[PATCH 0/9] mfd: axp20x: Add support for AXP809 PMIC

[Chen-Yu Tsai]

Hi everyone,

This series adds support for X-Powers' AXP806 PMIC. This is the secondary
PMIC accompanying Allwinner's A80 SoC. For now, only the regulators are
supported. While the AXP806 supports standalone operation, no hardware
exists, so this will not be supported.

Patch 1 adds AXP806 to the axp20x bindings.

Patch 2 adds AXP806 support to the axp20x mfd driver.

Patch 3 fixes regulator output adjustment during regulator registration
so it doesn't fail if the higher or lower bounds of its voltage constraints
don't match up with the regulator's voltage granularity.

Patch 4 adds AXP806 support to the axp20x regulator driver.

Patch 5 adds the unused SW switch output of the AXP809 PMIC on the A80
Optimus board. This was accidentally left out of the AXP809 series.

Patch 6 adds the unused SW switch output of the AXP809 PMIC on the
Cubieboard 4. This was accidentally left out of the AXP809 series.

Patch 7 enables AXP809 support on the A80 Optimus board.

Patch 8 enables AXP809 support on the Cubieboard 4.

Patch 9 disables EHCI1 on the A80 Optimus board.
