This moves the instances of the Nomadik pin controller and the Nomadik GPIO blocks (also handled by the GPIO driver) over to the device tree. A new compatible string is added to the pin control driver in the process. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2013-01-23drivers/pinctrl: grab default handles from device coreLinus Walleij
This makes the device core auto-grab the pinctrl handle and set the "default" (PINCTRL_STATE_DEFAULT) state for every device that is present in the device model right before probe. This will account for the lion's share of embedded silicon devcies. A modification of the semantics for pinctrl_get() is also done: previously if the pinctrl handle for a certain device was already taken, the pinctrl core would return an error. Now, since the core may have already default-grabbed the handle and set its state to "default", if the handle was already taken, this will be disregarded and the located, previously instanitated handle will be returned to the caller. This way all code in drivers explicitly requesting their pinctrl handlers will still be functional, and drivers that want to explicitly retrieve and switch their handles can still do that. But if the desired functionality is just boilerplate of this type in the probe() function: struct pinctrl *p; p = devm_pinctrl_get_select_default(&dev); if (IS_ERR(p)) { if (PTR_ERR(p) == -EPROBE_DEFER) return -EPROBE_DEFER; dev_warn(&dev, "no pinctrl handle\n"); } The discussion began with the addition of such boilerplate to the omap4 keypad driver: http://marc.info/?l=linux-input&m=135091157719300&w=2 A previous approach using notifiers was discussed: http://marc.info/?l=linux-kernel&m=135263661110528&w=2 This failed because it could not handle deferred probes. This patch alone does not solve the entire dilemma faced: whether code should be distributed into the drivers or if it should be centralized to e.g. a PM domain. But it solves the immediate issue of the addition of boilerplate to a lot of drivers that just want to grab the default state. As mentioned, they can later explicitly retrieve the handle and set different states, and this could as well be done by e.g. PM domains as it is only related to a certain struct device * pointer. ChangeLog v4->v5 (Stephen): - Simplified the devicecore grab code. - Deleted a piece of documentation recommending that pins be mapped to a device rather than hogged. ChangeLog v3->v4 (Linus): - Drop overzealous NULL checks. - Move kref initialization to pinctrl_create(). - Seeking Tested-by from Stephen Warren so we do not disturb the Tegra platform. - Seeking ACK on this from Greg (and others who like it) so I can merge it through the pinctrl subsystem. ChangeLog v2->v3 (Linus): - Abstain from using IS_ERR_OR_NULL() in the driver core, Russell recently sent a patch to remove it. Handle the NULL case explicitly even though it's a bogus case. - Make sure we handle probe deferral correctly in the device core file. devm_kfree() the container on error so we don't waste memory for devices without pinctrl handles. - Introduce reference counting into the pinctrl core using <linux/kref.h> so that we don't release pinctrl handles that have been obtained for two or more places. ChangeLog v1->v2 (Linus): - Only store a pointer in the device struct, and only allocate this if it's really used by the device.

It's not easy to handle multiple gpios sharing one pin register. So this gpio range feature will be implemented by other patches.

2013-01-18pinctrl: nomadik: Allow prcm_base to be extracted from Device TreeLee Jones
The Nomadik Pinctrl driver requires access to some PRCMU registers in order to run with full functionality. When Device Tree is disabled the required PRCMU base address is passed in via platform data, so in order for Device Tree booting to be as functional, we need a similar mechanism to fetch it from Device Tree. The new semantics goes like this: Parse the Device Tree and look for the PRCMU node using a provided Phandle. Obtain the ioremaped address from that node. If one was supplied via platform data over-write it with anything found in Device Tree. Fail if either the prcm_base can't be found if we're running on anything other than an STN8815 ASIC.

2013-01-11pinctrl: skip deferral of hogsLinus Walleij
Up until now, as hogs were always taken at the end of the pin control device registration, it didn't cause any problem. But when starting to hog pins from the device core it will cause deferral of the pin controller device itself since the default pin fetch is done *before* the device probes, so let's fix this annoyance (which is also aesthetically ugly). Also take some care to make sure that if any one map entry results in a deferral rather than a failure, then that deferral will take precedence.

