The TPS65917 chip is a power management IC for Portable Navigation Systems

This patch adds support for tps65917 mfd device. At this time only
the regulator functionality is made available.

What does the read do? You're not doing anything with the value.
This pad1 and pad2 stuff is not needed. I will remove this.
Then why is it in here?
Did you copy this code from somewhere, if so, where?
Okay, I just answered my own question. There is so much common code
in between this and palmas, there is no way I'm going to accept this
driver. Please merge it in with the palmas driver!
The chip is more like a subset of palmas with lot of register offset changes
and register bit field changes. Adding this would make it clumsy.
There could
be lot of checks. That is why i chose to write a new driver.
Palmas driver already supports palmas variants and tps659038. Merging
this would mean more and more checks :-/.
Then find an elegant way of representing the variants. I'm not
prepared to carry that much duplicated code in MFD. It's already
overladened and in need of an overhaul. This will exacerbate the
matter.
Okay. I am working on that.

Keerthy
