Let's stop spawning the pinctrl driver from the GPIO driver, we have these two mechanisms broken apart now, and they can each probe in isolation. If the GPIO driver cannot find its pin controller (pinctrl-u300), the pin controller core will tell it to defer probing.

This switches the COH 901 pinctrl driver to allocate its GPIO IRQs dynamically, and start to use a linear irqdomain to map from the hardware IRQs. This way we can cut away the complex allocation of IRQ numbers from the <mach/irqs.h> file. Signed-off-by: NLinus Walleij <linus.walleij@linaro.org>

The U300 IRQs were bumped once to offset to 1 (in order to avoid using IRQ 0 which is now NO_IRQ). This was OK as we were still passing the number of irqs in the .nr_irqs field of the machine, with descriptors allocated at boot time. However .nr_irqs should be 0, leading the system to reserve the first 16 IRQs. Then the VIC driver will complain that IRQs 1 thru 15 are pre-allocated, so to avoid this and use free descriptors, move all IRQs up to offset 32. This will all be done away with as we migrate to device tree, so it is an interim solution. Acked-by: NOlof Johansson <olof@lixom.net> Signed-off-by: NLinus Walleij <linus.walleij@linaro.org>

Amend the PL022 pin controller to optionally take a pin control handle and set the state of the pins to "default" on boot and runtime resume, and to "sleep" at runtime suspend. This way we will dynamically save power on the SPI busses, for example some electronic designs may be able to ground the pins when unused instead of pull-up. Some pin controllers may want to set the pins as wake-up sources when sleeping. Effect on platforms using the PL022 driver: - If the platform does not use pin control - no semantic effect, the pinctrl stubs will kick in and resolve the situation. - Platforms using this driver and have pin control but no function defined for the PL022 need to either supply a "default" function in their map or enable pinctrl dummies so the driver is satisfied. - Platforms using this driver with hogs for setting up the PL022 pin control - stop using hogs to take the pl022 pin control handle, let the driver handle this. I'be looked at some platforms that may be affected: - SPEAr: appears to define the proper functions in their device trees and not hogging them, so things should be smooth, the driver will simply start to take its pins. - Ux500: the proper function is defined and will be taken properly by the driver. New sleep states introduced by a separate patch to ux500 but no regression, since the default state is sufficient. - U300: old hog deleted as part of this patch. - LPC32xx: does not appear to be using pinctrl. - ARM Integrator IMPD1, RealView & Versatile: does not use pinctrl.

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_register_mappings() already requires that every mapping table entry have a non-NULL name field. Logically, this makes sense too; drivers should always request a specific named state so they know what they're getting. Relying on getting the first mentioned state in the mapping table is error-prone, and a nasty special case to implement, given that a given the mapping table may define multiple states for a device. Remove a small part of the documentation that talked about optionally requesting a specific state; it's mandatory now.

This provides a single centralized name for the default state. Update PIN_MAP_* macros to use this state name, instead of requiring the user to pass a state name in. With this change, hog entries in the mapping table are defined as those with state name PINCTRL_STATE_DEFAULT, i.e. all entries have the same name. This interacts badly with the nested iteration over mapping table entries in pinctrl_hog_maps() and pinctrl_hog_map() which would now attempt to claim each hog mapping table entry multiple times. Replacing the custom hog code with a simple pinctrl_get()/pinctrl_enable(). Update documentation and mapping tables to use this.

This makes a deep copy of the pinmux function map instead of keeping the copy supplied from the platform around. This makes it possible to tag the platforms map with __initdata as is also done as part of this patch. Rationale: a certain target platform (PXA) has numerous pinmux maps, many of which will be lying around unused after boot in a multi-platform binary. Instead, deep-copy the one we're going to use and tag them all __initdata so they go away after boot. ChangeLog v1->v2: - Fixup the deep copy, missed a few items on the struct, plus mark bool member non-const since we're making runtime copies if this stuff now. ChangeLog v2->v3: - Make a shallow copy (just copy the array of map structs) as Arnd noticed, string constants never get discarded by the kernel anyway, so these pointers may be safely copied over.

This adds a driver for the U300 pinmux portions of the system controller "SYSCON". It also serves as an example of how to use the pinmux subsystem. This driver also houses the platform data for the only supported platform. This deletes the old U300 driver in arch/arm/mach-u300 and replace it with a driver using the new subsystem. The new driver is considerably fatter than the old one, but it also registers all 467 pins of the system and adds the power and EMIF pin groups and corresponding functions. The idea is to use this driver as a a reference for other implementation so it needs to be as complete and verbose as possible.
