Hi,

Obviously this cover letter is wrong. Actually I forgot to commit it in
git series. Here it is the correct one:

After several months here it is the second version of the series adding
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.

In the second version several changes has been done:

- 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 sub-node (patch 5)

With these change most of the comment of the first revision have been addressed.

Thanks,

Gregory
