  • e42615ec2   gpio: Use new GPIO_LINE_DIRECTION ... Browse Code »

    It's hard for occasional GPIO code reader/writer to know if values 0/1
    equal to IN or OUT. Use defined GPIO_LINE_DIRECTION_IN and
    GPIO_LINE_DIRECTION_OUT to help them out.

    NOTE - for gpio-amd-fch and gpio-bd9571mwv:
    This commit also changes the return value for direction get to equal 1
    for direction INPUT. Prior this commit these drivers might have
    returned some other positive value but 1 for INPUT.

  • 0e3cb6ee3   gpio: gpio-reg: add irq mapping for gpio-reg users ... Browse Code »

    Add support for mapping gpio-reg gpios to interrupts. This may be a
    non-linear mapping - some gpios in the register may not even have
    corresponding interrupts associated with them, so we need to pass an
    array.

  • 380639c7c   gpio: add generic single-register fixed-direction GPIO driver ... Browse Code »

    Add a simple, generic, single register fixed-direction GPIO driver.
    This is able to support a single register with a mixture of inputs
    and outputs.

    This is different from gpio-mmio and gpio-74xx-mmio:
    * gpio-mmio doesn't allow a fixed direction, it assumes there is always
    a direction register.
    * gpio-74xx-mmio only supports all-in or all-out setups
    * gpio-74xx-mmio is DT only, this needs to support legacy too
    * they don't double-read when getting the GPIO value, as required by
    some implementations that this driver supports
    * we need to always do 32-bit reads, which bgpio doesn't guarantee
    * the current output state may not be readable from the hardware
    register - reading may reflect input status but not output status.
