There are additions to the clock core code for some of the basic types (e.g. the common divider type has some fixes and featured added to it). One minor annoyance is a last-minute dependency that wasn't handled quite right.

| * clk: berlin: add driver for BG2x audio/video PLLSebastian Hesselbarth2014-05-29
| | | | | | | | | | | | | | | | | | | | | | | | This is a driver for the AVPLLs built upon a VCO with 8 channels each found on Marvell Berlin2 SoCs. While both VCOs found on BG2/BG2CD share the same register set, sometimes registers shifts for one of the VCOs are a bit off. Nothing serious that should require a separate driver, so deal with both VCOs in a single driver instead.

We have no major new features this time, but there are a few significant changes of how things work. The most visible one will probably be that we are now going to create platform devices rather than PNP devices by default for ACPI device objects with _HID. That was long overdue and will be really necessary to be able to use the same drivers for the same hardware blocks on ACPI and DT-based systems going forward. We're not expecting fallout from this one (as usual), but it's something to watch nevertheless. The second change having a chance to be visible is that ACPI video will now default to using native backlight rather than the ACPI backlight interface which should generally help systems with broken Win8 BIOSes. We're hoping that all problems with the native backlight handling that we had previously have been addressed and we are in a good enough shape to flip the default, but this change should be easy enough to revert if need be. In addition to that, the system suspend core has a new mechanism to allow runtime-suspended devices to stay suspended throughout system suspend/resume transitions if some extra conditions are met (generally, they are related to coordination within device hierarchy). However, enabling this feature requires cooperation from the bus type layer and for now it has only been implemented for the ACPI PM domain (used by ACPI-enumerated platform devices mostly today). Also, the acpidump utility that was previously shipped as a separate tool will now be provided by the upstream ACPICA along with the rest of ACPICA code, which will allow it to be more up to date and better supported, and we have one new cpuidle driver (ARM clps711x). The rest is improvements related to certain specific use cases, cleanups and fixes all over the place. Specifics: - ACPICA update to upstream version 20140424. That includes a number of fixes and improvements related to things like GPE handling, table loading, headers, memory mapping and unmapping, DSDT/SSDT overriding, and the Unload() operator. The acpidump utility from upstream ACPICA is included too. From Bob Moore, Lv Zheng, David Box, David Binderman, and Colin Ian King. - Fixes and cleanups related to ACPI video and backlight interfaces from Hans de Goede. That includes blacklist entries for some new machines and using native backlight by default. - ACPI device enumeration changes to create platform devices rather than PNP devices for ACPI device objects with _HID by default. PNP devices will still be created for the ACPI device object with device IDs corresponding to real PNP devices, so that change should not break things left and right, and we're expecting to see more and more ACPI-enumerated platform devices in the future. From Zhang Rui and Rafael J Wysocki. - Updates for the ACPI LPSS (Low-Power Subsystem) driver allowing it to handle system suspend/resume on Asus T100 correctly. From Heikki Krogerus and Rafael J Wysocki. - PM core update introducing a mechanism to allow runtime-suspended devices to stay suspended over system suspend/resume transitions if certain additional conditions related to coordination within device hierarchy are met. Related PM documentation update and ACPI PM domain support for the new feature. From Rafael J Wysocki. - Fixes and improvements related to the "freeze" sleep state.

