2015-03-27pinctrl: constify of_device_id arrayFabian Frederick1-1/+1
of_device_id is always used as const.

2014-10-20pinctrl: drop owner assignment from platform_driversWolfram Sang1-1/+0
A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2014-09-04pinctrl: clean up after enable refactoringLinus Walleij1-2/+2
commit 2243a87d90b42eb38bc281957df3e57c712b5e56 "pinctrl: avoid duplicated calling enable_pinmux_setting for a pin" removed the .disable callback from the struct pinmux_ops, making the .enable() callback the only remaining callback. However .enable() is a bad name as it seems to imply that a muxing can also be disabled. Rename the callback to .set_mux() and also take this opportunity to clean out any remaining mentions of .disable() from the documentation.

2014-04-22pinctrl: as3722: fix handling of GPIO invert bitAndrew Bresticker1-6/+11
The AS3722_GPIO_INV bit will always be blindly overwritten by as3722_pinctrl_gpio_set_direction() and will be ignored when setting the value of the GPIO in as3722_gpio_set() since the enable_gpio_invert flag is never set. This will cause an initially inverted GPIO to toggle when requested as an output, which could be problematic if, for example, the GPIO controls a critical regulator. Instead of setting up the enable_gpio_invert flag, just leave the invert bit alone and check it before setting the GPIO value.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull bulk pin control changes from Linus Walleij: "This has been queued and tested for a while. Lots of action here, like in the GPIO tree, embedded stuff like this is really hot now it seems. Details in the signed tag. I'm especially happy about the Qualcomm driver as it is used in such a huge subset of mobile handsets out there, and these platforms in general need better upstream support - New driver for the Qualcomm TLMM pin controller and its msm8x74 subdriver. - New driver for the Broadcom Capri BCM281xx SoC. - New subdriver for the imx25 pin controller. - New subdriver for the Tegra124 pin controller. - Lock GPIO lines as IRQs for select combined pin control and GPIO drivers for baytrail and sirf. - Some semi-big refactorings and extenstions to the sirf driver. - Lots of patching, cleanup and fixing in the Renesas "PFC" driver and associated subdrivers as usual. It is settling down a little bit now it seems. - Minor fixes and incremental updates here and there as usual" * tag 'pinctrl-v3.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (72 commits) pinctrl: sunxi: Honor GPIO output initial vaules pinctrl: capri: add dependency on OF ARM: bcm11351: Enable pinctrl for Broadcom Capri SoCs ARM: pinctrl: Add Broadcom Capri pinctrl driver pinctrl: Add pinctrl binding for Broadcom Capri SoCs pinctrl: Add void * to pinctrl_pin_desc pinctrl: st: Fix a typo in probe pinctrl: Fix some typos and grammar issues in the documentation pinctrl: sirf: lock IRQs when starting them pinctrl: sirf: put gpio interrupt pin into input status automatically pinctrl: sirf: use only one irq_domain for the whole device node pinctrl: single: fix infinite loop caused by bad mask pinctrl: single: fix pcs_disable with bits_per_mux pinctrl: single: fix DT bindings documentation pinctrl: as3722: Set pin to output mode for some function pinctrl: sirf: add pin group for USP0 with only RX or TX frame sync pinctrl: sirf: fix the pins of sdmmc5 connected with TriG pinctrl: sirf: add lost usp1_uart_nostreamctrl group for atlas6 pinctrl: sunxi: Add Allwinner A20 clock output pin functions pinctrl/lantiq: fix typo ...

2013-12-04gpio/pinctrl: make gpio_chip members typed booleanLinus Walleij1-1/+1
This switches the two members of struct gpio_chip that were defined as unsigned foo:1 to bool, because that is indeed what they are. Switch all users in the gpio and pinctrl subsystems to assign these values with true/false instead of 0/1. The users outside these subsystems will survive since true/false is 1/0, atleast we set some kind of more strict typing example. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-10-10pincntrl: add support for ams AS3722 pin control driverLaxman Dewangan1-0/+630
The AS3722 is a compact system PMU suitable for mobile phones, tablets etc. Add a driver to support accessing the GPIO, pinmux and pin configuration of 8 GPIO pins found on the ams AS3722 through pin control driver and gpiolib. The driver will register itself as the pincontrol driver and gpio driver. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
