* dt-binding: arm/cpus.txt: fix dynamic-power-coefficient unitVincent Guittot2018-09-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The unit of dynamic-power-coefficient is described as mW/MHz/uV^2 whereas its usage in the code assumes that unit is uW/MHz/V^2 In drivers/thermal/cpu_cooling.c, the code is : power = (u64)capacitance * freq_mhz * voltage_mv * voltage_mv; do_div(power, 1000000000); which can be summarized as : power (mW) = capacitance * freq_mhz/1000 * (voltage_mv/1000)^2 or power (mW) = (capacitance * freq_mhz * (voltage_mv/1000)^2) / 1000 then power (mW) = power (uW) / 1000 so power (uW) = capacitance * freq_mhz * (voltage_mv/1000)^2 Furthermore, if we test basic values like : voltage_mv = 1000mV = 1V freq_mhz = 1000Mhz The minimum possible power, when dynamic-power-coefficient equals 1, will be with current unit: min power = 1 * 1000 * (1000000)^2 = 10^15 mW which is not realistic With the unit used by the code, the min power is min power = 1 * 1000 * 1^2 = 1000uW = 1mW which is far more realistic Signed-off-by: Vincent Guittot <vincent.guittot@linaro.org> Acked-by: Punit Agrawal <punit.agrawal@arm.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rob Herring <robh@kernel.org>

Another important change is the addition of ARMv7-A based chips in mach-stm32. The older parts in this platform are ARMv7-M based microcontrollers, now they are expanding to general-purpose workloads. The other changes are the usual defconfig updates to enable additional drivers, lesser bugfixes. The largest updates as often are the ongoing OMAP cleanups, but we also have a number of changes for the older PXA and davinci platforms this time. For the Renesas shmobile/r-car platform, some new infrastructure is needed to make the watchdog work correctly. Supporting Multiprocessing on Allwinner A80 required a significant amount of new code, but is not doing anything unexpected" * tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (179 commits) arm: npcm: modify configuration for the NPCM7xx BMC.

| * ARM: sunxi: mc-smp: Use DT enable-method for sun9i A80 SMPChen-Yu Tsai2018-03-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of having an early init function check the machine compatible and installing multi-cluster SMP support for the A80 if it matches, use a new cpu enable-method string. This makes the platform support future proof in case anyone manages to add PSCI support. The original init code for the SMP support is changed into the .prepare_cpus callback in the smp_operations structure. Instead of panicing when resources are missing like on some platforms, our code merely guards against engaging SMP or CPU hotplug and returns an error.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ARM systems may be configured to have cpus with different power/performance characteristics within the same chip. In this case, additional information has to be made available to the kernel (the scheduler in particular) for it to be aware of such differences and take decisions accordingly. Therefore, this patch aims at standardizing cpu capacities device tree bindings for ARM platforms. Bindings define cpu capacity-dmips-mhz parameter, to allow operating systems to retrieve such information from the device tree and initialize related kernel structures, paving the way for common code in the kernel to deal with heterogeneity.

* drivers: firmware: psci: unify enable-method binding on ARM {64,32}-bit systemsSudeep Holla2016-04-261-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | Currently ARM CPUs DT bindings allows different enable-method value for PSCI based systems. On ARM 64-bit this property is required and must be "psci" while on ARM 32-bit systems this property is optional and must be "arm,psci" if present. However, "arm,psci" has always been the compatible string for the PSCI node, and was never intended to be the enable-method. So this is a bug in the binding and not a deliberate attempt at specifying 32-bit differently. This is problematic if 32-bit OS is run on 64-bit system which has "psci" as enable-method rather than the expected "arm,psci". So let's unify the value into "psci" and remove support for "arm,psci" before it finds any users.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds an SMP boot method for the ARM RealView reference designs. We also select HAVE_SMP by default and make it use SMP_ON_UP so we only need to support one single kernel across the RealView reference designs when using DT. The RealViews need to have the SCU (Snoop Control Unit) activated on boot, and this is now done by looking up its address from the device tree and initializing it and counting the available cores. The RealViews boot by using a magic address register in the system controller (SYS_FLAGS) to store the boot address, the ROM will then read this register to the PC when the CPUs are taken out of WFI. This code uses a handle to the syscon regmap to access this register. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

| | | | | | | | | | | | | | | | 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 <linus.walleij@linaro.org> Signed-off-by: Olof Johansson <olof@lixom.net>

* Documentation: DT bindings: add nvidia, tegra132-denver compatible stringPaul Walmsley2015-02-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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
