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
This patchset adds support for it and enabled it in Pine64 device tree.
This patchset can be splitted into two big parts:
- Part1: PATCH 1/11 to PATCH 5/11, which are enabling the MFD (and the
power key functionality) of AXP803.
- Part2: PATCH 6/11 to PATCH 11/11, which are enabling the regulator
function of the AXP803 PMIC. Finally Wi-Fi function is added
as a usage of regulators function.
PATCH 1 and 2 added RSB and NMI device nodes, which are used for the
communication between A64 and AXP803.
PATCH 3 adds basical devicetree binding for AXP803.
PATCH 4 adds support for the AXP803 variant in axp20x-rsb mfd driver.
PATCH 5 enabled the AXP803 MFD in Pine64 device tree.
PATCH 6 adds devicetree binding for the regulators in AXP803.
PATCH 7 adds support for the regulators in AXP803 in the axp20x-regulator
PATCH 8 enabled the regulator MFD cell in AXP803.
PATCH 9 adds a DTSI file for AXP803, just like what have been done for other
PATCH 10 enabled the regulators on Pine64.
PATCH 11 enabled Wi-Fi support on Pine64, which required DLDO4 and ELDO1
