The Stout newly has two DA9210 regulators, so the quirk is extended to handle another DA9210 at i2c address 0x70." - Add watchdog support This is the SoC portion of the following solution. It is not yet enabled in DT as it is not functional without clock dependencies in place. Fabrizio Castro says "this series has been around for some time as RFC, and it has collected useful comments from the community along the way. The solution proposed by this patch set works for most R-Car Gen2 and RZ/G1 devices, but not all of them. We now know that for some R-Car Gen2 early revisions there is no proper software fix. Anyway, no product has been built around early revisions, but development boards mounting early revisions (basically prototypes) are still out there. As a result, this series isn't enabling the internal watchdog on R-Car Gen2 boards, developers may enable it in board specific device trees if needed. This series has been tested by me on the iwg20d, iwg22d, Lager, Alt, and Koelsch boards. The problem =========== To deal with SMP on R-Car Gen2 and RZ/G1, we install a reset vector to ICRAM1 and we program the [S]BAR registers so that when we turn ON the non-boot CPUs they are redirected to the reset vector installed by Linux in ICRAM1, and eventually they continue the execution to RAM, where the SMP bring-up code will take care of the rest. The content of the [S]BAR registers survives a watchdog triggered reset, and as such after the watchdog fires the boot core will try and execute the SMP bring-up code instead of jumping to the bootrom code. The fix ======= The main strategy for the solution is to let the reset vector decide if it needs to jump to shmobile_boot_fn or to the bootrom code. In a watchdog triggered reset scenario, since the [S]BAR registers keep their values, the boot CPU will jump into the newly designed reset vector, the assembly routine will eventually test WOVF (a bit in register RWTCSRA that indicates if the watchdog counter has overflown, the value of this bit gets retained in this scenario), and jump to the bootrom code which will in turn load up the bootloader, etc. When bringing up SMP or using CPU hotplug, the reset vector will jump to shmobile_boot_fn instead." * R-Car Rst - Add support for R-Car V3H (r8a77980) and V3H (r8a77980) * R-Car SYSC - Mark rcar_sysc_matches[] __initconst Geert Uytterhoeven says "This frees another 1764 bytes (arm32/shmobile_defconfig) or 1000 bytes (arm64/renesas_defconfig) of memory after kernel init." - Fix power area parents Sergei Shtylyov says "According to the figure 9.2(b) of the R-Car Series, 3rd Generation User’s Manual: Hardware Rev. 0.80 the A2IRn and A2SCn power areas in R8A77970 have the A3IR area as a parent, thus the SYSC driver has those parents wrong.." - Add support for R-Car V3H (r8a77980) and V3H (r8a77980) * tag 'renesas-soc-for-v4.17' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/horms/renesas: ARM: shmobile: rcar-gen2: Add watchdog support ARM: shmobile: Add watchdog support ARM: shmobile: rcar-gen2: Fix error check in regulator quirk soc: renesas: rcar-rst: Add support for R-Car M3-N ARM: shmobile: stout: enable R-Car Gen2 regulator quirk soc: renesas: rcar-sysc: Add R-Car M3-N support soc: renesas: Identify R-Car M3-N soc: renesas: rcar-sysc: add R8A77980 support dt-bindings: power: add R8A77980 SYSC power domain definitions soc: renesas: r8a77970-sysc: fix power area parents soc: renesas: rcar-rst: Enable watchdog as reset trigger for Gen2 soc: renesas: rcar-rst: add R8A77980 support soc: renesas: identify R-Car V3H soc: renesas: rcar-sysc: Mark rcar_sysc_matches[] __initconst

Merge tag 'omap-for-v4.17/defconfig-signed' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc Pull "Defconfig updates for omap variants for v4.17 merge window" from Tony Lindgren: We need to enable MMC_SDHCI option in both omap2plus_defconfig and multi_v7_defconfig so systems are able to mount root when the dts files get updated for sdhci. Then let's update omap2plus_defconfig so we can patch it easier. And as Arnd noticed earlier, just running make savedefconfig will accidentally drop few Kconfig options. This is happening because some options are no longer available as loadable modules like LIRC. Or new dependencies have been added such as SND_OSSEMUL for selecting SOUND_OSS_CORE. So we first move the unchanged options around to their make savedefconfig suggested place, then update the options to prevent make savedefconfig dropping some options accidentally, and then finally drop the unused options. And after that we enable options DRM_OMAP and 8250_OMAP. These both have been around for years now. And we do have 8250_OMAP warn about console being redirected with SERIAL_8250_OMAP_TTYO_FIXUP option that is enabled by default. Some users may need to update their inittab to use ttyS* instead of ttyO* though. If this turns out to be a problem, we may want to introduce a separate compatible for 8250-omap. But I think we're good to go with the SERIAL_8250_OMAP_TTYO_FIXUP warning now. Let's not update multi_v7_defconfig yet though and first see how 8250_OMAP change plays out. We also enable few new options for PM on am335x and am437x, and CEC in omap2plus_defconfig. Naturally similar options can be later on added to multi_v7_defconfig, but in this series we only enable OTG, MUSB and the related PHYs in multi_v7_defconfig to make it more usable for distros. * tag 'omap-for-v4.17/defconfig-signed' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: multi_v7_defconfig: Enable USB gadget configfs as loadable module ARM: multi_v7_defconfig: Enable various USB PHYs found on omap variants ARM: multi_v7_defconfig: Enable OTG and MUSB as loadable modules ARM: omap2plus_defconfig: Enable 8250_OMAP ARM: omap2plus_defconfig: Switch to use omapdrm by default ARM: omap2plus_defconfig: Enable CEC ARM: omap2plus_defconfig: Enable am335x and am437x PM options ARM: omap2plus_defconfig: Drop unneeded options ARM: omap2plus_defconfig: Add SND_OSSEMUL ARM: omap2plus_defconfig: Update LIRC options ARM: omap2plus_defconfig: Select MFD_TI_LMU ARM: omap2plus_defconfig: Add SERIAL_DEV for bluetooth ARM: omap2plus_defconfig: Update for moved options ARM: omap2plus_defconfig: Enable CONFIG_MMC_SDHCI_OMAP ARM: multi_v7_defconfig: Enable CONFIG_MMC_SDHCI_OMAP Signed-off-by: Arnd Bergmann <arnd@arndb.de>

Since commit 04c8b0f8 ("irqchip/gic: Make locking a BL_SWITCHER only feature") coupled CPU idle freezes from time to time on Exynos4210. Later commit 313c8c16 ("PM / CPU: replace raw_notifier with atomic_notifier") changed the context in which the CPU idle code is executed, what results in fully reproducible freeze all the time. However, almost the same coupled CPU idle code works fine on Exynos3250 regardless of the changes made in the mentioned commits. It turned out that the IPI call used on Exynos4210 is conflicting with the change done in the first mentioned commit in GIC. Fix this by using the same code path as for Exynos3250, instead of the IPI call for synchronization with second CPU core, call dsb_sev() directly. Tested on Exynos4210-based Trats and Origen boards.
