[PATCH v5 00/10] AXP803 PMIC support for Pine64

[Icenowy Zheng]

The Pine64 (including Pine64+) boards have an AXP803 PMIC, which is a PMIC
similar to AXP288, but tweaked to use with Allwinner SoCs rather than Intel
tablets (with DCIN and Vbus re-splitted like other AXP PMICs, and RSB bus
support added).

This patchset adds support for it and enabled it in Pine64 device tree.

The basical part of AXP803 MFD driver is already applied, according to Lee.

Thus this patchset is now still two parts, but a bit different to older
revisions:

- Part1: from PATCH 1/10 to PATCH 5/10, which focus on enabling AXP803 in
  the device tree: the RSB bus, the R_INTC interrupt controller (for the
  NMI line, which is connected to AXP803 on Pine64), and finally the basical
  AXP803 node.
- Part2: from PATCH 5/10 to PATCH 10/10, which are enabling the regulator
  function of the AXP803 PMIC. Finally Wi-Fi function is added
  as a usage of regulators function.

PATCH 1 adds RSB device nodes, which is used for the communication between
A64 and AXP803.

PATCH 2 adds device tree binding of A64 R_INTC.

PATCH 3 really adds support for A64 R_INTC in NMI driver.

PATCH 4 adds R_INTC node in A64 device tree.

PATCH 5 adds AXP803 node to the Pine64 device tree by using already
applied drivers/bindings.

PATCH 6 adds support for AXP803 regulators in AXP20x regulatoe driver.
(The binding is already applied)

PATCH 7 enables the AXP803 regulator cell in MFD driver.

PATCH 8 adds a DTSI file for AXP803, like other older AXP PMICs.

PATCH 9 enables AXP803 regulators in Pine64 device tree.

PATCH 10 enables Wi-Fi for Pine64.
