  • 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.

  • 57ef04288   gpio: switch drivers to use new callback ... Browse Code »

    This switches all GPIO and pin control drivers with irqchips
    that were using .startup() and .shutdown() callbacks to lock
    GPIO lines for IRQ usage over to using the .request_resources()
    and .release_resources() callbacks just introduced into the
    irqchip vtable.

  • f41cd3c28   gpio: lock adnp IRQs when enabling them ... Browse Code »

    This uses the new API for tagging GPIO lines as in use by
    IRQs. This enforces a few semantic checks on how the underlying
    GPIO line is used.

    Only compile tested on the lpc32xx.

    ChangeLog v2->v3:
    - Switch to using the startup()/shutdown() callbacks again.
    Still satisfy the mask/unmask semantics.
    ChangeLog v1->v2:
    - Use the .enable() callback from the irq_chip
    - Call .unmask() from the .enable() callback to satisfy semantics.

  • 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.

  • 5b21533b7   gpio: adnp: Fix segfault if request_threaded_irq fails ... Browse Code »

    In case request_threaded_irq inside adnp_irq_setup fails, the driver
    segfaults. This is because irq_domain_remove is called twice with
    the same pointer. First time in adnp_irq_setup and then a second time
    after leaving adnp_irq_setup in the error path of adnp_i2c_probe
    inside adnp_teardown.
    This fixes this by removing the call to irq_domain_remove from
    adnp_irq_setup.

  • 5e969a401   gpio: Add Avionic Design N-bit GPIO expander support ... Browse Code »

    This commit adds a driver for the Avionic Design N-bit GPIO expander.
    The expander provides a variable number of GPIO pins with interrupt
    support.

    Changes in v2:
    - allow building the driver as a module
    - assign of_node unconditionally
    - use linear mapping IRQ domain
    - properly cleanup IRQ domain
    - add OF device table and annotate device tables
    - emulate rising and falling edge triggers
    - increase #gpio-cells to 2
    - drop support for !OF
    - use IS_ENABLED to conditionalize DEBUG_FS code

    Changes in v3:
    - make IRQ support runtime configurable (interrupt-controller property)
    - drop interrupt-controller and #interrupt-cells from DT binding
    - add inline to_adnp() function to wrap container_of() macro
    - consistently use adnp as name for struct adnp variables
    - remove irq_mask_cur and rename irq_mask to irq_enable
    - fix a subtle deadlock in adnp_gpio_direction_output()
    - remove dynamic allocations from debugfs code
    - rename regs to num_regs to avoid confusion
    - annotate non-trivial code with comments
    - don't acquire mutex in adnp_gpio_get()
    - assume NO_IRQ == 0
