This patch series works fine if we use the new dtb and new kernel.

However, booting a kernel with these series applied and using an old 
dtb we get a system with broken timer.

'sleep 1' takes something like 20 seconds in this case.

Oh, yes.  It breaks the compatibility with existing DTB.  Dropped the patches for now.

Anson,

We may need to query the clock rate and then decide how to set up those register bits?
