Hello,
Some time ago I had a pleasure to work on some kind of a simple
charger manager for u-boot. For checking battery charge level, cable
state, and some more info I made a common calls which were implemented in
board files, so actually it didn't base directly on PMIC framework. This
allowed making charger abstraction but it was a second power related
framework next to the PMIC.
From my side I would like to introduce its next version according to the
doc/README.power-framework documents "TO DO" list and some more...
In this RFC any comments about next version of power management framework
are welcome.
What new PMIC framework should provide?
How to extend it?
What can be fixed?
So, what should be done (in my opinion):
Can I suggest we try to build this with driver model if possible? It
seems like you will otherwise end up duplicating much of the plumbing
of that. For example, see 'struct device'.
Regards,
Simon
Yes, I also would like to take it into account - but I am not sure that
driver model is not too redundant for it?
If I well understand the current driver model - each driver can have
only one uclass, right? If yes, then for each previous listed ops we
need to register separate driver - isn't it too much for read one
register or turn on the led in the same physically device?
So maybe better is to register one "power" driver in driver model? And
the power uclass driver could init more then one class specific ops.
I just would like to keep it simply.
Thanks
