I think I prefer the original wording. The attribute is really about
setting the register refresh rate at the hardware level. The fact that
register cache lifetime in the driver can be adjusted accordingly is an
optional implementation detail IMHO.

Why change? All other units are singular in the file.

Killing an innocent blank line ;)

I'm fine with all the rest.
