ARM: ux500: add an SMP enablement type and move cpu nodes

2015-08-06T08:10:34Z

The "cpus" node cannot be inside the "soc" node, while this works for the CoreSight blocks, the early boot code will look for "cpus" directly under the root node, so this is a hard convention. So move the CPU nodes. Augment the "reg" property to match what is actually in the hardware: 0x300 and 0x301 respectively. Then add an SMP enablement type to be used by the SMP init code, "ste,dbx500-smp". Signed-off-by: Linus Walleij Signed-off-by: Olof Johansson

ARM: sun8i: Add SMP support for the Allwinner A23

Documentation: DT bindings: add nvidia, tegra132-denver compatible string

2015-02-04T02:43:49Z

Add a compatible string for the NVIDIA Denver CPU to the ARM CPU DT binding documentation file. The primary objective here is to keep checkpatch.pl from warning when the compatible string is used in an SoC DT file, per: http://marc.info/?l=linux-tegra&m=142201349727836&w=2 This second version changes the string from "nvidia,denver" to "nvidia,tegra132-denver" to more precisely describe the revision of the Denver CPU complex that is present in the Tegra132 SoC.

ARM: rockchip: add option to access the pmu via a phandle in smp_operations

2014-11-05T21:18:36Z

Makes it possible to define a rockchip,pmu phandle in the cpus node directly referencing the pmu syscon instead of searching for specific compatible. The old way of finding the pmu stays of course available. Signed-off-by: Kever Yang Tested-by: Kevin Hilman Signed-off-by: Heiko Stuebner

Pull ARM64 SoC changes from Arnd Bergmann: "Starting with 3.18, we are merging SoC-specific changes for arm64 through the arm-soc tree, like we have been doing for arm32. This time, there is only one set of changes, adding support for the Cavium "Thunder" Soc family. Since the changes are relatively small, this includes Kconfig, defconfig and DT changes. If all goes well, we will never require adding actual C source code for platform support in arm64, given that the architecture is more clearly defined and we have moved out a lot of the platform specifics into device drivers for arm32 already" * tag 'arm64-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: arm64, defconfig: Enable Cavium Thunder SoC in defconfig arm64, thunder: Add Kconfig option for Cavium Thunder SoC Family arm64, thunder: Document devicetree bindings for Cavium Thunder SoC arm64, thunder: Add initial dts for Cavium Thunder SoC

Documentation: arm: define DT idle states bindings

2014-09-12T09:48:55Z

ARM based platforms implement a variety of power management schemes that allow processors to enter idle states at run-time. The parameters defining these idle states vary on a per-platform basis forcing the OS to hardcode the state parameters in platform specific static tables whose size grows as the number of platforms supported in the kernel increases and hampers device drivers standardization. Therefore, this patch aims at standardizing idle state device tree bindings for ARM platforms. Bindings define idle state parameters inclusive of entry methods and state latencies, to allow operating systems to retrieve the configuration entries from the device tree and initialize the related power management drivers, paving the way for common code in the kernel to deal with idle states and removing the need for static data in current and previous kernel versions. ARM64 platforms require the DT to define an entry-method property for idle states. On system implementing PSCI as an enable-method to enter low-power states the PSCI CPU suspend method requires the power_state parameter to be passed to the PSCI CPU suspend function. This parameter is specific to a power state and platform specific, therefore must be provided by firmware to the OS in order to enable proper call sequence. Thus, this patch also adds a property in the PSCI bindings that describes how the PSCI CPU suspend power_state parameter should be defined in DT in all device nodes that rely on PSCI CPU suspend method usage.
