2015-02-02clk: Add rate constraints to clocksTomeu Vizoso3-3/+46
Adds a way for clock consumers to set maximum and minimum rates. This can be used for thermal drivers to set minimum rates, or by misc. drivers to set maximum rates to assure a minimum performance level. Changes the signature of the determine_rate callback by adding the parameters min_rate and max_rate.

2015-02-02clk: remove clk-private.hMichael Turquette1-237/+0
Private clock framework data structures should be private, surprisingly. Now that all platforms and drivers have been updated to remove static initializations of struct clk and struct clk_core objects and all references to clk-private.h have been removed we can move the definitions of these structures into drivers/clk/clk.c and delete the header. Additionally the ugly DEFINE_CLK macros have been removed. Those were used for static definitions of struct clk objects. That practice is no longer allowed. Finally __clk_init is staticized as it is no longer declared in any header. Reviewed-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Michael Turquette <mturquette@linaro.org>

2015-02-02clk: Make clk API return per-user struct clk instancesTomeu Vizoso2-13/+34
Moves clock state to struct clk_core, but takes care to change as little API as possible. struct clk_hw still has a pointer to a struct clk, which is the implementation's per-user clk instance, for backwards compatibility. The struct clk that clk_get_parent() returns isn't owned by the caller, but by the clock implementation, so the former shouldn't call clk_put() on it. Because some boards in mach-omap2 still register clocks statically, their clock registration had to be updated to take into account that the clock information is stored in struct clk_core now.

2015-01-30clk: ti: add omap3 legacy clock dataTero Kristo1-0/+12
Introduces omap3 legacy clock data under clock driver. The clock data is also in new format, which makes it possible to get rid of the clk-private.h header. This patch also introduces SoC specific init functions that shall be called from the low level init. The data format used in this file has two possible evolution paths; it can either be removed completely once no longer needed, or it will be possible to retain the format and modify the TI clock driver to be a loadable module at some point. The actual path to be followed will be decided later. Signed-off-by: Tero Kristo <t-kristo@ti.com> Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Michael Turquette <mturquette@linaro.org>

git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into clk-next The two big changes are the additional of the watchdog clock, which we currently only "fake" as the clock gate control is living in a very strange place, but the watchdog driver needs to read the clock rate from it and the setting of rk3288 plls to slow mode upon suspend. Other than that some more exported clocks and a CLK_SET_RATE_PARENT flag for the uart clocks.

These modules don't need to include clk-private.h. Replace the include with clk.h because these modules are clock consumers and also include clk-provider.h in clk/ti.h because struct clk_hw_omap has a struct clk_hw embedded in it.

This new function is similar to clk_set_parent(), except that it doesn't actually change the parent. It merely checks that the given parent clock can be a parent for the given clock. A situation where this is useful is to check that a particular setup is valid before switching to it. One specific use-case for this is atomic modesetting in the DRM framework where setting a mode is divided into a check phase where a given configuration is validated before applying changes to the hardware.

Pull virtio fixes from Michael S Tsirkin: "virtio 1.0 related fixes Most importantly, this fixes using virtio_pci as a module. Further, the big virtio 1.0 conversion missed a couple of places. This fixes them up. This isn't 100% sparse-clean yet because on many architectures get_user triggers sparse warnings when used with __bitwise tag (when same tag is on both pointer and value read). I posted a patchset to fix it up by adding __force on all arches that don't already have it (many do), when that's merged these warnings will go away" * tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost: virtio_pci: restore module attributes mic/host: fix up virtio 1.0 APIs vringh: update for virtio 1.0 APIs vringh: 64 bit features tools/virtio: add virtio 1.0 in vringh_test tools/virtio: add virtio 1.0 in virtio_test tools/virtio: enable -Werror tools/virtio: 64 bit features tools/virtio: fix vringh test tools/virtio: more stubs virtio: core support for config generation virtio_pci: add VIRTIO_PCI_NO_LEGACY virtio_pci: move probe to common file virtio_pci_common.h: drop VIRTIO_PCI_NO_LEGACY virtio_config: fix virtio_cread_bytes virtio: set VIRTIO_CONFIG_S_FEATURES_OK on restore

