* ARM: shmobile: R-Mobile: Move pm-rmobile to drivers/soc/renesas/Geert Uytterhoeven2018-11-301-352/+0
| | | | | | | | | | | | | | The pm-rmobile driver is really a driver for the System Controller (SYSC) found in R-Mobile SoCs. An equivalent driver for R-Car SoCs is already located under drivers/soc/renesas/. Hence move the pm-rmobile driver from arch/arm/mach-shmobile/ to drivers/soc/renesas/, and rename it to rmobile-sysc. Enable compile-testing on non-ARM and non-R-Mobile SoCs.

* ARM: shmobile: R-Mobile: Clean up struct rmobile_pm_domainGeert Uytterhoeven2018-11-301-19/+18
| | | | | | | | | | | | | | | | Commit 59b89af1d5551c12 ("ARM: shmobile: sh7372: Remove Legacy C SoC code") removed the last user of the rmobile_pm_domain.resume() callback. Commit 44d88c754e57a6d9 ("ARM: shmobile: Remove legacy SoC code for R-Mobile A1") removed the last user of the rmobile_pm_domain.no_debug flag and of the "pm-rmobile.h" header file (outside the actual driver). Hence remove no longer used rmobile_pm_domain members, and absorb the header file into the driver.

Thanks everyone for working on this, and welcome to the new maintainers! The "virt" platform on qemy or kvm can now be used in big-endian mode without additional tricks, thanks to Jason Donenfeld. Once again, we gain support for another NXP i.MX6 variant, this time it's the i.MX 6ULZ 32-bit single-core version. On arm64, we add support for two SoCs from Renesas: RZ/G2E (r8a774c0) and RZ/G2M (r8a774a1). These are described as microcontrollers on the manufacturer website, but appear to be rather powerful.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The R-Mobile PM Domain driver manages both power domains and a clock domain. The clock domain part is very similar to the CPG/MSTP Clock Domain, which is used on shmobile SoCs without device power domains, except for the way how clocks suitable for power management are selected: - The former uses the first clock tied to the device through the NULL con_id, which is a relic from the legacy pm_clk_notifier-based method in drivers/sh/pm_runtime.c, - The latter looks for suitable clocks in DT, which is more future-proof. All platforms using this driver are now supported in DT-based ARM multi-platform builds only, hence switch to using the CPG/MSTP Clock Domain helpers.

On sh73a0 PM domains A4BC0 and A4BC1 each contain an SDRAM Bus State Controller (SBSC). On r8a73a4 PM domain A3BC contains two DDR Bus Controllers (DBSC). In both cases, there are no other devices in these PM domains, so they were eligible for power down, crashing the system. On r8a7740 the DDR3 Bus State Controller (DBSC3) is located in A4S, whose child domain A3SM contains the CPU core. Hence A4S is never turned off, and no crash happened.

| | | | | | | | | | | | | | | | | | | | | | | | Populate the PM domains from DT, and provide support to hook up devices to their respective PM domain. The always-on power area (e.g. C5 on r8a7740) is created as a PM domain without software control, to allow Run-Time management of module clocks for hardware blocks inside this area. Special cases like PM domains containing CPUs, the console device, or Coresight-ETM, are handled by scanning the DT topology. As long as the ARM debug/perf code doesn't use resource management with runtime PM support, the power area containing Coresight-ETM (e.g. D4 on r8a7740) must be kept powered to avoid a crash during resume from s2ram (dbg_cpu_pm_notify() calls reset_ctrl_regs() unconditionally, causing an undefined instruction oops). Initialization is done from core_initcall(), as the "renesas,intc-irqpin" driver uses postcore_initcall().

