Merge tag 'arm-dts-mv-for-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux into soc/dt
ARM: dts: Move .dts files to vendor sub-directories The arm dts directory has grown to 1559 boards which makes it a bit unwieldy to maintain and use. Past attempts stalled out due to plans to move .dts files out of the kernel tree. Doing that is no longer planned (any time soon at least), so let's go ahead and group .dts files by vendors. This move aligns arm with arm64 .dts file structure. * tag 'arm-dts-mv-for-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: ARM: dts: Move .dts files to vendor sub-directories kbuild: Support flat DTBs install ARM: dts: Add .dts files missing from the build ARM: dts: allwinner: Use quoted #include Link: https://lore.kernel.org/r/20230621185025.GA3197738-robh@kernel.org Signed-off-by: Arnd Bergmann <arnd@arndb.de>
