2013-07-29sh-pfc: Support pins not associated with a GPIO portLaurent Pinchart5-18/+49
Pins with selectable functions but without a GPIO port can't be named PORT_# or GP_#_#. Add a SH_PFC_PIN_NAMED macro to declare such pins in the pinmux pins array, naming them with the PIN_ prefix followed by the pin physical position. In order to make sure not to register those pins as GPIOs, add a SH_PFC_PIN_CFG_NO_GPIO pin flag to denote pins without a GPIO port.

2013-07-29sh-pfc: Replace pinmux_enum_id typedef with u16Laurent Pinchart21-46/+37
The typedef only conceals the real variable type without bringing any additional value (see Documentation/CodingStyle, section 5.b). Moreover, it polutes the pinmux namespace.

2013-07-29sh-pfc: Don't overallocate memory for the GPIO chip pins arrayLaurent Pinchart1-2/+2
The GPIO driver uses an array of sh_pfc_gpio_pin structures to store per-GPIO pin data. The array size is miscomputed at allocation time by using the number of the last pin instead of the number of pins. When the pin space contains holes this leads to memory overallocation. Fix it.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl 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 ...

2013-06-24sh-pfc: Guard DT parsing with #ifdef CONFIG_OFLaurent Pinchart1-0/+4
Fix a compilation error caused by pinconf_generic_parse_dt_config() not being defined on !CONFIG_OF platforms by guarding the whole DT node parsing code with #ifdef CONFIG_OF. Defining a pinconf_generic_parse_dt_config() on !CONFIG_OF would have been possible as well, but would have resulted in a larger code size on !CONFIG_OF platforms (such as arch/sh).
