Subject[PATCH resend v2 0/6] regulator: axp20x: Add support for AXP809 PMIC
Message-ID<rEUIi-50B-5@gated-at.bofh.it>
Hi everyone,

These are the remaining patches of my AXP809 PMIC support series. The
mfd parts and regulator fixes were merged in v4.7-rc1. What's left are
the AXP809 regulator driver and dts changes.

Patch 1 adds AXP809 support to the axp20x regulator driver. This patch
depends on patch 3, and patches already in regulator/topic/axp20x.

Patch 2 adds a dtsi file for AXP809.

Patch 3 enables AXP809 support on the A80 Optimus board.

Patch 4 enables AXP809 support on the Cubieboard 4.

Patch 5 disables the dummy regulators from sunxi-common-regulators.dtsi
on the A80 Optimus board. These aren't used in the board DTS anymore.

Patch 6 disables the dummy regulators from sunxi-common-regulators.dtsi,
on the Cubieboard4. These aren't used in the board DTS anymore.

Message-ID<rEUIk-50B-71@gated-at.bofh.it>
In reply to#1410411
The AXP809 PMIC is the primary PMIC. It provides various supply voltages
for the SoC and other peripherals. The PMIC's interrupt line is connected
to NMI pin of the SoC.

And we should just remove the include on his one.
