2015-11-03Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-armLinus Torvalds3-17/+6
Pull ARM updates from Russell King: "In this ARM merge, we remove more lines than we add. Changes include: - Enable imprecise aborts early, so that bus errors aren't masked until later in the boot. This has the side effect that boot loaders which provoke these aborts can cause the kernel to crash early in boot, so we install a handler to report this event around the site where these are enabled. - Remove the buggy but impossible to enable cmpxchg syscall code. - Add unwinding annotations to some assembly code. - Add support for atomic half-word exchange for ARMv6k+. - Reduce ioremap() alignment for SMP/LPAE cases where we don't need the large alignment. - Addition of an "optimal" 3G configuration for systems with 1G of RAM. - Increase vmalloc space by 128M. - Constify some SMP operations structures, which have never been writable. - Improve ARMs dma_mmap() support for mapping DMA coherent mappings into userspace. - Fix to the NMI backtrace code in the IPI case on ARM where the failing CPU gets stuck for 10s waiting for its own IPI to be delivered. - Removal of legacy PM support from the AMBA bus driver. - Another fix for the previous fix of vdsomunge" * 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: (23 commits) ARM: 8449/1: fix bug in vdsomunge swab32 macro arm: add missing of_node_put ARM: 8447/1: catch pending imprecise abort on unmask ARM: 8446/1: amba: Remove unused callbacks for legacy system PM ARM: 8443/1: Adding support for atomic half word exchange ARM: clean up TWD after previous patch ARM: 8441/2: twd: Don't set CLOCK_EVT_FEAT_C3STOP unconditionally ARM: 8440/1: remove obsolete documentation ARM: make highpte an expert option ARM: 8433/1: add a VMSPLIT_3G_OPT config option ARM: 8439/1: Fix backtrace generation when IPI is masked ARM: 8428/1: kgdb: Fix registers on sleeping tasks ARM: 8427/1: dma-mapping: add support for offset parameter in dma_mmap() ARM: 8426/1: dma-mapping: add missing range check in dma_mmap() ARM: remove user cmpxchg syscall ARM: 8438/1: Add unwinding to __clear_user_std() ARM: 8436/1: hw_breakpoint: remove unnecessary header ARM: 8434/2: Revert "7655/1: smp_twd: make twd_local_timer_of_register() no-op for nosmp" ARM: 8432/1: move VMALLOC_END from 0xff000000 to 0xff800000 ARM: 8430/1: use default ioremap alignment for SMP or LPAE ...

2015-11-03leds: netxbig: add device tree bindingSimon Guinot2-0/+114
This patch adds device tree support for the netxbig LEDs. This also introduces a additionnal DT binding for the GPIO extension bus (netxbig-gpio-ext) used to configure the LEDs. Since this bus could also be used to control other devices, then it seems more suitable to have it in a separate DT binding.

