2013-04-12ARM i.MX53: tve_di clock is not part of the CCM, but of TVEPhilipp Zabel1-1/+0

These two clocks connect to external pins and can be muxed to various internal clocks. They are typically used either for debugging or to provide clocks to external chips (eg audio codecs). Currently only the selectable clocks that already exist in the clock tree have been added.

2013-04-12dt: describe base reset signal bindingStephen Warren1-0/+75
This binding is intended to represent the hardware reset signals present internally in most IC (SoC, FPGA, ...) designs. It consists of a binding for a reset controller device (provider), and a pair of properties, "resets" and "reset-names", to link a device node (consumer) to its reset controller via phandle, similarly to the clock and interrupt bindings. The reset controller has all information necessary to reset the consumer device. That could be provided via device tree, or it could be implemented in hardware. The aim is to enable device drivers to request a framework API to issue a reset simply by providing their struct device pointer as the most common case.

Commit 18a3870 (ACPI / PM: Expose lists of device power resources to user space) exposed the lists of ACPI power resources associated with power states of ACPI devices, but it didn't expose the lists of ACPI wakeup power resources, which also is necessary to get the full picture of dependencies between ACPI devices and power resources.

2013-04-10gpio/omap: force restore if context loss is not detectableJon Hunter1-2/+5
When booting with device-tree the function pointer for detecting context loss is not populated. Ideally, the pm_runtime framework should be enhanced to allow a means for reporting context/state loss and we could avoid populating such function pointers altogether. In the interim until a generic non-device specific solution is in place, force a restore of the gpio bank when enabling the gpio controller. Adds a new device-tree property for the OMAP GPIO controller to indicate if the GPIO controller is located in a power-domain that never loses power and hence will always maintain its logic state.

2013-04-10cpufreq: exynos: Add cpufreq driver for exynos5440Amit Daniel Kachhap1-0/+28
This patch adds dvfs support for exynos5440 SOC. This soc has 4 cores and they scale at same frequency. The nature of exynos5440 clock controller is different from previous exynos controllers so not using the common exynos cpufreq framework. The major difference being interrupt notification for frequency change. Also, OPP library is used for device tree parsing to get different parameters like frequency, voltage etc. Since the opp library sorts the frequency table in ascending order so they are again re-arranged in descending order. This will have one-to-one mapping with the clock controller state management logic.

2013-04-09ext4: introduce reserved spaceLukas Czerner1-0/+11
Currently in ENOSPC condition when writing into unwritten space, or punching a hole, we might need to split the extent and grow extent tree. However since we can not allocate any new metadata blocks we'll have to zero out unwritten part of extent or punched out part of extent, or in the worst case return ENOSPC even though use actually does not allocate any space. Also in delalloc path we do reserve metadata and data blocks for the time we're going to write out, however metadata block reservation is very tricky especially since we expect that logical connectivity implies physical connectivity, however that might not be the case and hence we might end up allocating more metadata blocks than previously reserved. So in future, metadata reservation checks should be removed since we can not assure that we do not under reserve. And this is where reserved space comes into the picture. When mounting the file system we slice off a little bit of the file system space (2% or 4096 clusters, whichever is smaller) which can be then used for the cases mentioned above to prevent costly zeroout, or unexpected ENOSPC. The number of reserved clusters can be set via sysfs, however it can never be bigger than number of free clusters in the file system. Note that this patch fixes the failure of xfstest 274 as expected.

From Stephen Warren <swarren@wwwdotorg.org>: ARM: tegra: clock driver development This branch contains most fixes and enhancements to the Tegra common clock driver. The main new feature is a driver for Tegra114, which coupled with later device tree changes enables many devices on that chip, such as MMC, I2C, etc. This branch depends on a patch in: git://git.linaro.org/people/mturquette/linux.git clk-for-3.10 Mike has stated that this branch is stable, and is aware of this dependency and merge. Mike's branch is based on v3.9-rc3, which includes a USB change which causes problems on Tegra. That problem was fixed in v3.9-rc4. Hence, this branch pulls in v3.9-rc4 to ensure bisectability as much as possible. This branch is based on v3.9-rc4, followed by a merge of previous Tegra "soc" pull request, followed by a merge of clk-for-3.10. * tag 'tegra-for-3.10-clk' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra: clk: tegra: fix enum tegra114_clk to match binding clk: tegra: Remove forced clk_enable of uartd ARM: dt: Add references to tegra_car clocks clk: tegra: devicetree match for nvidia,tegra114-car clk: tegra: Implement clocks for Tegra114 ARM: tegra: Define Tegra114 CAR binding clk: tegra: Workaround for Tegra114 MSENC problem clk: tegra: Add flags to tegra_clk_periph() clk: tegra: Add new fields and PLL types for Tegra114 clk: tegra: move from a lock bit idx to a lock mask clk: tegra: Add PLL post divider table clk: tegra: introduce TEGRA_PLL_HAS_LOCK_ENABLE clk: tegra: Add TEGRA_PLL_BYPASS flag clk: tegra: Refactor PLL programming code clk: tegra: provide dummy cpu car ops clk: tegra: defer application of init table clk: tegra: Fix cdev1 and cdev2 IDs clk: tegra: Make gr2d and gr3d clocks children of pll_c clk: tegra: Export peripheral reset functions clk: tegra: Fix periph_clk_to_bit macro Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2013-04-09pinctrl: add pinctrl driver for imx6dlShawn Guo1-0/+38
The imx6dl is a derivative of imx6q with very limited difference. These two SoCs are so compatible that they can be handled as one platform in software. That said, we will not have target SOC_IMX6DL but just reusing SOC_IMX6Q. That's why the pinctrl-imx6dl driver is added here with symbol PINCTRL_IMX6Q controlling the build of it.

2013-04-09pinctrl: imx: move hard-coding data into device treeShawn Guo5-4479/+11
Currently, all imx pinctrl drivers maintain a big array of struct imx_pin_reg which hard-codes data like register offset and mux mode setting for each pin function. Every time a new imx SoC support is added, we need to add such a big mount of data. With moving to single kernel build, it's only matter of time to be blamed on memory consuming. With DTC pre-processor support in place, the patch moves all these data into device tree by redefining the PIN_FUNC_ID in imxXX-pinfunc.h and changing the PIN_FUNC_ID parsing code a little bit. The pin id gets re-numbered based on mux register offset, or config register offset if the pin has no mux register, so that kernel can identify the pin id from register offsets provided by device tree. As a bonus point of the change, those arbitrary magic numbers standing for particular PIN_FUNC_ID in device tree sources are now replaced by macros to improve the readability of dts files.
