* pinctrl: header: trivial: declare struct deviceRichard Genoud2012-08-171-0/+1
| | | | | | | | As struct device is used as a function argument, it should at least be declared (device.h is not included). Signed-off-by: Richard Genoud <richard.genoud@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* pinctrl: implement devm_pinctrl_get()/put()Stephen Warren2012-04-181-0/+44
| | | | | | | | These functions allow the driver core to automatically clean up any allocations made by drivers, thus leading to simplified drivers. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* pinctrl: split pincontrol states into its own headerLinus Walleij2012-03-061-1/+1
| | | | | | | | | | | Move the pin control state defines into its own header file, since it is used both by machine.h which is facing the platform and by consumer.h which is facing the drivers, and pinctrl.h which is pinctrl-driver internal, let's not have each and every .h file include all others, then isolation is moot.

* pinctrl: API changes to support multiple states per deviceStephen Warren2012-03-051-7/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The API model is changed from: p = pinctrl_get(dev, "state1"); pinctrl_enable(p); ... pinctrl_disable(p); pinctrl_put(p); p = pinctrl_get(dev, "state2"); pinctrl_enable(p); ... pinctrl_disable(p); pinctrl_put(p); to this: p = pinctrl_get(dev); s1 = pinctrl_lookup_state(p, "state1"); s2 = pinctrl_lookup_state(p, "state2"); pinctrl_select_state(p, s1); ... pinctrl_select_state(p, s2); ... pinctrl_put(p); This allows devices to directly transition between states without disabling the pin controller programming and put()/get()ing the configuration data each time. This model will also better suit pinconf programming, which doesn't have a concept of "disable". The special-case hogging feature of pin controllers is re-written to use the regular APIs instead of special-case code. Hence, the pinmux-hogs debugfs file is removed; see the top-level pinctrl-handles files for equivalent data.

* pinctrl: factor pin control handles over to the coreLinus Walleij2012-02-101-4/+4
| | | | | | | | | | | | This moves the per-devices struct pinctrl handles and device map over from the pinmux part of the subsystem to the core pinctrl part. This makes the device handles core infrastructure with the goal of using these handles also for pin configuration, so that device drivers (or boards etc) will need one and only one handle to the pin control core.

* pinctrl: move generic functions to the pinctrl_ namespaceLinus Walleij2012-02-101-17/+17
| | | | | | | | | | | | | | Since we want to use the former pinmux handles and mapping tables for generic control involving both muxing and configuration we begin refactoring by renaming them from pinmux_* to pinctrl_*. ChangeLog v1->v2: - Also rename the PINMUX_* macros in machine.h to PIN_ as indicated in the documentation so as to reflect the generic nature of these mapping entries from now on.

* pinctrl: break out a pinctrl consumer headerLinus Walleij2012-02-101-0/+118
This breaks out a <linux/pinctrl/consumer.h> header to be used by all pinmux and pinconfig alike, so drivers needing services from pinctrl does not need to include different headers. This is similar to the approach taken by the regulator API. Acked-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
