This the alternative version of the support for Exynos 421x USB 2.0 PHY
in the Generic PHY framework. In this version the support for Exynos
4210 and 4212 was joined into one file.

Hi,
Me and Kishon were discussing for quite a long time the way how Exynos 4
should be handled. I have decided to post the original patches and try
to make an alternative version with support for Exynos 4210 and 4212 joined
in one file. I have prepared two versions. The first one has 506 lines (vs
563 when two files are used). When doing the second version I was a little
more aggresive in removing code. This was done at a cost of adding if's
deciding which SoC version the driver is dealing with in some internal functions.
This resulted in a better number of removed lines - the second version has
only 452 lines (vs 563 original and 506 version 1).
Personally I like the original approach. One of my goals was to create a driver
that would be clear and easy to understand. I see that this was done at a cost of
having the code a little longer.
The first alternative version mostly was done by removing duplicate defines of
register values. The code clarity suffers a bit, but is still acceptable in my
opinion.
As to the second alternative version. It has the fewest lines, but I am not an
enthusiast of using "if this is SoC" in functions.
Anyway - please have a look at these two alternative versions in addition to
looking at the original patch "phy: Add new Exynos USB PHY driver".
Best wishes,
Kamil Debski
