Pull clock framework update from Michael Turquette: "The common clock framework changes for 3.9 are almost entirely fixes. None are dire enough to be Cc'd to stable which may be interpreted to mean that users of the framework are reaching stability. Lots of new adoption of this framework is via DeviceTree data and that comes through the respective architecture and platform trees instead of through the clk framework tree. Two new features are improved debugfs output and an improvement to how DT clocks are initialized by reusing a common method." * tag 'clk-for-linus' of git://git.linaro.org/people/mturquette/linux: (25 commits) clk: sunxi: remove stale Makefile entry clk: vexpress: Use common of_clk_init() function clk: zynq: Use common of_clk_init() function clk: vt8500: Use common of_clk_init() function clk: highbank: Use common of_clk_init() function clk: sunxi: Use common of_clk_init() function clk: add common of_clk_init() function clk: Deduplicate exit code in clk_set_rate clk: beautify Makefile clk-divider: fix macros clk: prima2: enable dt-binding clkdev mapping clk: mxs: Index is always positive clk: max77686: Avoid double free at remove time clk: remove exported function from __init section clk: vt8500: Add support for WM8750/WM8850 PLL clocks clk: vt8500: Fix division-by-0 when requested rate=0 clk: vt8500: Fix device clock divisor calculations clk: vt8500: Fix error in PLL calculations on non-exact match. clk: max77686: Remove unnecessary NULL checking for container_of() clk: JSON debugfs clock tree summary ...

2013-01-23clk: x86: add support for Lynxpoint LPSS clocksMika Westerberg5-0/+224
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 clk_lookup entry is dropped at remove time by a call to clkdev_drop(). That function frees the entry, which is also freed by the driver core as it has been allocated through devm_kzalloc().

The new Broadcom platform is contributed by Christian Daudt. Highbank has grown support for Calxeda's next generation of hardware, ECX-2000. clps711x has seen a lot of cleanup from Alexander Shiyan, and he's also taken on maintainership of the platform.

Pull driver core updates from Greg Kroah-Hartman: "Here's the large driver core updates for 3.8-rc1. The biggest thing here is the various __dev* marking removals. This is going to be a pain for the merge with different subsystem trees, I know, but all of the patches included here have been ACKed by their various subsystem maintainers, as they wanted them to go through here. If this is too much of a pain, I can pull all of them out of this tree and just send you one with the other fixes/updates and then, after 3.8-rc1 is out, do the rest of the removals to ensure we catch them all, it's up to you. The merges should all be trivial, and Stephen has been doing them all in linux-next for a few weeks now quite easily. Other than the __dev* marking removals, there's nothing major here, some firmware loading updates and other minor things in the driver core.

2012-12-10clk: introduce optional disable_unused callbackMike Turquette1-2/+11
Some gate clocks have special needs which must be handled during the disable-unused clocks sequence. These needs might be driven by software due to the fact that we're disabling a clock outside of the normal clk_disable path and a clk's enable_count will not be accurate. On the other hand a specific hardware programming sequence might need to be followed for this corner case. This change is needed for the upcoming OMAP port to the common clock framework. Specifically, it is undesirable to treat the disable-unused path identically to the normal clk_disable path since other software layers are involved. In this case OMAP's clockdomain code throws WARNs and bails early due to the clock's enable_count being set to zero. A custom callback mitigates this problem nicely.

2012-12-04clk: ux500: fix bit errorLinus Walleij1-1/+1
This fixes a bit error in the U8500 clock implementation: the unused p2_pclk12 registered at bit 12 in periphereral group 6 was defined as using bit 11 rather than bit 12. When walking over and disabling the unused clocks in the tree at late init time, p2_pclk12 was disabled, by effectively clearing the but for p2_pclk11 instead of bit 12 as it should have, thus disabling gpio block 6 and 7.
