The only valuable information a special callback can derive from mvebu_mpp_ctrl passed to it, is the pin id. Instead of passing the struct, pass the pid directly.

2014-02-25pinctrl: mvebu: identify generic controls by nameSebastian Hesselbarth

2014-02-25pinctrl: mvebu: count unnamed controls and allocate name bufferSebastian Hesselbarth
pinctrl-mvebu allows SoCs to pass unnamed controls that will get an auto-generated name of "mpp<PIN#>". Currently, we are allocating name buffers on a per-control basis while looping over passed controls. This counts the total number of unnamed controls and allocates a global name buffer instead. The new buffer is then used while assigning controls to pinctrl groups later.

For some silicons, the pin configuration register can control the output of the pin when the pad including the pin enter low power mode. For example, the pin can be "Drive 1", "Drive 0", "Float" when the pad including the pin enter low power mode.

2014-02-06pinctrl: do not init debugfs entries for unimplemented functionalitiesFlorian Vaussard
Commit c420619 "pinctrl: pinconf: remove checks on ops->pin_config_get" removed the check on (ops != NULL) when performing pinconf_pins_show() or pinconf_groups_show(). As these entries are always enabled, even if pinconf is not supported, reading will result in an oops due to NULL ops. Instead of checking for ops, remove the corresponding debugfs entries if pinconf and/or pinmux are not implemented. Tested on OMAP3 (pinctrl-single).

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO tree bulk changes from Linus Walleij: "A big set this merge window, as we have much going on in this subsystem. The changes to other subsystems (notably a slew of ARM machines as I am doing away with their custom APIs) have all been ACKed to the extent possible. Major changes this time: - Some core improvements and cleanups to the new GPIO descriptor API. This seems to be working now so we can start the exodus to this API, moving gradually away from the global GPIO numberspace. - Incremental improvements to the ACPI GPIO core, and move the few GPIO ACPI clients we have to the GPIO descriptor API right *now* before we go any further. We actually managed to contain this *before* we started to litter the kernel with yet another hackish global numberspace for the ACPI GPIOs, which is a big win. - The RFkill GPIO driver and all platforms using it have been migrated to use the GPIO descriptors rather than fixed number assignments. Tegra machine has been migrated as part of this. - New drivers for MOXA ART, Xtensa GPIO32 and SMSC SCH311x. Those should be really good examples of how I expect a nice GPIO driver to look these days. - Do away with custom GPIO implementations on a major part of the ARM machines: ks8695, lpc32xx, mv78xx0. Make a first step towards the same in the horribly convoluted Samsung S3C include forest. We expect to continue to clean this up as we move forward. - Flag GPIO lines used for IRQ on adnp, bcm-kona, em, intel-mid and lynxpoint. This makes the GPIOlib core aware that a certain GPIO line is used for IRQs and can then enforce some semantics such as disallowing a GPIO line marked as in use for IRQ to be switched to output mode. - Drop all use of irq_set_chip_and_handler_name(). The name provided in these cases were just unhelpful tags like "mux" or "demux". - Extend the MCP23s08 driver to handle interrupts. - Minor incremental improvements for rcar, lynxpoint, em 74x164 and msm drivers. - Some non-urgent bug fixes here and there, duplicate #includes and that usual kind of cleanups" Fix up broken Kconfig file manually to make this all compile. * tag 'gpio-v3.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (71 commits) gpio: mcp23s08: fix casting caused build warning gpio: mcp23s08: depend on OF_GPIO gpio: mcp23s08: Add irq functionality for i2c chips ARM: S5P[v210|c100|64x0]: Fix build error gpio: pxa: clamp gpio get value to [0,1] ARM: s3c24xx: explicit dependency on <plat/gpio-cfg.h> ARM: S3C[24|64]xx: move includes back under <mach/> scope Documentation / ACPI: update to GPIO descriptor API gpio / ACPI: get rid of acpi_gpio.h gpio / ACPI: register to ACPI events automatically mmc: sdhci-acpi: convert to use GPIO descriptor API ARM: s3c24xx: fix build error gpio: f7188x: set can_sleep attribute gpio: samsung: Update documentation gpio: samsung: Remove hardware.h inclusion gpio: xtensa: depend on HAVE_XTENSA_GPIO32 gpio: clps711x: Enable driver compilation with COMPILE_TEST gpio: clps711x: Use of_match_ptr() net: rfkill: gpio: convert to descriptor-based GPIO interface leds: s3c24xx: Fix build failure ...
2014-01-21mfd/pinctrl: Delete platform data headerLinus Walleij
This deletes the special AB8500 GPIO platform data passing header and merges the few remaining contents down into the abx500 pinctrl driver which handles the abx500 GPIO device. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>

This reverts commit f6308b36c411 (ACPI: Add BayTrail SoC GPIO and LPSS ACPI IDs), because it causes the Alan Cox' ASUS T100TA to "crash and burn" during boot if the Baytrail pinctrl driver is compiled in.

2014-01-16pinctrl: capri: add dependency on OFLinus Walleij
As this driver is using pinconf_generic_dt_node_to_map_pin() it needs to depend on OF so as not to cause build problems on archs that do not support OF. Cc: Sherman Yin <syin@broadcom.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2014-01-16ARM: pinctrl: Add Broadcom Capri pinctrl driverSherman Yin
Adds pinctrl driver for Broadcom Capri (BCM281xx) SoCs. v4: - PINCTRL selected in Kconfig, PINCTRL_CAPRI selected in bcm_defconfig - make use of regmap - change CAPRI_PIN_UPDATE from macro to inline function. - Handle pull-up strength arg in Ohm instead of enum v3: Re-work driver to be based on generic pin config. Moved config selection from Kconfig to bcm_defconfig. v2: Use hyphens instead of underscore in DT property names.
