This patch updates i.MX51 CPU node: - Alias for CPU is added to allow using this node in the parent DTS files. - Removed useless "clock_names" property. - "clock-latency" value increased to safe using with 32 kHz OSC. - Defined operating points voltages and "voltage tolerance" properties. Values are safe for both commercial and industrial CPU variants. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

The device tree specification recommends that generic name should be used for nodes. So instead of naming those fixed regulator nodes arbitrarily, let's use the generic name 'regulator@num' for those nodes. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

Currently, all pinctrl setting nodes are defined in <soc>.dtsi, so that boards that share the same pinctrl setting do not have to define it time and time again in <board>.dts. However, along with the devices and use cases being added continuously, the pinctrl setting nodes under iomuxc becomes more than expected. This bloats device tree blob for particular board unnecessarily since only a small subset of those pinctrl setting nodes will be used by the board. It impacts not only the DTB file size but also the run-time device tree lookup efficiency. The patch moves all the pinctrl data into individual boards as needed. With the changes, the pinctrl setting nodes becomes local to particular board, and it makes no sense to continue numbering the setting for given peripheral. Thus, all the pinctrl phandler name gets updated to have only peripheral name in there. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Fugang Duan <B38611@freescale.com>

Pull parisc updates from Helge Deller: "The three major changes in this patchset is a implementation for flexible userspace memory maps, cache-flushing fixes (again), and a long-discussed ABI change to make EWOULDBLOCK the same value as EAGAIN. parisc has been the only platform where we had EWOULDBLOCK != EAGAIN to keep HP-UX compatibility. Since we will probably never implement full HP-UX support, we prefer to drop this compatibility to make it easier for us with Linux userspace programs which mostly never checked for both values. We don't expect major fall-outs because of this change, and if we face some, we will simply rebuild the necessary applications in the debian archives" * 'parisc-3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: add flexible mmap memory layout support parisc: Make EWOULDBLOCK be equal to EAGAIN on parisc parisc: convert uapi/asm/stat.h to use native types only parisc: wire up sched_setattr and sched_getattr parisc: fix cache-flushing parisc/sti_console: prefer Linux fonts over built-in ROM fonts

HPFS needs to load 4 consecutive 512-byte sectors when accessing the directory nodes or bitmaps. We can't switch to 2048-byte block size because files are allocated in the units of 512-byte sectors. Previously, the driver would allocate a 2048-byte area using kmalloc, copy the data from four buffers to this area and eventually copy them back if they were modified. In the current implementation of the buffer cache, buffers are allocated in the pagecache. That means that 4 consecutive 512-byte buffers are stored in consecutive areas in the kernel address space. So, we don't need to allocate extra memory and copy the content of the buffers there. This patch optimizes the code to avoid copying the buffers. It checks if the four buffers are stored in contiguous memory - if they are not, it falls back to allocating a 2048-byte area and copying data there.

Previously, hpfs scanned all bitmaps each time the user asked for free space using statfs. This patch changes it so that hpfs scans the bitmaps only once, remembes the free space and on next invocation of statfs it returns the value instantly. New versions of wine are hammering on the statfs syscall very heavily, making some games unplayable when they're stored on hpfs, with load times in minutes. This should be backported to the stable kernels because it fixes user-visible problem (excessive level load times in wine).

Add support for the flexible mmap memory layout (as described in http://lwn.net/Articles/91829). This is especially very interesting on parisc since we currently only support 32bit userspace (even with a 64bit Linux kernel). Signed-off-by: Helge Deller <deller@gmx.de>

On Linux, only parisc uses a different value for EWOULDBLOCK which causes a lot of troubles for applications not checking for both values. Since the hpux compat is long dead, make EWOULDBLOCK behave the same as all other architectures. Signed-off-by: Guy Martin <gmsoft@tuxicoman.be> Signed-off-by: Helge Deller <deller@gmx.de>

The stat.h header file is exported to userspace. Some userspace applications failed to compile due to missing/unknown types, so we better convert it to use native types only (like it's done on other architectures too). Signed-off-by: Helge Deller <deller@gmx.de>

This commit: f8dae006: parisc: Ensure full cache coherency for kmap/kunmap caused negative caching side-effects, e.g. hanging processes with expect and too many inequivalent alias messages from flush_dcache_page() on Debian 5 systems.

The built-in ROM fonts lack many necessary ASCII characters, which is why it makes sens to prefer the Linux fonts instead if they are available. This makes consoles on STI graphics cards which are not supported by the stifb driver (e.g. Visualize FXe) looks much nicer.

Pull ARM SoC fixes from Olof Johansson: "Here's a set of patches for (hopefully) -rc1. Some of them are fixes, but a good number of them also do things such as enable new drivers in the defconfigs for platforms that have such devices, increases coverage of the multiplatform defconfig and some DTS changes that plumbs up some of the devices that now have bindings and driver support. The commit dates are recent; we've mostly collected these fixes in the last few days but I also had to rebuild the branch yesterday to sort out some internal conflicts which reset the timestamps. The changes should have been tested by each platform maintainer already (and few of them have cross-platform impact) so I'm personally not too concerned by it at this time" * tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (23 commits) ARM: multi_v7_defconfig: remove redundant entries and re-enable TI_EDMA ARM: multi_v7_defconfig: add mvebu drivers clocksource: kona: Add basic use of external clock drivers: bus: fix CCI driver kcalloc call parameters swap ARM: dts: bcm28155-ap: Fix Card Detection GPIO ARM: multi_v7_defconfig: Select CONFIG_AT803X_PHY ARM: keystone: config: fix build warning when CONFIG_DMADEVICES is not set MAINTAINERS: ARM: SiRF: use regex patterns to involve all SiRF drivers ARM: dts: zynq: Add SDHCI nodes ARM: hisi: don't select SMP ARM: tegra: rebuild tegra_defconfig to add DEBUG_FS ARM: multi_v7: copy most options from tegra_defconfig ARM: iop32x: fix power off handling for the EM7210 board ARM: integrator: restore static map on the CP ARM: msm_defconfig: Enable MSM clock drivers ARM: dts: msm: Add clock controller nodes and hook into uart ARM: OMAP4+: move errata initialization to omap4_pm_init_early ARM: OMAP4460: cpuidle: Extend PM_OMAP4_ROM_SMP_BOOT_ERRATUM_GICD on cpuidle ARM: mvebu: fix compilation warning on Armada 370 (i.e. non-SMP) ARM: shmobile: r8a7790.dtsi: ficx i2c[0-3] clock reference ...
