    Subject[PATCH v3 0/7] Add support for pinctrl/gpio on Armada 37xx
    Date
    Hi,

    In this third version I finally managed to use gpio-ranges from the
    device tree. For the record, this series adds support for the pin and
    gpio controllers present on the Armada 37xx SoCs.

    Each Armada 37xx SoC comes with 2 pin controllers: one on the south
    bridge (managing 28 pins) and one on the north bridge (managing 36 pins).

    At the hardware level the controller configure the pins by group and not
    pin by pin.

    The gpio controller is also capable to handle interrupt from gpio.

    Changelog

    v2 -> v3
    - use gpio-ranges (patch 4)

    - Document gpio-ranges usage (patch 1)

    - do not use anymore a global pin index (patch 3)

    v1 -> v2:
    - Update binding documentation making clear that mfd and syscon must
    be used (patch 1).

    - Split the fist patch adding pin controller support for Armada 37xx
    in arm64 part (for kconfig) and pinctrl part (patch 2 and 3)

    - Add MFD_SYSCON dependency (patch 3)

    - Add kerneldoc for the armada_37xx_pin_group struct (patch 3)

    - Rename _add_function() to armada_37xx_add_function() (patch 3)

    - Use an inline function to update the reg offset (patch 4)

    - Rename gpiolib_register to gpiochip_register (patch 4)

    - Add a comment about the two registers limit (patch 4)

    - Add explicit gpio node in the device tree (patch 4)

    - Convert the driver to use GPIOLIB_IRQCHIP (patch 5)

    - Add a critical section when accessing the hardware registers (patch 5)

    - Use the gpio subnode (patch 5)

    Thanks,

    Gregory
