[PATCH v6 0/8] AXP8x3 AC and battery power supply support

[Oskari Lemmela]

AXP813 AC power supply support with input current and
voltage limiting support.

AXP803 AC and battery power supply support.

Changes in v6:
* Collected tags
* Rebase to master
* Dropped AXP803 compatible patches

Changes in v5:
* Return correct input current limit for values 0x6 and 0x7
* Add specific compatibles for AXP803
* Change commit messages
* Add Vasily Khoruzhick Pinebook DTS patch

Changes in v4:
* Change order of axp20x-gpio in axp20x.c
* Fix indentation and spaces to tabs in axp20x.c

Changes in v3:
* Reorder ac_power_supply DT node
* Rename axp20x_ac_power_set_property function
* Split mfd commit 

Changes in v2:
* Reuse axp813 compatibles for axp803
* Refactor axp20x_ac_power.c

My OCD-dar is going crazy.

Why haven't you used the same alignment as is already there?

If it starts to run over 80-chars then bring the others back.

Also why is there a single liner shoved in the middle of the
multi-line entries?  Please move the singles to the top or the
bottom.

Hi Lee,

Could you please reformat it in the way that makes your OCD-dar happy?
It would be really nice to get
AC and battery support for APX8x3 merged -- it'll make Pinebook and
Teres-I pretty well supported by mainline kernel.

Thanks,
Vasily

I'm afraid not, for a multitude of reasons.

The most important of which surround testing.

That's great.  A worthy cause indeed.  So I'm sure you guys will want
to turn the patch around in short order so that it's applied in time
for the next merge window.

Aren't the MFD cells probed in order?

In that case, it makes little sense to short order them for this
particular device (X-Powers PMICs in general). It will just make the
system boot slower because of probe deferring.

Why? As explained by Chen-Yu in v3[1], axp-gpios can be muxed as
regulators, thus should be probed before axp-regulators. axp-adc is
often used by axp-battery, axp-usb-power, axp-ac-power, thus should be
probed beforehand as well.

For the alignment that also triggered your OCD, I can send you a patch
the day you merge this one if it can help. I sent a few patches for this
driver that didn't respect the alignment so I'm fine fixing the mfd
cells (and eventually re-order them as I saw a few axp-gpio cells being
declared after axp-regulators).

Does that make this patch OK for you, Lee?

Thanks,
Quentin

If there are inter-dependencies between the devices, it makes sense to
keep them in the most efficient order.

That's fine.  Please send the patch (based on this set) right away.

Since Oskari sent a new version with an alignment fix patch and you
merged that version, I assume I do not have any work to do anymore on
this matter.

Thank you all for the patches,

I sent patch set v8 which contains ChenYu's re-align patch and
this patch rebased top of it.

Re-align patch will make number of whitespaces consistent in axp20x.c

Since this series has been fully reviewed, and the devices it
adds/enables aren't critical, i.e. won't cause the system to fail
if the drivers are missing, I've merged the dts patches for 4.21.

Hopefully Sebastian and Lee will get around to merging the driver
patches.

Thanks.
