dtc has new checks for SPI buses. The rk3036 dts file has a node named spi' which causes false positive warnings. As the node is a pinctrl child node, change the node name to be 'spi-pins' to fix the warnings. arch/arm/boot/dts/rk3036-evb.dtb: Warning (spi_bus_bridge): /pinctrl/spi: incorrect #address-cells for SPI bus arch/arm/boot/dts/rk3036-kylin.dtb: Warning (spi_bus_bridge): /pinctrl/spi: incorrect #address-cells for SPI bus arch/arm/boot/dts/rk3036-evb.dtb: Warning (spi_bus_bridge): /pinctrl/spi: incorrect #size-cells for SPI bus arch/arm/boot/dts/rk3036-kylin.dtb: Warning (spi_bus_bridge): /pinctrl/spi: incorrect #size-cells for SPI bus Cc: Heiko Stuebner <heiko@xxxxxxxxx> Cc: linux-rockchip@xxxxxxxxxxxxxxxxxxx Signed-off-by: Rob Herring <robh@xxxxxxxxxx> --- Please apply to the sub-arch tree.
