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 ...
2022-05-03arm: nomadik: drop selecting obsolete CLKSRC_NOMADIK_MTU_SCHED_CLOCKLukas Bulwahn1-1/+0

2022-04-08ARM: rework endianess selectionArnd Bergmann1-0/+1
Choosing big-endian vs little-endian kernels in Kconfig has not worked correctly since the introduction of CONFIG_ARCH_MULTIPLATFORM a long time ago. The problems is that CONFIG_BIG_ENDIAN depends on ARCH_SUPPORTS_BIG_ENDIAN, which can set by any one platform in the config, but would actually have to be supported by all of them. This was mostly ok for ARMv6/ARMv7 builds, since these are BE8 and tend to just work aside from problems in nonportable device drivers. For ARMv4/v5 machines, CONFIG_BIG_ENDIAN and CONFIG_ARCH_MULTIPLATFORM were never set together, so this was disabled on all those machines except for IXP4xx. As IXP4xx can now become part of ARCH_MULTIPLATFORM, it seems better to formalize this logic: all ARMv4/v5 platforms get an explicit dependency on being either big-endian (ixp4xx) or little-endian (the rest). We may want to fix ixp4xx in the future to support both, but it does not work in LE mode at the moment. For the ARMv6/v7 platforms, there are two ways this could be handled a) allow both modes only for platforms selecting 'ARCH_SUPPORTS_BIG_ENDIAN' today, but only LE mode for the others, given that these were added intentionally at some point. b) allow both modes everwhere, given that it was already possible to build that way by e.g. selecting ARCH_VIRT, and that the list is not an accurate reflection of which platforms may or may not work. Out of these, I picked b) because it seemed slighly more logical to me. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

When ordering the symbols the following rationale was used: if the selects were in alphabetical order, I moved select GPIOLIB to be in alphabetical order, but if the selects were not maintained in alphabetical order, I just replaced "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

2013-10-07Merge branch 'clk-of-init-v2_for-3.13' of ↵Olof Johansson1-36/+0
https://github.com/shesselba/linux-dove into next/cleanup From Sebastian Hasselbarth: This is a patch set based on an RFC [1][2] sent earlier to provide a common arch/arm init for DT clock providers. Currently, the call to of_clk_init(NULL) to initialize DT clock providers is spread among several mach-dirs. Since most machs require DT clocks initialized before timers, no initcall can be used. By adding of_clk_init(NULL) to arch/arm time_init(), we can remove all mach-specific .init_time hooks that basically called of_clk_init and clocksource_of_init. In contrast to the RFC version, of_clk_init(NULL) is now only called if no custom .init_time callback is set. This allows some machs to still call clock init themselves, as not all can be converted now. Therefore, this patch sets drops conversion of mach-mvebu and mach-zynq. New machs that were introduced with v3.12-rc1 are also converted, except mach-u300 that requires clocks before irqs. * 'clk-of-init-v2_for-3.13' of https://github.com/shesselba/linux-dove: (29 commits) ARM: vt8500: remove custom .init_time hook ARM: vexpress: remove custom .init_time hook ARM: tegra: remove custom .init_time hook ARM: sunxi: remove custom .init_time hook ARM: sti: remove custom .init_time hook ARM: socfpga: remove custom .init_time hook ARM: rockchip: remove custom .init_time hook ARM: prima2: remove custom .init_time hook ARM: nspire: remove custom .init_time hook ARM: nomadik: remove custom .init_time hook ARM: mxs: remove custom .init_time hook ARM: kirkwood: remove custom .init_time hook ARM: imx: remove custom .init_time hook ARM: highbank: remove custom .init_time hook ARM: exynos: remove custom .init_time hook ARM: dove: remove custom .init_time hook ARM: bcm2835: remove custom .init_time hook ARM: bcm: provide common arch init for DT clocks ARM: call of_clk_init from default time_init handler ARM: vt8500: prepare for arch-wide .init_time callback ...

This adds the FSMC NAND driver and flash partitions to the Nomadik device tree. The only compatible string accepted by this driver is currently "st,spear600-fsmc-nand" which is inappropriate for this system, so this patch adds the compatible value "stericsson,fsmc-nand" as well.

2013-01-28ARM: nomadik: move remaining PrimeCells to device treeLinus Walleij1-2/+9
The two remaining PrimeCells, RNG and RTC, are migrated to the device tree for device tree boot. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-01-28ARM: nomadik: move pin maps to cpu fileLinus Walleij2-45/+44
Move the pinctrl maps over to the CPU file and register them right before the pin controller itself. This way the pinmaps will also benefit the device tree boot. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-01-28ARM: nomadik: initial devicetree supportLinus Walleij4-1/+87
Support basic device tree boot on the Nomadik. Implement the support in the cpu file with the intent of deleting the board files later. At this stage IRQ controllers, system timer, l2x0 cache, UARTs and thus console boot is fully functional. Patch out the code adding devices by initcalls for now so as not to disturb the boot.

2013-01-28ARM: nomadik: move last custom calls to pinctrlLinus Walleij2-12/+9
The I2C pins were still set up using custom nmk_* calls, move these to use the pinctrl mapping table instead. There was also a remaining call to turn the Ethernet pin to GPIO, and this is now done implicitly by the GPIO-to-pinctrl range translation calls.

into next/cleanup From Rob Herring: Initial irqchip init infrastructure and GIC and VIC clean-ups This creates irqchip initialization infrastructure from Thomas Petazzoni. The VIC and GIC irqchip code is moved to drivers/irqchips and adapted to use the new infrastructure.
