git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC driver updates from Arnd Bergmann: "The main addition this time around is the new ARM "SCMI" framework, which is the latest in a series of standards coming from ARM to do power management in a platform independent way. This has been through many review cycles, and it relies on a rather interesting way of using the mailbox subsystem, but in the end I agreed that Sudeep's version was the best we could do after all. Other changes include: - the ARM CCN driver is moved out of drivers/bus into drivers/perf, which makes more sense. Similarly, the performance monitoring portion of the CCI driver are moved the same way and cleaned up a little more. - a series of updates to the SCPI framework - support for the Mediatek mt7623a SoC in drivers/soc - support for additional NVIDIA Tegra hardware in drivers/soc - a new reset driver for Socionext Uniphier - lesser bug fixes in drivers/soc, drivers/tee, drivers/memory, and drivers/firmware and drivers/reset across platforms" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (87 commits) reset: uniphier: add ethernet reset control support for PXs3 reset: stm32mp1: Enable stm32mp1 reset driver dt-bindings: reset: add STM32MP1 resets reset: uniphier: add Pro4/Pro5/PXs2 audio systems reset control reset: imx7: add 'depends on HAS_IOMEM' to fix unmet dependency reset: modify the way reset lookup works for board files reset: add support for non-DT systems clk: scmi: use devm_of_clk_add_hw_provider() API and drop scmi_clocks_remove firmware: arm_scmi: prevent accessing rate_discrete uninitialized hwmon: (scmi) return -EINVAL when sensor information is unavailable amlogic: meson-gx-socinfo: Update soc ids soc/tegra: pmc: Use the new reset APIs to manage reset controllers soc: mediatek: update power domain data of MT2712 dt-bindings: soc: update MT2712 power dt-bindings cpufreq: scmi: add thermal dependency soc: mediatek: fix the mistaken pointer accessed when subdomains are added soc: mediatek: add SCPSYS power domain driver for MediaTek MT7623A SoC soc: mediatek: avoid hardcoded value with bus_prot_mask dt-bindings: soc: add header files required for MT7623A SCPSYS dt-binding dt-bindings: soc: add SCPSYS binding for MT7623 and MT7623A SoC ...

This patch prepares the STM32 machine for the integration of Cortex-A based microprocessor (MPU), on top of the existing Cortex-M microcontroller family (MCU). Since both MCUs and MPUs are sharing common hardware blocks we can keep using ARCH_STM32 flag for most of them.

2016-08-17bus: arm-ccn: Correct required arguments for XP PMU eventsPawel Moll
XP can provide events from two sources: watchpoints, observing traffic on device ports and PMU looking at internal buses. Unfortunately the sysfs definition of the PMU events was requiring port number (instead of bus number) and direction (the buses are unidirectional), as these fields were shared with the watchpoint event. Although it does not introduce a major problem (port can be used as bus alias and direction is simply ignored for XP PMU events), it's better to fix it now, before external tools start depending on this behaviour.

2016-02-19Documentation: arm: update Marvell product listingArnd Bergmann
I'm still getting confused regarding which core specifically is used in which SoC, so I've added some more detail to the Marvell README file. I got most of this from random sources on the internet, so it's possible that some of the information is wrong, but most of it should be pretty obvious. There are a few remaining points I could not find out: * The CPU core in Orion 88F6183 * The difference (if any) between PJ4B-MP and PJ4C * The naming of Feroceon/Jolteon/Flareon/Sheeva/Mohawk/PJ1/PJ4 is still confusing, as they tend to overlap. Signed-off-by: Arnd Bergmann <arnd@arndb.de> [Thomas: - move Armada SP out from the EBU family into its own "Storage" family. This chip is indeed not part of the EBU family. - fixed the URL for the Armada SP information, since the link of the original patch no longer existed - explicitly indicate that there is no support in upstream for the Armada SP - indent the "Core: " description for the Armada XP to be clearly under the Armada XP category, so that it is clear it applies to Armada XP only, and not other cores of the EBU family.] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Gregory CLEMENT <gregory.clement@free-electrons.com>

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC multiplatform code updates from Arnd Bergmann: "This branch is the culmination of 5 years of effort to bring the ARMv6 and ARMv7 platforms together such that they can all be enabled and boot the same kernel. It has been a tremendous amount of cleanup and refactoring by a huge number of people, and creation of several new (and major) subsystems to better abstract out all the platform details in an appropriate manner. The bulk of this branch is a large patchset from Arnd that brings several of the more minor and older platforms we have closer to multiplatform support. Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview Much of this is moving around header files from old mach directories, but there are also some cleanup patches of debug_ll (lowlevel debug per-platform options) and other parts. Linus Walleij also has some patchs to clean up the older ARM Realview platforms by finally introducing DT support, and Rob Herring has some for ARM Versatile which is now DT-only. Both of these platforms are now multiplatform. Finally, a couple of patches from Russell for Dove PMU, and a fix from Valentin Rothberg for Exynos ADC, which were rebased on top of the series to avoid conflicts" * tag 'armsoc-multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (75 commits) ARM: realview: don't select SMP_ON_UP for UP builds ARM: s3c: simplify s3c_irqwake_{e,}intallow definition ARM: s3c64xx: fix pm-debug compilation iio: exynos-adc: fix irqf_oneshot.cocci warnings ARM: realview: build realview-dt SMP support only when used ARM: realview: select apropriate targets ARM: realview: clean up header files ARM: realview: make all header files local ARM: no longer make CPU targets visible separately ARM: integrator: use explicit core module options ARM: realview: enable multiplatform ARM: make default platform work for NOMMU ARM: debug-ll: move DEBUG_LL_UART_EFM32 to correct Kconfig location ARM: defconfig: use correct debug_ll settings ARM: versatile: convert to multi-platform ARM: versatile: merge mach code into a single file ARM: versatile: switch to DT only booting and remove legacy code ARM: versatile: add DT based PCI detection ARM: pxa: mark ezx structures as __maybe_unused ARM: pxa: mark raumfeld init functions as __maybe_unused ...

bootargs Currently kernel crash randomly when K2L EVM is booted without clk_ignore_unused in the bootargs. This workaround is not needed on other K2 devices such as K2HK and K2E and with this fix, we can remove the workaround altogether. netcp driver on K2L uses linked ram on OSR (On chip Static RAM) and requires the clock to this peripheral enabled for proper functioning. This is the reason for the kernel crash. So add the clock node to fix this issue. While at it, remove the workaround documentation as well. With the fix applied, clk_summary dump shows the clock to OSR enabled. cat /sys/kernel/debug/clk/clk_summary ------cut-------------- tcp3d-1 0 0 399360000 0 0 tcp3d-0 0 0 399360000 0 0 osr 1 1 399360000 0 0 fftc-0 0 0 399360000 0 0 -----cut---------------- Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: Santosh Shilimkar <ssantosh@kernel.org>
