2013-08-07pinctrl: sunxi: Add spinlocksMaxime Ripard2-3/+54
The current code use no locking at all, which is obviously not that great and can lead to concurrency issues, especially with the newer SMP SoCs from Allwinner. Add some locking where it's needed.

2013-08-07pinctrl: sunxi: Fix gpio_set behaviourMaxime Ripard1-1/+7
The current gpio_set function is ignoring the previous value set in the GPIO value register, which leads in erasing the values already set for the other GPIOs in the same bank when setting the value of a given GPIO. Add the usual read/mask/write pattern to fix this brown paper bag bug. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Linus Walleij <linus.walleij@stericsson.com>

Pull pin control changes from Linus Walleij: - A large slew of improvements of the Genric pin configuration support, and deployment in four different platforms: Rockchip, Super-H PFC, ABx500 and TZ1090. Support BIAS_BUS_HOLD, get device tree parsing and debugfs support into shape. - We also have device tree support with generic naming conventions for the generic pin configuration. - Delete the unused and confusing direct pinconf API. Now state transitions is *the* way to control pins and multiplexing. - New drivers for Rockchip, TZ1090, and TZ1090 PDC. - Two pin control states related to power management are now handled in the device core: "sleep" and "idle", removing a lot of boilerplate code in drivers. We do not yet know if this is the final word for pin PM, but it already make things a lot easier to handle. - Handle sparse GPIO ranges passing a list of disparate pins, and utilize these in the new BayTrail (x86 Atom SoC) driver. - Make the sunxi (AllWinner) driver handle external interrupts. - Make it possible for pinctrl-single to handle the case where several pins are managed by a single register, and augment it to handle sleep modes. - Cleanups and improvements for the abx500 drivers. - Move Sirf pin control drivers to their own directory, support save/restore of context and add support for the SiRFatlas6 SoC. - PMU muxing for the Dove pinctrl driver. - Finalization and support for VF610 in the i.MX6 pinctrl driver. - Smoothen out various Exynos rough edges. - Generic cleanups of various kinds. * tag 'pinctrl-for-v3.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (82 commits) pinctrl: vt8500: wmt: remove redundant dev_err call in wmt_pinctrl_probe() pinctrl: remove bindings for pinconf options needing more thought pinctrl: remove slew-rate parameter from tz1090 pinctrl: set unit for debounce time pinconfig to usec pinctrl: more clarifications for generic pull configs pinctrl: rip out the direct pinconf API pinctrl-tz1090-pdc: add TZ1090 PDC pinctrl driver pinctrl-tz1090: add TZ1090 pinctrl driver pinctrl: samsung: Staticize drvdata_list pinctrl: rockchip: Add missing irq_gc_unlock() call before return error pinctrl: abx500: rework error path pinctrl: abx500: suppress hardcoded value pinctrl: abx500: factorize code pinctrl: abx500: fix abx500_gpio_get() pinctrl: abx500: fix abx500_pin_config_set() pinctrl: abx500: Add device tree support sh-pfc: Guard DT parsing with #ifdef CONFIG_OF pinctrl: add Intel BayTrail GPIO/pinctrl support pinctrl: fix pinconf_ops::pin_config_dbg_parse_modify kerneldoc pinctrl: Staticize local symbols ...

2013-06-25pinctrl: st: Add pinctrl and pinconf support.Srinivas KANDAGATLA3-0/+1410
This patch add pinctrl support to ST SoCs. About hardware: ST Set-Top-Box parts have two blocks called PIO and PIO-mux which handle pin configurations. Each multi-function pin is controlled, driven and routed through the PIO multiplexing block. Each pin supports GPIO functionality (ALT0) and multiple alternate functions(ALT1 - ALTx) that directly connect the pin to different hardware blocks. When a pin is in GPIO mode, Output Enable (OE), Open Drain(OD), and Pull Up (PU) are driven by the related PIO block. Otherwise the PIO multiplexing block configures these parameters and retiming the signal. About driver: This pinctrl driver manages both PIO and PIO-mux block using pinctrl, pinconf, pinmux, gpio subsystems. All the pinctrl related config information can only come from device trees.

2013-06-25pinctrl: rip out the direct pinconf APILinus Walleij1-174/+0
From the inception ot the pin config API there has been the possibility to get a handle at a pin directly and configure its electrical characteristics. For this reason we had: int pin_config_get(const char *dev_name, const char *name, unsigned long *config); int pin_config_set(const char *dev_name, const char *name, unsigned long config); int pin_config_group_get(const char *dev_name, const char *pin_group, unsigned long *config); int pin_config_group_set(const char *dev_name, const char *pin_group, unsigned long config); After the introduction of the pin control states that will control pins associated with devices, and its subsequent introduction to the device core, as well as the introduction of pin control hogs that can set up states on boot and optionally also at sleep, this direct pin control API is a thing of the past. As could be expected, it has zero in-kernel users. Let's delete this API and make our world simpler.

2013-06-19ARM: EXYNOS: Select PINCTRL_EXYNOS for exynos4/5 at chip levelDoug Anderson1-2/+3
Previously if you had MACH_EXYNOS5_DT but not MACH_EXYNOS4_DT you'd be missing the pincontrol definitions. Move PINCTRL selects to the arch level since we should be enabling the code for all exynos variants. Update the PINCTRL descriptions to indicate that PINCTRL_EXYNOS is not for exynos5440. Also add basic dependencies for the PINCTRL_EXYNOS kernel config.

2013-06-18pinctrl: add Intel BayTrail GPIO/pinctrl supportMathias Nyman3-0/+556
Add support for gpio on Intel BayTrail platforms. BayTrail supports 3 banks of gpios called SCORE, NCORE ans SUS with 102, 28 and 44 gpio pins. Supports gpio interrupts and ACPI gpio events Pins may be muxed to alternate function instead of gpio by firmware. This driver does not touch the pin muxing and expect firmare to set pin muxing and pullup/down properties properly.
