Technically the HW we are trying to program here differs in terms of
clocking, the LUT definitions and many more. It will definitely make
debugging much more troublesome if we try to accommodate multiple versions of
CPUFREQ-HW in the same code.

Thus to keep it simple, easy to read, debug, the suggestion is to keep it
with "v1" tag as the OSM version we are trying to put here is from OSM1.0.

That is a valid point and is always a case with so many drivers. What
I am concerned about is how much code is common across versions, if it
is 5-70%, or more, then we should definitely share, arrange to have
callbacks or ops per version and call them in a generic fashion instead
of writing a new driver. This is what's done across
drivers/frameworks, etc.


The code sharing here between versions should be very minimal as most portion of the code here in V1 would focus on programming to prepare the LUT to be further read by the driver, the programming in itself is huge for v1. I am okay if you move the v1 in a different file and invoke based on version.
