Hey, guys,

Thomas's words might seem a bit harsh, but he really does understand what
Linus's reaction will be.  And Thomas's words are much less harsh than the
ones that Linus would likely choose.  I wish we had a good example of a
common-clock structure elsewhere in the kernel, but the fact is that ARM has
a much wider variety of SoCs than pretty much any other architecture.  So we
might as well get something put in place to start with that will have a
decent chance of standing the test of time (and therefore being something
that Linus is likely to approve of).

Could you please take a look at what Thomas suggested (
and give it a try?

                                                       Thanx, Paul
