For the most part, this is now related to power management controllers, which have not yet been abstracted into a separate subsystem, and typically require some code in drivers/soc or arch/arm to control the power domains. Another large chunk here is a rework of the NVIDIA Tegra USB3.0 support, which was surprisingly tricky and took a long time to get done. Finally, reset controller handling as always gets merged through here as well" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (97 commits) arm-ccn: Enable building as module soc/tegra: pmc: Add generic PM domain support usb: xhci: tegra: Add Tegra210 support usb: xhci: Add NVIDIA Tegra XUSB controller driver dt-bindings: usb: xhci-tegra: Add Tegra210 XUSB controller support dt-bindings: usb: Add NVIDIA Tegra XUSB controller binding PCI: tegra: Support per-lane PHYs dt-bindings: pci: tegra: Update for per-lane PHYs phy: tegra: Add Tegra210 support phy: Add Tegra XUSB pad controller support dt-bindings: phy: tegra-xusb-padctl: Add Tegra210 support dt-bindings: phy: Add NVIDIA Tegra XUSB pad controller binding phy: core: Allow children node to be overridden clk: tegra: Add interface to enable hardware control of SATA/XUSB PLLs drivers: firmware: psci: make two helper functions inline soc: renesas: rcar-sysc: Add support for R-Car H3 power areas soc: renesas: rcar-sysc: Add support for R-Car E2 power areas soc: renesas: rcar-sysc: Add support for R-Car M2-N power areas soc: renesas: rcar-sysc: Add support for R-Car M2-W power areas soc: renesas: rcar-sysc: Add support for R-Car H2 power areas ...

* / ARM: EXYNOS: Properly skip unitialized parent clock in power domain onKrzysztof Kozlowski2016-04-251-1/+1
|/ | | | | | | | | | | | | | | | | We want to skip reparenting a clock on turning on power domain, if we do not have the parent yet. The parent is obtained when turning the domain off. However due to a typo, the loop is continued on IS_ERR() of clock being reparented, not on the IS_ERR() of the parent. Theoretically this could lead to OOPS on first turn on of a power domain, if there was no turn off before. Practically that should never happen because all power domains are turned on by default (reset value, bootloader does not turn off them usually) so the first action will be always turn off.

This driver is mainly used for setting misc bits of register from PMU IP of Exynos SoC which will be required to configure before Suspend/Resume. Currently all these settings are done in "arch/arm/mach-exynos/pmu.c" but moving ahead for ARM64 based SoC support, there is a need of this PMU driver in driver/* folder. This driver uses existing DT binding information and there should be no functionality change in the supported platforms.

| * | ARM: use "depends on" for SoC configs instead of "if" after promptMasahiro Yamada2015-12-011-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many ARM sub-architectures use prompts followed by "if" conditional, but it is wrong. Please notice the difference between config ARCH_FOO bool "Foo SoCs" if ARCH_MULTI_V7 and config ARCH_FOO bool "Foo SoCs" depends on ARCH_MULTI_V7 These two are *not* equivalent! In the former statement, it is not ARCH_FOO, but its prompt that depends on ARCH_MULTI_V7. So, it is completely valid that ARCH_FOO is selected by another, but ARCH_MULTI_V7 is still disabled. As it is not unmet dependency, Kconfig never warns. This is probably not what you want. The former should be used only when you need to do so, and you really understand what you are doing. (In most cases, it should be wrong!) For enabling/disabling sub-architectures, the latter is always correct. As a good side effect, this commit fixes some entries over 80 columns (mach-imx, mach-integrator, mach-mbevu).

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | The cpu booting of exynos5422 has been still broken since we discussed it in last year[1]. This patch is inspired from Odroid XU3 code (Actually, it was from samsung exynos vendor kernel)[2]. This weird reset code was founded exynos5420 octa cores series SoCs and only required for the first boot core is the Little core (Cortex A7). Some of the exynos5420 boards and all of the exynos5422 boards will require this code. There is two ways to check the little core is the first cpu. One is checking GPG2CON[1] GPIO value and the other is checking the cluster number of the first cpu. I selected the latter because it's more easier than the former.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new CPU clock type allows the use of generic CPUfreq driver. Switch Exynos4x12 to using generic cpufreq driver. Previously (when exynos-cpufreq driver was used with boost functionality) ARM_EXYNOS_CPU_FREQ_BOOST_SW config option (which enabled boost functionality) selected EXYNOS_THERMAL one. After switching Exynos4x12 platforms to use cpufreq-dt driver boost support is enabled in the cpufreq-dt driver itself (because there are turbo OPPs defined in the board's DTS file). However we still would like to allow enabling boost support only if thermal support is also enabled for Exynos platforms. To achieve this make ARCH_EXYNOS config option select THERMAL and EXYNOS_THERMAL ones. Please also note that the switch to use the generic cpufreq-dt driver fixes the minor issue present with the old code (support for 'boost' mode in the exynos-cpufreq driver was enabled for all supported SoCs even though 'boost' frequency was provided only for Exynos4x12 ones).

Most of this is removal of legacy (non-DT) support of shmobile platforms. There is also removal of two non-DT platforms on OMAP, and the plat-samsung directory is cleaned out by moving most of the previously shared-location-but-not-actually-shared files from there to the appropriate mach directories instead. There are other sets of changes in here as well: - Rob Herring removed use of set_irq_flags under all platforms and moved to genirq alternatives - a series of timer API conversions to set-state interface - ep93xx, nomadik and ux500 cleanups from Linus Walleij - __init annotation fixes from Nicolas Pitre + a bunch of other changes that all add up to a nice set of cleanups" * tag 'armsoc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (108 commits) ARM/fb: ep93xx: switch framebuffer to use modedb only ARM: gemini: Setup timer3 as free running timer ARM: gemini: Use timer1 for clockevent ARM: gemini: Add missing register definitions for gemini timer ARM: ep93xx/timer: Migrate to new 'set-state' interface ARM: nomadik: push accelerometer down to boards ARM: nomadik: move l2x0 setup to device tree ARM: nomadik: selectively enable UART0 on boards ARM: nomadik: move hog code to use DT hogs ARM: shmobile: Fix mismerges ARM: ux500: simplify secondary CPU boot ARM: SAMSUNG: remove keypad-core header in plat-samsung ARM: SAMSUNG: local watchdog-reset header in mach-s3c64xx ARM: SAMSUNG: local onenand-core header in mach-s3c64xx ARM: SAMSUNG: local irq-uart header in mach-s3c64xx ARM: SAMSUNG: local backlight header in mach-s3c64xx ARM: SAMSUNG: local ata-core header in mach-s3c64xx ARM: SAMSUNG: local regs-usb-hsotg-phy header in mach-s3c64xx ARM: SAMSUNG: local spi-core header in mach-s3c24xx ARM: SAMSUNG: local nand-core header in mach-s3c24xx ...