2013-01-03Drivers: pinctrl: remove __dev* attributes.Greg Kroah-Hartman
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-12-26pinctrl: nomadik: return if prcm_base is NULLFabio Baltieri
This patch adds a check for npct->prcm_base to make sure that the address is not NULL before using it, as the driver was made capable of loading even without a proper memory resource in: f1671bf pinctrl/nomadik: make independent of prcmu driver Also, refuses to probe without prcm_base on anything else than nomadik. This solves the following crash, introduced during the merge window when booting on U8500 with device tree: pinctrl-nomadik pinctrl-db8500: No PRCM base, assume no ALT-Cx control is available Unable to handle kernel NULL pointer dereference at virtual address 00000138 pgd = c0004000 [00000138] *pgd=00000000 Internal error: Oops: 5 [#1] PREEMPT SMP ARM Modules linked in: CPU: 0 Not tainted (3.7.0-02892-g1ebaf4f #631) PC is at nmk_pmx_enable+0x1bc/0x4d0 LR is at clk_disable+0x40/0x44 [snip] [<c01d5e50>] (nmk_pmx_enable+0x1bc/0x4d0) from [<c01d3ba8>] (pinmux_enable_setting+0x12c/0x1ec) [<c01d3ba8>] (pinmux_enable_setting+0x12c/0x1ec) from [<c01d1dc8>] (pinctrl_select_state_locked+0xfc/0x134) [<c01d1dc8>] (pinctrl_select_state_locked+0xfc/0x134) from [<c01d2814>] (pinctrl_register+0x26c/0x43c) [<c01d2814>] (pinctrl_register+0x26c/0x43c) from [<c01d668c>] (nmk_pinctrl_probe+0x114/0x238) [<c01d668c>] (nmk_pinctrl_probe+0x114/0x238) from [<c0211cc4>] (platform_drv_probe+0x28/0x2c) [<c0211cc4>] (platform_drv_probe+0x28/0x2c) from [<c0210738>] (driver_probe_device+0x84/0x21c) [<c0210738>] (driver_probe_device+0x84/0x21c) from [<c02109c0>] (__device_attach+0x50/0x54) [<c02109c0>] (__device_attach+0x50/0x54) from [<c020eb1c>] (bus_for_each_drv+0x54/0x9c) [<c020eb1c>] (bus_for_each_drv+0x54/0x9c) from [<c0210668>] (device_attach+0x84/0x9c) [<c0210668>] (device_attach+0x84/0x9c) from [<c020fbac>] (bus_probe_device+0x94/0xb8) [<c020fbac>] (bus_probe_device+0x94/0xb8) from [<c020e084>] (device_add+0x4f0/0x5bc) [<c020e084>] (device_add+0x4f0/0x5bc) from [<c0276400>] (of_device_add+0x40/0x48) [<c0276400>] (of_device_add+0x40/0x48) from [<c0276a98>] (of_platform_device_create_pdata+0x68/0x98) [<c0276a98>] (of_platform_device_create_pdata+0x68/0x98) from [<c0276bac>] (of_platform_bus_create+0xe4/0x260) [<c0276bac>] (of_platform_bus_create+0xe4/0x260) from [<c0276bf8>] (of_platform_bus_create+0x130/0x260) [<c0276bf8>] (of_platform_bus_create+0x130/0x260) from [<c0276d94>] (of_platform_populate+0x6c/0xac) [<c0276d94>] (of_platform_populate+0x6c/0xac) from [<c04a8224>] (u8500_init_machine+0x78/0x140) [<c04a8224>] (u8500_init_machine+0x78/0x140) from [<c04a3560>] (customize_machine+0x24/0x30) [<c04a3560>] (customize_machine+0x24/0x30) from [<c00087b0>] (do_one_initcall+0x130/0x1b0) [<c00087b0>] (do_one_initcall+0x130/0x1b0) from [<c033ff9c>] (kernel_init+0x138/0x2e8) [<c033ff9c>] (kernel_init+0x138/0x2e8) from [<c000eb18>] (ret_from_fork+0x14/0x20) Code: 0a00001b e19400b2 e59a200c e0822000 (e592c000) ---[ end trace 1b75b31a2719ed1c ]--- note: swapper/0[1] exited with preempt_count 1 Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b Signed-off-by: Fabio Baltieri <fabio.baltieri@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
