1>; #size-cells = <0>; + num-cs = 1; }; ahci: sata@01c18000 { @@ -1079,6 +1082,7 @@ status = "disabled"; #address-cells = <1>; #size-cells = <0>; + num-cs = 1; }; pio: pinctrl@01c20800 { -- 2.11.0
