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 ...

arm: nomadik: drop selecting obsolete CLKSRC_NOMADIK_MTU_SCHED_CLOCK

2022-05-03T12:44:21+00:00

Commit 85b6fcadcf66 ("clocksource/drivers/ux500: Drop Ux500 custom SCHED_CLOCK") removes a sched_clock workaround and its corresponding config CLKSRC_NOMADIK_MTU_SCHED_CLOCK. Since then, selecting CLKSRC_NOMADIK_MTU_SCHED_CLOCK in ./arch/arm/mach-nomadik/Kconfig has no effect and ./scripts/checkkconfigsymbols.py warns: CLKSRC_NOMADIK_MTU_SCHED_CLOCK Referencing files: arch/arm/mach-nomadik/Kconfig Simply drop selecting the obsolete CLKSRC_NOMADIK_MTU_SCHED_CLOCK.

ARM: rework endianess selection

2022-04-08T15:20:54+00:00

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

ARM: nomadik: select MFD_SYSCON

Since the Power Management Unit is using syscon to access a set of necessary hardware muxing, let's select MFD_SYSCON for the Nomadik subarchitecture. Signed-off-by: Linus Walleij

ARM: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB

2016-06-03T19:18:13+00:00

This replaces: - "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can now be selected directly. - "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB is now selectable by everyone, so we need not declare our intent to select it. 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".

ARM: use menuconfig for sub-arch menus

2014-06-17T15:09:48+00:00

The System Type menu is getting quite long with platforms and is inconsistent in handling of sub-arch specific options. Tidy up the menu by making platform options a menuconfig entry containing any platform specific config items.

ARM: nomadik: switch to use the Nomadik I2C driver

2013-08-06T22:59:06+00:00

Instead of using bit-banged I2C, let's use the actual I2C driver in the kernel. Since the I2C block may be communicating with things like the PMIC, we need to select it from the Kconfig just like the bit-banged adapter is selected today. The rest of the configuration for this driver can be done from the device tree. Signed-off-by: Linus Walleij
