  • 8a06b08ec   gpio: ich: Use devm_request_region ... Browse Code »

    By the time request_region is called in the Intel ICH series GPIO
    driver, a corresponding device structure has already been allocated. The
    devm_request_region function should be used to help simplify the cleanup
    code and reduce the possible points of failure.

  • 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.

  • e97f9b527   gpio/gpio-ich: fix ichx_gpio_check_available() return what callers expect ... Browse Code »

    ichx_gpio_check_available() returns either 0 or -ENXIO depending on whether
    the given GPIO is available or not. However, callers of this function treat
    the return value as boolean:

    ...
    if (!ichx_gpio_check_available(gpio, nr))
    return -ENXIO;

    which erroneusly fails when the GPIO is available and not vice versa.

    Fix this by making the function return boolean as expected by the callers.

  • 4f600ada7   gpio: gpio-ich: Share ownership of GPIO groups ... Browse Code »

    The ICH chips have their GPIO pins organized in 2 or 3 independent
    groups of 32 GPIO pins. It can happen that the ACPI BIOS wants to make
    use of pins in one group, preventing the OS to access these. This does
    not prevent the OS from accessing the other group(s).

    This is the case for example on my Asus Z8NA-D6 board. The ACPI BIOS
    wants to control GPIO 18 (group 1), while I (the OS) need to control
    GPIO 52 and 53 (group 2) for SMBus multiplexing.

    So instead of checking for ACPI resource conflict on the whole I/O
    range, check on a per-group basis, and consider it a success if at
    least one of the groups is available for the OS to use.

  • 6ed9f9c40   gpio: Add support for Intel ICHx/3100/Series[56] GPIO ... Browse Code »

    This driver works on many Intel chipsets, including the ICH6, ICH7,
    ICH8, ICH9, ICH10, 3100, Series 5/3400 (Ibex Peak), Series 6/C200
    (Cougar Point), and NM10 (Tiger Point).

    Additional Intel chipsets should be easily supported if needed, eg the
    ICH1-5, EP80579, etc.

    Tested on QM67 (Cougar Point), QM57 (Ibex Peak), 3100 (Whitmore Lake),
    and NM10 (Tiger Point).

    Includes work from Jean Delvare:
    - Resource leak removal during module load/unload
    - GPIO API bit value enforcement

    Also includes code cleanup from Guenter Roeck and Grant Likely.
