  • e35b5ab0a   gpio: constify gpio_chip structures ... Browse Code »

    These structures are only used to copy into other structures, so declare
    them as const.

    The semantic patch that makes this change is as follows:
    (http://coccinelle.lip6.fr/)

    //
    @r disable optional_qualifier@
    identifier i;
    position p;
    @@
    static struct gpio_chip i@p = { ... };

    @ok@
    identifier r.i;
    expression e;
    position p;
    @@
    e = i@p;

    @bad@
    position p != {r.p,ok.p};
    identifier r.i;
    struct gpio_chip e;
    @@
    e@i@p

    @depends on !bad disable optional_qualifier@
    identifier r.i;

    static
    +const
    struct gpio_chip i = { ... };

  • 190ea4344   gpio: wm8994: use the new open drain callback ... Browse Code »

    The WM8994 GPIOs clearly have a dedicated open drain control
    register. Implement support for controlling this from GPIO
    descriptor tables or other hardware descriptions such as
    device tree by implementing the .set_single_ended() callback.

    Before this patch, lines requesting open drain will just be
    switched to input mode by the framework, thus emulating open
    drain. But the hardware can do the real thing, so let's
    support that.

    As part of this, rename the debugfs string for output mode
    from "CMOS" to "push-pull" because it is the term used in
    the framework to signify a tomem-pole CMOS output.

  • 765aa5877   gpio: wm8994: use gpiochip data pointer ... Browse Code »

    This makes the driver use the data pointer added to the gpio_chip
    to store a pointer to the state container instead of relying on
    container_of().

  • 58383c784   gpio: change member .dev to .parent ... Browse Code »

    The name .dev in a struct is normally reserved for a struct device
    that is let us say a superclass to the thing described by the struct.
    struct gpio_chip stands out by confusingly using a struct device *dev
    to point to the parent device (such as a platform_device) that
    represents the hardware. As we want to give gpio_chip:s real devices,
    this is not working. We need to rename this member to parent.

    This was done by two coccinelle scripts, I guess it is possible to
    combine them into one, but I don't know such stuff. They look like
    this:

    @@
    struct gpio_chip *var;
    @@
    -var->dev
    +var->parent

    and:

    @@
    struct gpio_chip var;
    @@
    -var.dev
    +var.parent

    and:

    @@
    struct bgpio_chip *var;
    @@
    -var->gc.dev
    +var->gc.parent

    Plus a few instances of bgpio that I couldn't figure out how
    to teach Coccinelle to rewrite.

    This patch hits all over the place, but I *strongly* prefer this
    solution to any piecemal approaches that just exercise patch
    mechanics all over the place. It mainly hits drivers/gpio and
    drivers/pinctrl which is my own backyard anyway.

  • 9fb1f39eb   gpio/pinctrl: make gpio_chip members typed boolean ... Browse Code »

    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.

  • f948ad078   Merge tag 'gpio-for-v3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio ... Browse Code »

    Pull GPIO changes from Linus Walleij:
    - New driver for AMD-8111 southbridge GPIOs
    - New driver for Wolfson Micro Arizona devices
    - Propagate device tree parse errors
    - Probe deferral finalizations - all expected calls to GPIO will now
    hopefully request deferral where apropriate
    - Misc updates to TCA6424, WM8994, LPC32xx, PCF857x, Samsung MXC, OMAP
    and PCA953X drivers.

    Fix up gpio_idx conflicts in drivers/gpio/gpio-mxc.c