Many thanks to Thomas Gleixner for his help with this work. Second is an update of the generic PM domains code that has been in need of some care for quite a while. Unused code is being removed, DT support is being added and domains are now going to be attached to devices in bus type code in analogy with the ACPI PM domain. The majority of work here was done by Ulf Hansson who also has been the most active developer this time. Apart from this we have a traditional ACPICA update, this time to upstream version 20140828 and a few ACPI wakeup interrupts handling patches on top of the general rework mentioned above. There also are several cpufreq commits including renaming the cpufreq-cpu0 driver to cpufreq-dt, as this is what implements generic DT-based cpufreq support, and a new DT-based idle states infrastructure for cpuidle. In addition to that, the ACPI LPSS driver is updated, ACPI support for Apple machines is improved, a few bugs are fixed and a few cleanups are made all over. Finally, the Adaptive Voltage Scaling (AVS) subsystem now has a tree maintained by Kevin Hilman that will be merged through the PM tree. Numbers-wise, the generic PM domains update takes the lead this time with 32 non-merge commits, second is cpufreq (15 commits) and the 3rd place goes to the wakeup interrupts handling rework (13 commits). Specifics: - Rework the handling of wakeup IRQs by the IRQ core such that all of them will be switched over to "wakeup" mode in suspend_device_irqs() and in that mode the first interrupt will abort system suspend in progress or wake up the system if already in suspend-to-idle (or equivalent) without executing any interrupt handlers. Among other things that eliminates the wakeup-related motivation to use the IRQF_NO_SUSPEND interrupt flag with interrupts which don't really need it and should not use it (Thomas Gleixner and Rafael Wysocki) - Switch over ACPI to handling wakeup interrupts with the help of the new mechanism introduced by the above IRQ core rework (Rafael Wysocki) - Rework the core generic PM domains code to eliminate code that's not used, add DT support and add a generic mechanism by which devices can be added to PM domains automatically during enumeration (Ulf Hansson, Geert Uytterhoeven and Tomasz Figa). - Add debugfs-based mechanics for debugging generic PM domains (Maciej Matraszek). - ACPICA update to upstream version 20140828. Included are updates related to the SRAT and GTDT tables and the _PSx methods are in the METHOD_NAME list now (Bob Moore and Hanjun Guo). - Add _OSI("Darwin") support to the ACPI core (unfortunately, that can't really be done in a straightforward way) to prevent Thunderbolt from being turned off on Apple systems after boot (or after resume from system suspend) and rework the ACPI Smart Battery Subsystem (SBS) driver to work correctly with Apple platforms (Matthew Garrett and Andreas Noever). - ACPI LPSS (Low-Power Subsystem) driver update cleaning up the code, adding support for 133MHz I2C source clock on Intel Baytrail to it and making it avoid using UART RTS override with Auto Flow Control (Heikki Krogerus). - ACPI backlight updates removing the video_set_use_native_backlight quirk which is not necessary any more, making the code check the list of output devices returned by the _DOD method to avoid creating acpi_video interfaces that won't work and adding a quirk for Lenovo Ideapad Z570 (Hans de Goede, Aaron Lu and Stepan Bujnak) - New Win8 ACPI OSI quirks for some Dell laptops (Edward Lin) - Assorted ACPI code cleanups (Fabian Frederick, Rasmus Villemoes, Sudip Mukherjee, Yijing Wang, and Zhang Rui) - cpufreq core updates and cleanups (Viresh Kumar, Preeti U Murthy, Rasmus Villemoes) - cpufreq driver updates: cpufreq-cpu0/cpufreq-dt (driver name change among other things), ppc-corenet, powernv (Viresh Kumar, Preeti U Murthy, Shilpasri G Bhat, Lucas Stach) - cpuidle support for DT-based idle states infrastructure, new ARM64 cpuidle driver, cpuidle core cleanups (Lorenzo Pieralisi, Rasmus Villemoes) - ARM big.LITTLE cpuidle driver updates: support for DT-based initialization and Exynos5800 compatible string (Lorenzo Pieralisi, Kevin Hilman) - Rework of the test_suspend kernel command line argument and a new trace event for console resume (Srinivas Pandruvada, Todd E Brandt) - Second attempt to optimize swsusp_free() (hibernation core) to make it avoid going through all PFNs which may be way too slow on some systems (Joerg Roedel) - devfreq updates (Paul Bolle, Punit Agrawal, Ãrjan Eide). - rockchip-io Adaptive Voltage Scaling (AVS) driver and AVS entry update in MAINTAINERS (Heiko Stübner, Kevin Hilman) - PM core fix related to clock management (Geert Uytterhoeven) - PM core's sysfs code cleanup (Johannes Berg)" * tag 'pm+acpi-3.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (105 commits) ACPI / fan: printk replacement PM / clk: Fix crash in clocks management code if !CONFIG_PM_RUNTIME PM / Domains: Rename cpu_data to cpuidle_data cpufreq: cpufreq-dt: fix potential double put of cpu OF node cpufreq: cpu0: rename driver and internals to 'cpufreq_dt' PM / hibernate: Iterate over set bits instead of PFNs in swsusp_free() cpufreq: ppc-corenet: remove duplicate update of cpu_data ACPI / sleep: Rework the handling of ACPI GPE wakeup from suspend-to-idle PM / sleep: Rename platform suspend/resume functions in suspend.c PM / sleep: Export dpm_suspend_late/noirq() and dpm_resume_early/noirq() ACPICA: Introduce acpi_enable_all_wakeup_gpes() ACPICA: Clear all non-wakeup GPEs in acpi_hw_enable_wakeup_gpe_block() ACPI / video: check _DOD list when creating backlight devices PM / Domains: Move dev_pm_domain_attach|detach() to pm_domain.h cpufreq: Replace strnicmp with strncasecmp cpufreq: powernv: Set the cpus to nominal frequency during reboot/kexec cpufreq: powernv: Set the pstate of the last hotplugged out cpu in policy->cpus to minimum cpufreq: Allow stop CPU callback to be used by all cpufreq drivers PM / devfreq: exynos: Enable building exynos PPMU as module PM / devfreq: Export helper functions for drivers ...