From Rafael J Wysocki and Zhang Rui. - Miscellaneous fixes and updates of the ACPI core from Aaron Lu, Bjørn Mork, Hanjun Guo, Lan Tianyu, and Rafael J Wysocki. - Fixes and cleanups for the ACPI processor and ACPI PAD (Processor Aggregator Device) drivers from Baoquan He, Manuel Schölling, Tony Camuso, and Toshi Kani. - System suspend/resume optimization in the ACPI battery driver from Lan Tianyu. - OPP (Operating Performance Points) subsystem updates from Chander Kashyap, Mark Brown, and Nishanth Menon. - cpufreq core fixes, updates and cleanups from Srivatsa S Bhat, Stratos Karafotis, and Viresh Kumar. - Updates, fixes and cleanups for the Tegra, powernow-k8, imx6q, s5pv210, nforce2, and powernv cpufreq drivers from Brian Norris, Jingoo Han, Paul Bolle, Philipp Zabel, Stratos Karafotis, and Viresh Kumar. - intel_pstate driver fixes and cleanups from Dirk Brandewie, Doug Smythies, and Stratos Karafotis. - Enabling the big.LITTLE cpufreq driver on arm64 from Mark Brown. - Fix for the cpuidle menu governor from Chander Kashyap. - New ARM clps711x cpuidle driver from Alexander Shiyan. - Hibernate core fixes and cleanups from Chen Gang, Dan Carpenter, Fabian Frederick, Pali Rohár, and Sebastian Capella. - Intel RAPL (Running Average Power Limit) driver updates from Jacob Pan. - PNP subsystem updates from Bjorn Helgaas and Fabian Frederick. - devfreq core updates from Chanwoo Choi and Paul Bolle. - devfreq updates for exynos4 and exynos5 from Chanwoo Choi and Bartlomiej Zolnierkiewicz. - turbostat tool fix from Jean Delvare. - cpupower tool updates from Prarit Bhargava, Ramkumar Ramachandra and Thomas Renninger. - New ACPI ec_access.c tool for poking at the EC in a safe way from Thomas Renninger" * tag 'pm+acpi-3.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (187 commits) ACPICA: Namespace: Remove _PRP method support. intel_pstate: Improve initial busy calculation intel_pstate: add sample time scaling intel_pstate: Correct rounding in busy calculation intel_pstate: Remove C0 tracking PM / hibernate: fixed typo in comment ACPI: Fix x86 regression related to early mapping size limitation ACPICA: Tables: Add mechanism to control early table checksum verification.

Machines in this family use peripheral clocks implemented by "Kona" clock control units (CCUs). (Other Broadcom SoC families use Kona style CCUs as well, but support for them is not yet upstream.) A BCM281xx SoC has multiple CCUs, each of which manages a set of clocks on the SoC. A Kona peripheral clock is composite clock that may include a gate, a parent clock multiplexor, and zero, one or two dividers. There is a variety of gate types, and many gates implement hardware-managed gating (often called "auto-gating"). Most dividers divide their input clock signal by an integer value (one or more). There are also "fractional" dividers which allow division by non-integer values. To accomodate such dividers, clock rates and dividers are generally maintained by the code in "scaled" form, which allows integer and fractional dividers to be handled in a uniform way. If present, the gate for a Kona peripheral clock must be enabled when a change is made to its multiplexor or one of its dividers. Additionally, dividers and multiplexors have trigger registers which must be used whenever the divider value or selected parent clock is changed. The same trigger is often used for a divider and multiplexor, and a BCM281xx peripheral clock occasionally has two triggers. The gate, dividers, and parent clock selector are treated in this code as "components" of a peripheral clock. Their functionality is implemented directly--e.g. the common clock framework gate implementation is not used for a Kona peripheral clock gate. (This has being considered though, and the intention is to evolve this code to leverage common code as much as possible.) The source code is divided into three general portions: drivers/clk/bcm/clk-kona.h drivers/clk/bcm/clk-kona.c These implement the basic Kona clock functionality, including the clk_ops methods and various routines to manipulate registers and interpret their values. This includes some functions used to set clocks to a desired initial state (though this feature is only partially implemented here). drivers/clk/bcm/clk-kona-setup.c This contains generic run-time initialization code for data structures representing Kona CCUs and clocks. This encapsulates the clock structure initialization that can't be done statically. Note that there is a great deal of validity-checking code here, making explicit certain assumptions in the code. This is mostly useful for adding new clock definitions and could possibly be disabled for production use. drivers/clk/bcm/clk-bcm281xx.c This file defines the specific CCUs used by BCM281XX family SoCs, as well as the specific clocks implemented by each. It declares a device tree clock match entry for each CCU defined. include/dt-bindings/clock/bcm281xx.h This file defines the selector (index) values used to identify a particular clock provided by a CCU. It consists entirely of C preprocessor constants, to be used by both the C source and device tree source files.

* / clk: at91: add PMC base supportBoris BREZILLON2013-12-02
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds at91 PMC (Power Management Controller) base support. All at91 clocks managed by the PMC unit will use this framework. This framework provides the following fonctionalities: - define a new struct at91_pmc to hide PMC internals (lock, PMC memory mapping, irq domain, ...) - read/write helper functions (pmc_read/write) to access PMC registers - lock/unlock helper functions (pmc_lock/unlock) to lock/unlock access to pmc registers - a new irq domain and its associated irq chip to request PMC specific interrupts (useful for clk prepare callbacks) The PMC unit is declared as a dt clk provider (CLK_OF_DECLARE), and every clk using this framework will declare a table of of_at91_clk_init_cb_t and add it to the pmc_clk_ids table. When the pmc dt clock setup function is called (by of_clk_init function), it triggers the registration of every supported child clk (those matching the definitions in pmc_clk_ids). This patch copies at91_pmc_base (memory mapping) and at91sam9_idle (function) from arch/arm/mach-at91/clock.c (which is not compiled if COMMON_CLK_AT91 is enabled).

