Pull ARM SoC multiplatform code updates from Arnd Bergmann: "This branch is the culmination of 5 years of effort to bring the ARMv6 and ARMv7 platforms together such that they can all be enabled and boot the same kernel. It has been a tremendous amount of cleanup and refactoring by a huge number of people, and creation of several new (and major) subsystems to better abstract out all the platform details in an appropriate manner. The bulk of this branch is a large patchset from Arnd that brings several of the more minor and older platforms we have closer to multiplatform support. Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview Much of this is moving around header files from old mach directories, but there are also some cleanup patches of debug_ll (lowlevel debug per-platform options) and other parts. Linus Walleij also has some patchs to clean up the older ARM Realview platforms by finally introducing DT support, and Rob Herring has some for ARM Versatile which is now DT-only. Both of these platforms are now multiplatform. Finally, a couple of patches from Russell for Dove PMU, and a fix from Valentin Rothberg for Exynos ADC, which were rebased on top of the series to avoid conflicts" * tag 'armsoc-multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (75 commits) ARM: realview: don't select SMP_ON_UP for UP builds ARM: s3c: simplify s3c_irqwake_{e,}intallow definition ARM: s3c64xx: fix pm-debug compilation iio: exynos-adc: fix irqf_oneshot.cocci warnings ARM: realview: build realview-dt SMP support only when used ARM: realview: select apropriate targets ARM: realview: clean up header files ARM: realview: make all header files local ARM: no longer make CPU targets visible separately ARM: integrator: use explicit core module options ARM: realview: enable multiplatform ARM: make default platform work for NOMMU ARM: debug-ll: move DEBUG_LL_UART_EFM32 to correct Kconfig location ARM: defconfig: use correct debug_ll settings ARM: versatile: convert to multi-platform ARM: versatile: merge mach code into a single file ARM: versatile: switch to DT only booting and remove legacy code ARM: versatile: add DT based PCI detection ARM: pxa: mark ezx structures as __maybe_unused ARM: pxa: mark raumfeld init functions as __maybe_unused ...

ARM: bcm2835: add rpi power domain driver

2015-12-22T04:00:41Z

This patch adds support for several power domains on Raspberry Pi, including USB (so it can be enabled even if the bootloader didn't do it), and graphics. This patch is the combined work of Eric Anholt (who wrote USB support inside of the Raspberry Pi firmware driver, and wrote the non-USB domain support) and Alexander Aring (who separated the original USB work out from the firmware driver).

Pull ARM SoC driver updates from Olof Johansson: "As we've enabled multiplatform kernels on ARM, and greatly done away with the contents under arch/arm/mach-*, there's still need for SoC-related drivers to go somewhere. Many of them go in through other driver trees, but we still have drivers/soc to hold some of the "doesn't fit anywhere" lowlevel code that might be shared between ARM and ARM64 (or just in general makes sense to not have under the architecture directory). This branch contains mostly such code: - Drivers for qualcomm SoCs for SMEM, SMD and SMD-RPM, used to communicate with power management blocks on these SoCs for use by clock, regulator and bus frequency drivers. - Allwinner Reduced Serial Bus driver, again used to communicate with PMICs. - Drivers for ARM's SCPI (System Control Processor). Not to be confused with PSCI (Power State Coordination Interface). SCPI is used to communicate with the assistant embedded cores doing power management, and we have yet to see how many of them will implement this for their hardware vs abstracting in other ways (or not at all like in the past). - To make confusion between SCPI and PSCI more likely, this release also includes an update of PSCI to interface version 1.0. - Rockchip support for power domains. - A driver to talk to the firmware on Raspberry Pi" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (57 commits) soc: qcom: smd-rpm: Correct size of outgoing message bus: sunxi-rsb: Add driver for Allwinner Reduced Serial Bus bus: sunxi-rsb: Add Allwinner Reduced Serial Bus (RSB) controller bindings ARM: bcm2835: add mutual inclusion protection drivers: psci: make PSCI 1.0 functions initialization version dependent dt-bindings: Correct paths in Rockchip power domains binding document soc: rockchip: power-domain: don't try to print the clock name in error case soc: qcom/smem: add HWSPINLOCK dependency clk: berlin: add cpuclk ARM: berlin: dts: add CLKID_CPU for BG2Q ARM: bcm2835: Add the Raspberry Pi firmware driver soc: qcom: smem: Move RPM message ram out of smem DT node soc: qcom: smd-rpm: Correct the active vs sleep state flagging soc: qcom: smd: delete unneeded of_node_put firmware: qcom-scm: build for correct architecture level soc: qcom: smd: Correct SMEM items for upper channels qcom-scm: add missing prototype for qcom_scm_is_available() qcom-scm: fix endianess issue in __qcom_scm_is_call_available soc: qcom: smd: Reject send of too big packets soc: qcom: smd: Handle big endian CPUs ...

soc: rockchip: power-domain: Add power domain driver

2015-10-06T07:53:28Z

This driver is found on RK3288 SoCs. In order to meet high performance and low power requirements, a power management unit is designed or saving power when RK3288 in low power mode. The RK3288 PMU is dedicated for managing the power of the whole chip. PMU can work in the Low Power Mode by setting bit[0] of PMU_PWRMODE_CON register. After setting the register, PMU would enter the Low Power mode. In the low power mode, pmu will auto power on/off the specified power domain, send idle req to specified power domain, shut down/up pll and so on. All of above are configurable by setting corresponding registers.

ARM: dove: create a proper PMU driver for power domains, PMU IRQs and resets

2015-08-05T16:36:49Z

The PMU device contains an interrupt controller, power control and resets. The interrupt controller is a little sub-standard in that there is no race free way to clear down pending interrupts, so we try to avoid problems by reducing the window as much as possible, and clearing as infrequently as possible. The interrupt support is implemented using an IRQ domain, and the parent interrupt referenced in the standard DT way. The power domains and reset support is closely related - there is a defined sequence for powering down a domain which is tightly coupled with asserting the reset. Hence, it makes sense to group these two together, and in order to avoid any locking contention disrupting this sequence, we avoid the use of syscon or regmap. This patch adds the core PMU driver: power domains must be defined in the DT file in order to make use of them. The reset controller can be referenced in the standard way for reset controllers.

drivers: soc: sunxi: Introduce SoC driver to map SRAMs

2015-06-01T15:57:34Z

The Allwinner SoCs have a handful of SRAM that can be either mapped to be accessible by devices or the CPU. That mapping is controlled by an SRAM controller, and that mapping might not be set by the bootloader, for example if the device wasn't used at all, or if we're using solutions like the U-Boot's Falcon Boot. We could also imagine changing this at runtime for example to change the mapping of these SRAMs to use them for suspend/resume or runtime memory rate change, if that ever happens. These use cases require some API in the kernel to control that mapping, exported through a drivers/soc driver. This driver also implement a debugfs file that shows the SRAM found in the system, the current mapping and the SRAM that have been claimed by some drivers in the kernel.
