[PATCH 0/3] arm64: allwinner: Enable AXP803's USB power supply

[Chen-Yu Tsai]

From: Chen-Yu Tsai <wens@csie.org>

Hi everyone,

This series follows up on the A83T USB OTG series. The USB power supply
portion of the AXP803, the PMIC used with the A64, is identical to the
part in the AXP813/AXP818, used with the A83T.

This series enables the USB power supply in the AXP803 using the AXP813's
compatible string as a fallback. The per-model compatible string is still
added as a contigency.

Patch 1 adds an mfd cell for the USB power supply, to the AXP803.

Patch 2 adds a device node for the USB power supply.

Patch 3 enables the USB power supply on the Bananapi M64.

Unfortunately the original Pine64 does not wire up the USB power supply,
and I don't have any other A64 boards.

The mfd patch can go in through the mfd tree. There are no compile-time
dependencies. We, sunxi, can take the DT patches.

Please have a look.


Regards
ChenYu

[PATCH 1/3] mfd: axp20x: add USB power supply mfd cell to AXP803

[Chen-Yu Tsai]

From: Chen-Yu Tsai <wens@csie.org>

The AXP803 has a VBUS power input. Its functionality is the same as the
one found in the AXP813. Now that the axp20x_usb_power driver supports
this variant, we can add an mfd cell for it to use it.

[PATCH 3/3] arm64: dts: allwinner: a64: bananapi-m64: Enable PMIC USB power supply

[Chen-Yu Tsai]

From: Chen-Yu Tsai <wens@csie.org>

The Bananapi M64 has a micro-USB connector with USB OTG support (that
is already enabled). VBUS from this connector is wired to the PMIC's
VBUS input.

Enable the PMIC's USB power supply on this board, and also hook it up
to the USB PHY.
