Subject: [PATCH v2 0/8] ARM: sun8i: a83t: Enable AXP813/AXP818 regulators

Hi everyone,

This series was originally name "regulator: axp20x: Add support for
AXP813/818 regulators". It adds support for the X-Powers AXP813/818 [1]
PMICs' regulators. The series is quite straightforward.

Changes since v1:

  - Regulator driver patches were merged and now dropped from the series

  - Chose simpler names for the regulators

  - Added SDIO WiFi enablement patches

Patch 1 adds a axp20x-regulator cell for AXP813, thereby enabling the
regulators.

Patch 2 adds a shared dtsi file for the PMIC. This currently contains
a list of regulator nodes, but will be expanded with Quentin's power
supply work.

Patches 3 through 5 add regulator nodes to board dts files for the A83T
boards that I have. They are not squashed together as each file has
substantial additions.

Patch 6 moves the mmc1 pinmux setting over to the dtsi, and sets it by
default.

Patches 7 & 8 enable SDIO-based WiFi on the Cubietruck Plus and Banana
Pi M3.

Originally my work also included enabling Ethernet. But the Ethernet
bindings were reverted. Everything can be found here:

    https://github.com/wens/linux/tree/a83t-regulator-wifi-eth

Please have a look.

Lee, we need the mfd changes merged in before merging the dts changes.
Otherwise, mmc would break as vmmc/vqmmc is tied to the PMIC regulators.

Regards
ChenYu

[1] AXP813 and AXP818 are functionally identical. They have different
    labels and are bundled with different SoCs (A83T and H8), as a sort
    of product or market segmentation.
