[PATCH 0/4] regulator: Add X-Powers AXP717 PMIC support

[Andre Przywara]

This patch series adds support for the X-Powers AXP717 PMIC, which is 
used recently on new boards with Allwinner SoCs.
Allwinner's BSP code often speaks of the AXP2202, this seems to be the
same chip, at least a boot0 AXP2202 driver happily drove a chip labelled
AXP717.

Patch 1 fixes a typo in some macro names for the AXP313a PMIC, I just
realised that during some copy&paste action. It's just an identifier
rename, so not a backport candidate, I'd say.
Patch 2 adds the compatible string to the binding document.
Patch 3 is the MFD part, describing the regmap and all the interrupts.
So far we support the regulator and power key devices, the USB and
charging devices will follow later.
Patch 4 adds the voltage regulator rails, this part is crucial to enable
any board using this PMIC, as we depend on those rails even for basic
devices.

Please note that I could not test this driver myself, but had success
messages from others. It would be good to hear from Ryan and Chris
here on the list, with a Tested-by: tag.

This series is based on next-20240308 for now. I will send a rebased
update after the merge window, but wanted to start discussion and review
now.

Please have a look!

Cheers,
Andre

[PATCH 1/4] regulator: axp20x: fix typo-ed identifier

[Andre Przywara]

The registers to set the X-Powers AXP313 regulators are of course
"CONTROL" registers, not "CONRTOL" ones.

Fix the typo in the header file and in its users. No functional change.

[PATCH 2/4] dt-bindings: mfd: x-powers,axp152: document AXP717

[Andre Przywara]

The X-Powers AXP717 is a PMIC used on some newer Allwinner devices.
Among quite some regulators it features the usual ADC/IRQ/power key
parts, plus a battery charger circuit, and some newly introduced USB
type-C circuitry.
Like two other recent PMICs, it lacks the DC/DC converter PWM frequency
control register, that rate is fixed here as well.

Add the new compatible string, and add that to the list of PMICs without
the PWM frequency property.

[PATCH 3/4] mfd: axp20x: add support for AXP717 PMIC

[Andre Przywara]

The AXP717a is a PMIC chip produced by X-Powers, it can be connected to
an I2C or RSB bus.

It's a rather complete PMIC, with many regulators, interrupts, an ADC and
battery charging functionality. It also offer USB type-C CC pin
handling.

Describe the regmap and the MFD bits, along with the registers exposed
via I2C or RSB. This covers the regulator, interrupts and power key
devices for now.
Advertise the device using the new compatible string.

[PATCH 4/4] regulator: axp20x: add support for the AXP717

[Andre Przywara]

The X-Powers AXP717 is a typical PMIC from X-Powers, featuring four
DC/DC converters and 15 LDOs, on the regulator side.

Describe the chip's voltage settings and switch registers, how the
voltages are encoded, and connect this to the MFD device via its
regulator ID.

Thanks Andre, tested on an Allwinner H700-based board (Anbernic RG35XX+) with successful bringup of DRAM, boot and regulator reporting via /sys/kernel/debug/regulator/regulator_summary. 

Battery charging not tested but according to vendor datasheet this functionality is internal to the PMIC and can complete without reference to the host, with informational reporting and charging parameters optionally modified by host over I2C or RSB.

Do you plan to put the Type-C logic under a subnode, or should the
Type-C connector node go directly under the PMIC node? Either way, the
binding probably needs to be updated for that.

I haven't looked into this yet, so cannot say which way to go. I
definitely consider this some non-trivial task, so indeed wanted to push
this off to later.
For now there is a device (Anbernic RG35XX) with that PMIC, so we need at
least the regulators to unblock this. USB support is not critical for now.

Ah, I indeed missed this one. I think the former PMICs had this
batter->VBUS boost regulator hidden, controlled entirely by the PMIC?
I will need to check if exposing this will present any surprises. I
guess this goes together with the USB-C support, to have role switching,
unless this appears on some device with just USB-A or micro-B.
I will check what it takes to add this one, the regulator itself looks
easy.

Thanks!

I don't think there was such a boost regulator on previous PMICs. It was
just a passthrough, which is why on some boards such as the Cubietruck
there is an external boost converter to put out 5V when just the battery
is used.

All applied and sent for build testing.  If everything works out, I'll
send out a pull-request to an immutable branch shortly.

Okay, these are building okay based on v6.8.

I'll send out a PR once I can rebase tem onto v6.9-rc1.

Did you mean v6.10 merge window? Or is there a plan to merge this into
6.9 still?

Also I found some issue with the LDOs' supply voltage: there are not
all the same, as described right now. Fix is quite easy, how do you
want to take this? As a follow up patch? And would this be squashed or
kept separate?
Or do you want we to send a new version? If yes, based on what branch?

Thanks,
Andre

Yes - off-by-one!

Please submit a fix-up.

I'll sent out a new (ib-mfd-regulator-v6.9-1) PR based on this one.

Just recreated ib-mfd-regulator-v6.10 for all the OCD types (like me!).
