[PATCH resend v2 0/9] mfd: axp20x: Add support for AXP809 PMIC

From: Chen-Yu Tsai <hidden>
Date: 2016-03-29 09:30:10

Hi everyone,

This is a resend of v2 of the AXP809 PMIC support series. This adds
support for X-Powers' AXP809 PMIC. This is the primary PMIC accompanying
Allwinner's A80 SoC. For now, only the power button (PEK) and regulators
are supported. These are supported using existing axp20x drivers.

Driver patches are based on v4.6-rc1, while DT patches are based on
Maxime's sunxi/dt-for-4.7 branch.

Some regulator patches were merged into v4.6-rc1. Those have been
dropped from this series. Other than that there are no changes.

Patch 1 adds a MAINTAINERS entry for the X-Powers AXP PMICs.
I list myself as the maintainer.

Patch 2 adds AXP809 to the axp20x bindings.

Patch 3 adds AXP809 support to the axp20x mfd driver.

Patch 4 adds AXP809 support to the axp20x regulator driver.
This patch depends on patch 3.

Patch 5 adds a dtsi file for AXP809.

Patch 6 enables AXP809 support on the A80 Optimus board.

Patch 7 enables AXP809 support on the Cubieboard 4.

Patch 8 disables the dummy regulators from sunxi-common-regulators.dtsi
on the A80 Optimus board. These aren't used in the board DTS anymore.

Patch 9 disables the dummy regulators from sunxi-common-regulators.dtsi,
on the Cubieboard4. These aren't used in the board DTS anymore.


Regards
ChenYu

[PATCH resend v2 9/9] ARM: dts: sun9i: cubieboard4: Disable dummy regulators vcc3v0, vcc3v3, vcc5v0

From: Chen-Yu Tsai <hidden>
Date: 2016-03-29 09:28:54

These 3 regulators are provided in sunxi-common-regulators.dtsi.
3.0V/3.3V and 5.0V are commonly used voltages in Allwinner devices.
These dummy regulators provide a stand-in when bindings that require
one, but the real regulator is not supported yet.

Since these are no longer needed, we can disable them.

[PATCH resend v2 6/9] ARM: dts: sun9i: a80-optimus: Add AXP809 PMIC device node and regulators

From: Chen-Yu Tsai <hidden>
Date: 2016-03-29 09:28:57

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.

[PATCH resend v2 3/9] mfd: axp20x: Add support for AXP809 PMIC

From: Chen-Yu Tsai <hidden>
Date: 2016-03-29 09:29:01

The X-Powers AXP809 is a new PMIC that is paired with Allwinner's A80
SoC, along with a slave AXP806 PMIC.

This PMIC is quite similar to the earlier AXP223, though the interrupts
and regulator have changed a bit.

This patch adds support for the interrupts and power button of the PMIC.

This PMIC is quite similar to the earlier AXP223, though the interrupts
and regulator have changed a bit.

This patch adds support for the interrupts and power button of the PMIC.

Applied, thanks.

Could you also merge the MAINTAINERS patch ("MAINTAINERS: Add entry for
X-Powers AXP family PMIC drivers") and push an immutable tree for Mark
to merge the regulator patch?

Thanks again.

[PATCH resend v2 4/9] regulator: axp20x: support AXP809 variant

From: Chen-Yu Tsai <hidden>
Date: 2016-03-29 09:30:13

The X-Powers AXP809 PMIC has a similar set of regulators as the AXP221,
though a few LDOs were removed, and a new switch output added. Like the
AXP221, AXP809 also has DC1SW and DC5LDO, which are internally chained
to DCDC1 and DCDC5, respectively.

Add support for this new variant. Also remove the "axp22x_" prefix from
DC1SW/DC5LDO supply handling code, as the AXP809 uses it as well.

[PATCH resend v2 8/9] ARM: dts: sun9i: a80-optimus: Disable dummy regulators vcc3v0, vcc3v3, vcc5v0

From: Chen-Yu Tsai <hidden>
Date: 2016-03-29 09:30:56

These 3 regulators are provided in sunxi-common-regulators.dtsi.
3.0V/3.3V and 5.0V are commonly used voltages in Allwinner devices.
These dummy regulators provide a stand-in when bindings that require
one, but the real regulator is not supported yet.

Since these are no longer needed, we can disable them.

[PATCH resend v2 5/9] ARM: dts: sunxi: Add dtsi file for AXP809 PMIC

From: Chen-Yu Tsai <hidden>
Date: 2016-03-29 09:30:58

The AXP809 PMIC is used with the Allwinner A80 SoC, along with
an AXP806 PMIC as a slave.

This patch adds a dtsi file for all the common bindings and default
values unrelated to board design. Currently this is just the interrupt
properties.

Hi Lee,

Hi everyone,

This is a resend of v2 of the AXP809 PMIC support series. This adds
support for X-Powers' AXP809 PMIC. This is the primary PMIC accompanying
Allwinner's A80 SoC. For now, only the power button (PEK) and regulators
are supported. These are supported using existing axp20x drivers.

Driver patches are based on v4.6-rc1, while DT patches are based on
Maxime's sunxi/dt-for-4.7 branch.

Any news on this series? It's been almost 2 weeks since I reposted
them for 4.7, and longer since I first posted v2.


Regards
ChenYu

Some regulator patches were merged into v4.6-rc1. Those have been
dropped from this series. Other than that there are no changes.

Patch 1 adds a MAINTAINERS entry for the X-Powers AXP PMICs.
I list myself as the maintainer.

Patch 2 adds AXP809 to the axp20x bindings.

Hi everyone,

This is a resend of v2 of the AXP809 PMIC support series. This adds
support for X-Powers' AXP809 PMIC. This is the primary PMIC accompanying
Allwinner's A80 SoC. For now, only the power button (PEK) and regulators
are supported. These are supported using existing axp20x drivers.

Driver patches are based on v4.6-rc1, while DT patches are based on
Maxime's sunxi/dt-for-4.7 branch.

Any news on this series? It's been almost 2 weeks since I reposted
them for 4.7, and longer since I first posted v2.

Nope, no news yet.

I'm swamped and will get round to them in good time.

Some regulator patches were merged into v4.6-rc1. Those have been
dropped from this series. Other than that there are no changes.

Patch 1 adds a MAINTAINERS entry for the X-Powers AXP PMICs.
