      drivers/pinctrl: grab default handles from device core · ab78029e
      Linus Walleij authored
      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.