| * ARM: shmobile: Rework adding devices to PM domains on MackerelRafael J. Wysocki2012-09-041-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | On SH7372 and Mackerel devices are added to PM domains through a series of rmobile_add_device_to_domain_td() calls where the last argument is always the same. This is quite inefficient, so add a common function for adding devices to PM domains that reads the domain-device pairs information from a table and use it during SH7372 and Mackerel initialization.

| * ARM: shmobile: Allow device latencies to be specified directlyRafael J. Wysocki2012-09-041-3/+4
| | | | | | | | | | | | | | | | | | | | | | Make it possible to specify device start/stop and save/restore state latencies directy when adding devices to PM domains. For this purpose, introduce rmobile_add_device_to_domain_td() whose third argument is a pointer to a struct gpd_timing_data object containing device latency data. Signed-off-by: Rafael J.

| | | | | | | | | | | | | | | | | | | | Since rmobile_init_pm_domain() is not called anywhere outside of arch/arm/mach-shmobile/pm-rmobile.c any more, it can be made static and its header may be removed from pm-rmobile.h.

| | | | | | | | | | | | | | | | | | | | | | | | Make the power management code under arch/arm/mach-shmobile/ use pm_genpd_add_subdomain_names() for adding subdomains to power domains, which makes it possible to drop rmobile_pm_add_subdomain() and will allow us to carry out those operations for domain objects stored in tables in a straightforward way.

* | ARM: shmobile: use __iomem pointers for MMIOArnd Bergmann2012-09-181-3/+3
|/ | | | | | | | | | | | | | | | ARM is moving to stricter checks on readl/write functions, so we need to use the correct types everywhere. This patch is a bit ugly for shmobile, which is the only platform that just uses integer literals all over the place, but I can't see a better way to do this.