Like last time, Renesas sh-mobile is now the platform with the most changes, followed by OMAP and EXYNOS. Two new platforms, TI Keystone and Rockchips RK3xxx are added in this branch, both containing almost no platform specific code at all, since they are using generic subsystem interfaces for clocks, pinctrl, interrupts etc. The device drivers are getting merged through the respective subsystem maintainer trees. One more SoC (u300) is now multiplatform capable and several others (shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving towards that goal with this series but need more work. Also noteworthy is the work on PCI here, which is traditionally part of the SoC specific code. With the changes done by Thomas Petazzoni, we can now more easily have PCI host controller drivers as loadable modules and keep them separate from the platform code in drivers/pci/host. This has already led to the discovery that three platforms (exynos, spear and imx) are actually using an identical PCIe host controller and will be able to share a driver once support for spear and imx is added." * tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (480 commits) ARM: integrator: let pciv3 use mem/premem from device tree ARM: integrator: set local side PCI addresses right ARM: dts: Add pcie controller node for exynos5440-ssdk5440 ARM: dts: Add pcie controller node for Samsung EXYNOS5440 SoC ARM: EXYNOS: Enable PCIe support for Exynos5440 pci: Add PCIe driver for Samsung Exynos ARM: OMAP5: voltagedomain data: remove temporary OMAP4 voltage data ARM: keystone: Move CPU bringup code to dedicated asm file ARM: multiplatform: always pick one CPU type ARM: imx: select syscon for IMX6SL ARM: keystone: select ARM_ERRATA_798181 only for SMP ARM: imx: Synertronixx scb9328 needs to select SOC_IMX1 ARM: OMAP2+: AM43x: resolve SMP related build error dmaengine: edma: enable build for AM33XX ARM: edma: Add EDMA crossbar event mux support ARM: edma: Add DT and runtime PM support to the private EDMA API dmaengine: edma: Add TI EDMA device tree binding arm: add basic support for Rockchip RK3066a boards arm: add debug uarts for rockchip rk29xx and rk3xxx series arm: Add basic clocks for Rockchip rk3066a SoCs ...

There are both new drivers as well as existing drivers that are getting converted from platform-specific code into standalone drivers using the appropriate subsystem specific interfaces. In particular, we can now have pinctrl, clk, clksource and irqchip drivers in one file per driver, without the need to call into platform specific interface, or to get called from platform specific code, as long as all information about the hardware is provided through a device tree. Most of the drivers we touch this time are for clocksource. Since now most of them are part of drivers/clocksource, I expect that we won't have to touch these again from arm-soc and can let the clocksource maintainers take care of these in the future. Another larger part of this series is specific to the exynos platform, which is seeing some significant effort in upstreaming and modernization of its device drivers this time around, which unfortunately is also the cause for the churn and a lot of the merge conflicts. There is one new subsystem that gets merged as part of this series: the reset controller interface, which is a very simple interface for taking devices on the SoC out of reset or back into reset. Patches to use this interface on i.MX follow later in this merge window, and we are going to have other platforms (at least tegra and sirf) get converted in 3.11.

For example, Tegra SoC has ~100 clocks which can be decomposed into Mux -> Div -> Gate clock types making the clock count to ~300. Also, parent change operation can not be performed on gate clock which forces to use mux clock in driver if want to change the parent. Instead aggregate the basic clock types functionality into one clock and just use this clock for all operations. This clock type re-uses the functionality of basic clock types and not limited to basic clock types but any hardware-specific implementation.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intel Lynxpoint Low Power Subsystem hosts peripherals like UART, I2C and SPI controllers. For most of these there is a configuration register that allows software to enable and disable the functional clock. Disabling the clock while the peripheral is not used saves power. In order to take advantage of this we add a new clock gate of type lpss_gate that just re-uses the ordinary clk_gate but in addition is able to enumerate the base address register of the device using ACPI. We then create a clock tree that models the Lynxpoint LPSS clocks using these gates and fixed clocks so that we can pass clock rate to the drivers as well.

The obvious fix is to remove the extraneous line from the Makefile.
