![]() 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> |

README
Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