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull more ACPI and power management updates from Rafael Wysocki: "These are regression fixes (leds-gpio, ACPI backlight driver, operating performance points library, ACPI device enumeration messages, cpupower tool), other bug fixes (ACPI EC driver, ACPI device PM), some cleanups in the operating performance points (OPP) framework, continuation of CONFIG_PM_RUNTIME elimination, a couple of minor intel_pstate driver changes, a new MAINTAINERS entry for it and an ACPI fan driver change needed for better support of thermal management in user space. Specifics: - Fix a regression in leds-gpio introduced by a recent commit that inadvertently changed the name of one of the properties used by the driver (Fabio Estevam). - Fix a regression in the ACPI backlight driver introduced by a recent fix that missed one special case that had to be taken into account (Aaron Lu). - Drop the level of some new kernel messages from the ACPI core introduced by a recent commit to KERN_DEBUG which they should have used from the start and drop some other unuseful KERN_ERR messages printed by ACPI (Rafael J Wysocki). - Revert an incorrect commit modifying the cpupower tool (Prarit Bhargava). - Fix two regressions introduced by recent commits in the OPP library and clean up some existing minor issues in that code (Viresh Kumar). - Continue to replace CONFIG_PM_RUNTIME with CONFIG_PM throughout the tree (or drop it where that can be done) in order to make it possible to eliminate CONFIG_PM_RUNTIME (Rafael J Wysocki, Ulf Hansson, Ludovic Desroches). There will be one more "CONFIG_PM_RUNTIME removal" batch after this one, because some new uses of it have been introduced during the current merge window, but that should be sufficient to finally get rid of it. - Make the ACPI EC driver more robust against race conditions related to GPE handler installation failures (Lv Zheng). - Prevent the ACPI device PM core code from attempting to disable GPEs that it has not enabled which confuses ACPICA and makes it report errors unnecessarily (Rafael J Wysocki). - Add a "force" command line switch to the intel_pstate driver to make it possible to override the blacklisting of some systems in that driver if needed (Ethan Zhao). - Improve intel_pstate code documentation and add a MAINTAINERS entry for it (Kristen Carlson Accardi). - Make the ACPI fan driver create cooling device interfaces witn names that reflect the IDs of the ACPI device objects they are associated with, except for "generic" ACPI fans (PNP ID "PNP0C0B"). That's necessary for user space thermal management tools to be able to connect the fans with the parts of the system they are supposed to be cooling properly.

2014-12-18mm: cma: split cma-reserved in dmesg logPintu Kumar1-0/+1
When the system boots up, in the dmesg logs we can see the memory statistics along with total reserved as below. Memory: 458840k/458840k available, 65448k reserved, 0K highmem When CMA is enabled, still the total reserved memory remains the same. However, the CMA memory is not considered as reserved. But, when we see /proc/meminfo, the CMA memory is part of free memory. This creates confusion. This patch corrects the problem by properly subtracting the CMA reserved memory from the total reserved memory in dmesg logs. Below is the dmesg snapshot from an arm based device with 512MB RAM and 12MB single CMA region. Before this change: Memory: 458840k/458840k available, 65448k reserved, 0K highmem After this change: Memory: 458840k/458840k available, 53160k reserved, 12288k cma-reserved, 0K highmem Signed-off-by: Pintu Kumar <pintu.k@samsung.com> Signed-off-by: Vishnu Pratap Singh <vishnu.ps@samsung.com> Acked-by: Michal Nazarewicz <mina86@mina86.com> Cc: Rafael Aquini <aquini@redhat.com> Cc: Jerome Marchand <jmarchan@redhat.com> Cc: Marek Szyprowski <m.szyprowski@samsung.com> Cc: Joonsoo Kim <iamjoonsoo.kim@lge.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
