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> ...

2015-11-01gpio: fix up SPI submenuLinus Walleij1-16/+18
- Relax dependencies on SPI_MASTER for drivers in the SPI menu that already has this dependency. - Move out the expander that would be hidden for I2C access if SPI_MASTER was not selected. Tentatively create a separate menu for this. - Move the ZX SoC driver to memory-mapped drivers, this must be a mistake and only worked because the system has an SPI master enabled at the same time.
