From: Greg KH

2.6.36-stable review patch. If anyone has any objections, please let us know.

------------------

From: Axel Lin <axel.lin@xxxxxxxxx>

commit 2f7dceeda4708f470fd927adb3861bd8ebbe2310 upstream.

MCLKDIV bit of Register 04h Clocking1:
0 : Divide by 1
1 : Divide by 2

Thus in the case of freq <= 16500000, we should clear MCLKDIV bit.
