Hi Cosmin,

Just one question inline from me (other than the build bot report that I'll
assume you'll fix for v3).

Otherwise looks like a nice cleanup to me.

I wonder a bit on whether it is worth splitting up, but that would be
rather messy to actually do so will leave that to the dt experts to comment
on.

Jonathan

This new text has me a little confused.  Previously we talked rounding, now it
is saying the value is multiplied (which would make it definitely not in micro
secs!)..  So are we papering over a driver bug here?

Hi Jonathan,

Let me try to make this one clear as it was my mess...

The multiplication is done internally by the device. I messed up in
this one as this value is clearly not in us but it is the raw value.
So, tecnically, there's nothing wrong in the driver as it just reads
this property and directly writes it. But of course this is misleading
and wrong from the bindings point of view.

That said, me and Cosmin did spoke about just having this property
'deprecated' and add a new one (the driver would need to be changed
accordingly) - no idea also about a new name for it :)

But for this round, Cosmin decided to have this stated on the
description and see what you and dt maintainers had to say about it and
if making it 'deprecated' is the way to go (or something else).
