Pull ARM SoC platform updates from Olof Johansson: "SoC changes, a substantial part of this is cleanup of some of the older platforms that used to have a bunch of board files. In particular: - Remove non-DT i.MX platforms that haven't seen activity in years, it's time to remove them. - A bunch of cleanup and removal of platform data for TI/OMAP platforms, moving over to genpd for power/reset control (yay!) - Major cleanup of Samsung S3C24xx and S3C64xx platforms, moving them closer to multiplatform support (not quite there yet, but getting close). There are a few other changes too, smaller fixlets, etc. For new platform support, the primary ones are: - New SoC: Hisilicon SD5203, ARM926EJ-S platform. - Cpufreq support for i.MX7ULP" * tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (121 commits) ARM: mstar: Select MStar intc ARM: stm32: Replace HTTP links with HTTPS ones ARM: debug: add UART early console support for SD5203 ARM: hisi: add support for SD5203 SoC ARM: omap3: enable off mode automatically clk: imx: imx35: Remove mx35_clocks_init() clk: imx: imx31: Remove mx31_clocks_init() clk: imx: imx27: Remove mx27_clocks_init() ARM: imx: Remove unused definitions ARM: imx35: Retrieve the IIM base address from devicetree ARM: imx3: Retrieve the AVIC base address from devicetree ARM: imx3: Retrieve the CCM base address from devicetree ARM: imx31: Retrieve the IIM base address from devicetree ARM: imx27: Retrieve the CCM base address from devicetree ARM: imx27: Retrieve the SYSCTRL base address from devicetree ARM: s3c64xx: bring back notes from removed debug-macro.S ARM: s3c24xx: fix Wunused-variable warning on !MMU ARM: samsung: fix PM debug build with DEBUG_LL but !MMU MAINTAINERS: mark linux-samsung-soc list non-moderated ARM: imx: Remove remnant board file support pieces ...

Pull more power management updates from Rafael Wysocki: "First of all, the adaptive voltage scaling (AVS) drivers go to new platform-specific locations as planned (this part was reported to have merge conflicts against the new arm-soc updates in linux-next). In addition to that, there are some fixes (intel_idle, intel_pstate, RAPL, acpi_cpufreq), the addition of on/off notifiers and idle state accounting support to the generic power domains (genpd) code and some janitorial changes all over. Specifics: - Move the AVS drivers to new platform-specific locations and get rid of the drivers/power/avs directory (Ulf Hansson). - Add on/off notifiers and idle state accounting support to the generic power domains (genpd) framework (Ulf Hansson, Lina Iyer). - Ulf will maintain the PM domain part of cpuidle-psci (Ulf Hansson). - Make intel_idle disregard ACPI _CST if it cannot use the data returned by that method (Mel Gorman). - Modify intel_pstate to avoid leaving useless sysfs directory structure behind if it cannot be registered (Chen Yu). - Fix domain detection in the RAPL power capping driver and prevent it from failing to enumerate the Psys RAPL domain (Zhang Rui). - Allow acpi-cpufreq to use ACPI _PSD information with Family 19 and later AMD chips (Wei Huang). - Update the driver assumptions comment in intel_idle and fix a kerneldoc comment in the runtime PM framework (Alexander Monakov, Bean Huo). - Avoid unnecessary resets of the cached frequency in the schedutil cpufreq governor to reduce overhead (Wei Wang). - Clean up the cpufreq core a bit (Viresh Kumar). - Make assorted minor janitorial changes (Daniel Lezcano, Geert Uytterhoeven, Hubert Jasudowicz, Tom Rix). - Clean up and optimize the cpupower utility somewhat (Colin Ian King, Martin Kaistra)" * tag 'pm-5.10-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (23 commits) PM: sleep: remove unreachable break PM: AVS: Drop the avs directory and the corresponding Kconfig PM: AVS: qcom-cpr: Move the driver to the qcom specific drivers PM: runtime: Fix typo in pm_runtime_set_active() helper comment PM: domains: Fix build error for genpd notifiers powercap: Fix typo in Kconfig "Plance" -> "Plane" cpufreq: schedutil: restore cached freq when next_f is not changed acpi-cpufreq: Honor _PSD table setting on new AMD CPUs PM: AVS: smartreflex Move driver to soc specific drivers PM: AVS: rockchip-io: Move the driver to the rockchip specific drivers PM: domains: enable domain idle state accounting PM: domains: Add curly braces to delimit comment + statement block PM: domains: Add support for PM domain on/off notifiers for genpd powercap/intel_rapl: enumerate Psys RAPL domain together with package RAPL domain powercap/intel_rapl: Fix domain detection intel_idle: Ignore _CST if control cannot be taken from the platform cpuidle: Remove pointless stub intel_idle: mention assumption that WBINVD is not needed MAINTAINERS: Add section for cpuidle-psci PM domain cpufreq: intel_pstate: Delete intel_pstate sysfs if failed to register the driver ...

PM: AVS: Drop the avs directory and the corresponding Kconfig

2020-10-22T16:39:32Z

All avs drivers have now been moved to their corresponding soc specific directories. Additionally, they don't depend on the POWER_AVS Kconfig anymore. Therefore, let's simply drop the drivers/power/avs directory altogether. Cc: Nishanth Menon Signed-off-by: Ulf Hansson Reviewed-by: Nishanth Menon Signed-off-by: Rafael J. Wysocki

PM: AVS: qcom-cpr: Move the driver to the qcom specific drivers

2020-10-22T16:38:21Z

The avs drivers are all SoC specific drivers that doesn't share any code. Instead they are located in a directory, mostly to keep similar functionality together. From a maintenance point of view, it makes better sense to collect SoC specific drivers like these, into the SoC specific directories. Therefore, let's move the qcom-cpr driver to the qcom directory.

power: reset: POWER_RESET_OCELOT_RESET should depend on Ocelot or Sparx5

2020-10-15T19:37:59Z

To add support for Sparx5, the dependency on MSCC_OCELOT was removed. However, this increases exposure of the driver question not only to Sparx5 platforms, but to everyone. Hence re-add the dependency on MSCC_OCELOT, and extend it with ARCH_SPARX5, to prevent asking the user about this driver when configuring a kernel without Ocelot and Sparx5 support.
