Merge tag 'arm-multiplatform-5.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARMv4T/v5 multiplatform support from Arnd Bergmann: "This series has been 12 years in the making, it mostly finishes the work that was started with the founding of Linaro to clean up platform support in the kernel. The largest change here is a cleanup of the omap1 platform, which is the final ARM machine type to get converted to the common-clk subsystem. All the omap1 specific drivers are now made independent of the mach/*.h headers to allow the platform to be part of a generic ARMv4/v5 multiplatform kernel. The last bit that enables this support is still missing here while we wait for some last dependencies to make it into the mainline kernel through other subsystems. The s3c24xx, ixp4xx, iop32x, ep93xx and dove platforms were all almost at the point of allowing multiplatform kernels, this work gets completed here along with a few additional cleanup. At the same time, the s3c24xx and s3c64xx are now deprecated and expected to get removed in the future. The PXA and OMAP1 bits are in a separate branch because of dependencies. Once both branches are merged, only the three Intel StrongARM platforms (RiscPC, Footbridge/NetWinder and StrongARM1100) need separate kernels, and there are no plans to include these" * tag 'arm-multiplatform-5.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (61 commits) ARM: ixp4xx: Consolidate Kconfig fixing issue ARM: versatile: Add missing of_node_put in dcscb_init ARM: config: Refresh IXP4xx config after multiplatform ARM: omap1: add back omap_set_dma_priority() stub ARM: omap: fix missing declaration warnings ARM: omap: fix address space warnings from sparse ARM: spear: remove include/mach/ subdirectory ARM: davinci: remove include/mach/ subdirectory ARM: omap2: remove include/mach/ subdirectory integrator: remove empty ap_init_early() ARM: s3c: fix include path MAINTAINERS: omap1: Add Janusz as an additional maintainer ARM: omap1: htc_herald: fix typos in comments ARM: OMAP1: fix typos in comments ARM: OMAP1: clock: Remove noop code ARM: OMAP1: clock: Remove unused code ARM: OMAP1: clock: Fix UART rate reporting algorithm ARM: OMAP1: clock: Fix early UART rate issues ARM: OMAP1: Prepare for conversion of OMAP1 clocks to CCF ARM: omap1: fix build with no SoC selected ...
