[PATCH v2 0/7] ARM: berlin: add pinctrl support

[Antoine Ténart]

This series adds support for the Marvell Berlin pin-controller, allowing
to configure the pin muxing from the device tree.

The Berlin pin-controller support is divided into 3 drivers, each
driving one Berlin SoC. These drivers use a Berlin common part.

This series applies on top of patches introducing the Marvell Berlin
BG2Q you can find on Sebastian's berlin/for-next branch[1] and the patch
allowing not to define the get_group_pins() function[2].

Tested on the Berlin BG2Q.

[2] https://patchwork.kernel.org/patch/3964491/

Changes since v1:
        - moved the driver to a specific berlin/ directory
        - divided the pin-controller driver into three (one per SoC) and
          reworked the driver dependencies accordingly
        - reworked the device tree bindings
        - removed the reg-names and reworked the driver to allow
          splitting the two pin-controllers into two separate nodes in
          the device tree
        - updated the documentation
        - removed unnecessary checks
        - added support to mux multiple groups with the same function
        - added BG2, BG2 and BG2CD function definitions