2015-11-02Merge tag 'gpio-v4.4-1' of ↵Linus Torvalds5-28/+129
git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "Here is the bulk of GPIO changes for the v4.4 development cycle. The only changes hitting outside drivers/gpio are in the pin control subsystem and these seem to have settled nicely in linux-next. Development mistakes and catfights are nicely documented in the reverts as you can see. The outcome of the ABI fight is that we're working on a chardev ABI for GPIO now, where hope to show results for the v4.5 kernel. Summary of changes: GPIO core: - Define and handle flags for open drain/open collector and open source/open emitter, also know as "single-ended" configurations. - Generic request/free operations that handle calling out to the (optional) pin control backend. - Some refactoring related to an ABI change that did not happen, yet provide useful. - Added a real-time compliance checklist. Many GPIO chips have irqchips, and need to think this over with the RT patches going upstream. - Restructure, fix and clean up Kconfig menus a bit. New drivers: - New driver for AMD Promony. - New driver for ACCES 104-IDIO-16, a port-mapped I/O card, ISA-style. Very retro. Subdriver changes: - OMAP changes to handle real time requirements. - Handle trigger types for edge and level IRQs on PL061 properly. As this hardware is very common it needs to set a proper example for others to follow. - Some container_of() cleanups. - Delete the unused MSM driver in favor of the driver that is embedded inside the pin control driver. - Cleanup of the ath79 GPIO driver used by many, many OpenWRT router targets. - A consolidated IT87xx driver replacing the earlier very specific IT8761e driver. - Handle the TI TCA9539 in the PCA953x driver. Also handle ACPI devices in this subdriver. - Drop xilinx arch dependencies as these FPGAs seem to profilate over a few different architectures.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "This is the big bulk of pin control changes for the v4.4 kernel development cycle. Development pace is high in pin control again this merge window. 28 contributors, 83 patches. It hits a few sites outside the pin control subsystem: - Device tree bindings in Documentation (as usual) - MAINTAINERS - drivers/base/* for the "init" state handling by Doug Anderson. This has been ACKed by Greg. - drivers/usb/renesas_usbhs/rcar2.c, for a dependent Renesas change in the USB subsystem. This has been ACKed by both Greg and Felipe. - arch/arm/boot/dts/sama5d2.dtsi - this should ideally have gone through the ARM SoC tree but ended up here. This time I am using Geert Uytterhoeven as submaintainer for SH PFC since the are three-four people working in parallel with new Renesas ASICs. Summary of changes: Infrastructure: - Doug Anderson wrote a patch adding an "init" state different from the "default" state for pin control state handling in the core framework. This is applied before the driver's probe() call if defined and takes precedence over "default". If both are defined, "init" will be applied *before* probe() and "default" will be applied *after* probe(). Significant subdriver improvements: - SH PFC is switched to getting GPIO ranges from the device tree ranges property on DT platforms. - Got rid of CONFIG_ARCH_SHMOBILE_LEGACY, we are all modernized. - Got rid of SH PFC hardcoded IRQ numbers. - Allwinner sunxi external interrupt through the "r" controller. - Moved the Cygnus driver to use DT-provided GPIO ranges. New drivers: - Atmel PIO4 pin controller for the SAMA4D2 family New subdrivers: - Rockchip RK3036 subdriver - Renesas SH PFC R8A7795 subdriver - Allwinner sunxi A83T PIO subdriver - Freescale i.MX7d iomux lpsr subdriver - Marvell Berlin BG4CT subdriver - SiRF Atlas 7 step B SoC subdriver - Intel Broxton SoC subdriver Apart from this, the usual slew if syntactic and semantic fixes" * tag 'pinctrl-v4.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (81 commits) pinctrl: pinconf: remove needless loop pinctrl: uniphier: guard uniphier directory with CONFIG_PINCTRL_UNIPHIER pinctrl: zynq: fix UTF-8 errors pinctrl: zynq: Initialize early pinctrl: at91: add missing of_node_put pinctrl: tegra-xusb: Correct lane mux options pinctrl: intel: Add Intel Broxton pin controller support pinctrl: intel: Allow requesting pins which are in ACPI mode as GPIOs pinctrl: intel: Add support for multiple GPIO chips sharing the interrupt drivers/pinctrl: Add the concept of an "init" state pinctrl: uniphier: set input-enable before pin-muxing pinctrl: cygnus: Add new compatible string for gpio controller driver pinctrl: cygnus: Remove GPIO to Pinctrl pin mapping from driver pinctrl: cygnus: Optional DT property to support pin mappings pinctrl: sunxi: Add irq pinmuxing to sun6i "r" pincontroller pinctrl: sunxi: Fix irq_of_xlate for the r_pio pinctrl block pinctrl: sh-pfc: Remove obsolete r8a7778 platform_device_id entry pinctrl: sh-pfc: Remove obsolete r8a7779 platform_device_id entry pinctrl: sh-pfc: Stop including <linux/platform_data/gpio-rcar.h> usb: renesas_usbhs: Remove unneeded #include <linux/platform_data/gpio-rcar.h> ...

The "compatible" property text contradicts even the example given in the MMCIF binding document itself; moreover, the Renesas MMCIF driver only matches on the generic "compatible" string and doesn't look for the SoC specific strings at all. Thus describe "renesas,sh-mmcif" as a fallback value.

2015-10-26mmc: dw_mmc-rockchip: dt-binding: Add tuning related thingsAlexandru M Stan1-0/+13
Add ciu_drive, ciu_sample clocks and default-sample-phase. This will later be used by tuning code. We do not touch ciu_drive (and by extension define default-drive-phase). Drive phase is mostly used to define minimum hold times, while one could write some code to determine what phase meets the minimum hold time (ex 10 degrees) this will not work with the current clock phase framework (which floors angles, so we'll get 0 deg, and there's no way to know what resolution the floors happen at). We assume that the default drive angles set by the hardware are good enough.

2015-10-26mmc: core: Remove MMC_CLKGATEUlf Hansson1-10/+0
MMC_CLKGATE was once invented to save power by gating the bus clock at request inactivity. At that time it served its purpose. The modern way to deal with power saving for these scenarios, is by using runtime PM. Nowadays, several host drivers have deployed runtime PM, but for those that haven't and which still cares power saving at request inactivity, it's certainly time to deploy runtime PM as it has been around for several years now. To simplify code to mmc core and thus decrease maintenance efforts, this patch removes all code related to MMC_CLKGATE.

In 5388a6b266 ("ARM: SMP: Always enable clock event broadcast support") Russell noted that "the TWD local timers are unable to wake up the CPU when it is placed into a low power mode". However, some platforms do not stop the TWD block in low-power mode, and can thus use the TWD timer in one-shot mode, without setting up a broadcast device. Make the driver check for the "always-on" boolean property, and set the CLOCK_EVT_FEAT_C3STOP flag accordingly.

It is customary for GPIO controllers to support open drain/collector and open source/emitter configurations. Add standard GPIO line flags to account for this and augment the documentation to say that these are the most generic bindings. Several people approached me to add new flags to the lines, and this makes sense, but let's first bind up the most common cases before we start to add exotic stuff. Thanks to H. Nikolaus Schaller for ideas on how to encode single-ended wiring such as open drain/source and open collector/emitter.
