Subject[PATCH 1/3] mfd: max77693: Add defines for charger current control
Message-ID<slNF7-1NX-1@gated-at.bofh.it>
This prepares for an updated regulator and charger driver. The defines
are needed to set the maximum input current and the fast charge
current.

This shouldn't be separate patch, because:
1. You are touching later power and regulator so this patch should be
applied to one and then pulled by other... a lot of unneeded work.
2. It is difficult to find which new code is needed for which driver.

Simpler approach might work - when changing the regulator or psy driver,
just change the header as needed. Unless there are conflicts and both of
them need the same?

Best regards,
Krzysztof

No, no conflicts. I will change the header as needed and won't do a
separate patch.

Thanks,
