2012-07-14pinctrl: pinctrl-imx6q: add missed mux function for USBOTG_IDDong Aisheng1-0/+2
The original pin registers table is derived from u-boot mainline, but somehow it was found missing some mux functions for USBOTG_ID. We added it at the bottom by following the exist pin function ids, then it will not break the exist using of pin function id in dts file.

Commit a60b57eddaa8af6c02cf7bbeb58ebf82881f08ac "drivers/gpio: gpio-nomadik: Add support for irqdomains" changed GPIO offset calculations to have this form: (gpio % NMK_GPIO_PER_CHIP) except in this one place for setting sleep mode, where the conversion was all wrong, and instead mod:ing the GPIO with the IRQ base which does not make any sense.

2012-05-11pinctrl/nomadik: implement pin configurationLinus Walleij2-0/+114
This implements the pin configuration interface for the Nomadik pin controller. As part of the exercise we add a bit in the pin_cfg_t for the Nomadik pinctrl driver that indicates if the pin should be forced into GPIO mode. This is not done to go behind the back of the GPIO subsystem, but to ensure that default modes can be set by hogs on boot and system suspend/resume states. It was used implicitly by the old code defining all config settings and modes in a single config word but we now have a split between pinmux and pinconf leading to the need to have this. We also add a bit for explicitly setting sleepmode of the pin. This was previously handled by custom calls with the _sleep() suffix, but we now have one single interface into the configuration so we replace this with a bit indicating that the pin shall be configured into sleep mode. Some of the configuration can be refactored later to use less custom fields on the pin_cfg_t but we are currently leaving the old function calls in place so we stay compatible. ChangeLog v1->v2: - Drop a hunk changing pinmuxing for GPIO and move it over to the preceding pinmux patch.

2012-05-11pinctrl/nomadik: implement pin multiplexingLinus Walleij4-2/+353
Implements basic pinmux for the Nomadik pin controller. The plan is to split the existing singular pin config interface nmk_config_pin(), nmk_config_pins(), that will configure muxing and other settings at the same time, into two interfaces by splitting the code in pinmux and pinctrl and eventually deleting the old interface and its helper functions when all users are gone. nmk_gpio_set_mode() and nmk_gpio_get_mode() are two older interfaces for just configuring muxing/altfunctions that will also be replaced in the end. We take some extra care to handle the glitch-avoidance here, but it is simpler now since there is only one altsetting per pingroup so we know immediately if we need to avoid altfunc C glitches for a certain group. As part of the makeover implement the .request() and .free() calls on the GPIO chips and have them call back into the pinctrl layer to reserve GPIOs. ChangeLog v1->v2: - Rebased on pinctrl-mergebase-20120418 so we get the latest driver infrastructure where function count is done by a fixed value and we can drop a few range checks since this is now handled by the core. - Include a GPIO muxing hunk erroneously part of the pin config patch.

2012-05-07pinctrl: add more info to error msgs in pin_requestStephen Warren1-6/+8
Additionally print which pin the request failed for, which entity already claimed it, and what entity was trying to claim it. Remove duplicate device name from a debug message.

2012-05-02pinctrl: add pinctrl-mxs supportShawn Guo6-0/+1343
Add pinctrl support for Freescale MXS SoCs, i.MX23 and i.MX28. The driver supports device tree probe only. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Stephen Warren <swarren@wwwdotorg.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2012-05-02pinctrl: pinctrl-imx: add imx pinctrl core driverDong Aisheng4-0/+739
The driver has mux and config support while the gpio is still not supported. For select input setting, the driver will handle it internally and do not need user to take care of it. The pinctrl-imx core driver will parse the dts file and dynamically create the pinmux functions and groups. Each IMX SoC pinctrl driver should register pins with a pin register map including mux register and config register and select input map to core for proper operations.

2012-05-02pinctrl: support gpio request deferred probingDong Aisheng1-3/+4
As pinctrl handles, it may be possible the pinctrl gpio ranges are still not got registered when user call pinctrl_gpio_request. Thus, add defer support for it too.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson into next/gpio Linus Walleij <linus.walleij@linaro.org> writes: This is a pull request for the GPIO and pin control stuff accumulated in the ST-Ericsson tree. Here we have: - Improvements and fixes and a custom pin config API from Rabin Vincent - Device Tree bindings from Lee Jones - Some accumulated patches by yours truly. - A MSP platform data init patch from Ola Lilja that is merged here due to dependency on pin config work. It is to be used with work being worked on in parallel in the ALSA SoC subsystem. If you wonder about the custom pin config implementation this is to be used as a transition base as I am rewriting the driver to use pinctrl. Expect a final pull request on top of this one that will move the ux500 over to pinctrl. * 'ux500-gpio-pins-for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson: ARM: ux500: Add support for MSP I2S-devices drivers/gpio: gpio-nomadik: Add support for irqdomains drivers/gpio: gpio-nomadik: Apply Device Tree bindings ARM: ux500: update pin handling ARM: ux500: implement pin API ARM: ux500: remove a bunch of internal pull-ups plat-nomadik: new sleep mode pincfg macros gpio/nomadik: use ioremap() instead of static mappings gpio/nomadik: support low EMI mode gpio/nomadik: fix spurious interrupts with SKE gpio/nomadik: cache [rf]w?imsc gpio/nomadik: don't set SLPM to 1 for non-wakeup pins Also includes an update to v3.4-rc4.

2012-04-26pinctrl: add pinctrl_provide_dummies interface for platforms to useDong Aisheng1-2/+27
Add a interface pinctrl_provide_dummies for platform to indicate whether it needs use pinctrl dummy state. ChangeLog v3->v4: * remove dummy gpio support in pinctrl subsystem. Let gpio driver decide whether it wants to use pinctrl gpio mux function. ChangeLog v2->v3: * Also changed the missed pinctrl gpio APIs in v1. ChangeLog v1->v2: * Based on sascha's suggestion, drop using kconfig since it will hide pinctrl errors on all other boards. See: https://lkml.org/lkml/2012/4/18/282 It seemed both Linus and Stephen agreed with this way, so i'm ok with it too. * Add dummy gpio support. pinctrl gpio in the same situation as state. * Patch name changed. Original is pinctrl: handle dummy state in core. * Split removing old dt dummy interface into a separate patch Cc: Linus Walleij <linus.walleij@linaro.org> Cc: Sascha Hauer <s.hauer@pengutronix.de> Acked-by: Stephen Warren <swarren@wwwdotorg.org> Signed-off-by: Dong Aisheng <dong.aisheng@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
