ARM: dts: vf610-bk4: fix incorrect #address-cells for dspi3
The dspi3 is used as slave controller on vf610-bk4, and the default '#address-cells = <1>;' setting in vfxxx.dtsi causes the following DTC warning. DTC arch/arm/boot/dts/vf610-bk4.dtb ../arch/arm/boot/dts/vfxxx.dtsi:550.24-563.6: Warning (spi_bus_bridge): /soc/aips-bus@40080000/spi@400ad000: incorrect #address-cells for SPI bus also defined at ../arch/arm/boot/dts/vf610-bk4.dts:107.8-119.3 arch/arm/boot/dts/vf610-bk4.dtb: Warning (spi_bus_reg): Failed prerequisite 'spi_bus_bridge' For spi device used as slave controller, '#address-cells' should be 0. Let's overwrite the property in vf610-bk4.dts to fix the warning. Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
