From: Beomho Seo <redacted>

This patch adds device driver of max77843 charger. This driver provide
initialize each charging mode(e.g. fast charge, top-off mode and constant
charging mode so on.). Additionally, control charging paramters to use
i2c interface.

I can't take it as is, since it depends on the private header file
of PATCHv1.

Could you Please merge that your git tree ?

Hi,

... and again we are adding a new driver for very similar chipset to
already supported. I looked at spec and the charger's registers are
almost the same as for max77693. Their layout and addresses are the
same. I see some minor differences, probably the most important would
be different values current (fast-charge, top-off). But still 90% of
registers are the same... Do we really have to add new driver?

Best regards,
Krzysztof

Hi,

Thank you for your comment. As you say, both chip set are similar.
But new driver need for support max77843. It is support different below
- Provide Battery presence information.

Another set of power supply properties could be added for that chip.
This way the get_property() function would be the same but actually the
POWER_SUPPLY_PROP_PRESENT won't be called for max77693.

- Can OTG FET control.

Where the OTG FET feature is it enabled in your driver? I couldn't find
it.

Sorry. This driver don't control OTG FET feature.

- Bigger Fast charge current, Top Off current Threshold selection.
- Various and bigger OTG current limitation.
- Bigger primary charger termination voltage setting.
- Different maximum input current limit selection(Different step).

Yes, I mentioned some of these differences (the Fast/top-off
differences). These are differences in values so it does not require new
driver. There is need to develop new driver just to support different
current (3.0 A instead of 2.1 A) or voltage threshold.

They are different charging current, OTG current limitation, top off current,
charging limitation value. In case OTG current limitation different not
limitation value but using register bit(max77843 use[7:6] max77693 use[7]
bit only). Even if this driver not support all feature, some register
different with max77693(support value, use register bit).

If this driver will combined with max77693 may even be beneficial for
new Maxim driver. But the present, this driver is related with
max77843 core driver and max77843-regulator. So I hope this driver
merge first. And then will extend two driver(max77843 charger and max77693 charger).

I still prefer merging common drivers into one instead of creating
some more of them.
However I understand your point and I am not entirely opposed against.
Especially that you invested quite a bit of time for developing this
and my feedback was quite late. To summarize I am fine with your
approach.

Best regards,
Krzysztof

Then, Can I request merge this patch ?
