4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: John Hsu <kch...@nuvoton.com>
[ Upstream commit a1792cda51300e15b03549cccf0b09f3be82e697 ]
The clk_ref_div is not configured in the correct position of the
register. The patch fixes that clk_ref_div, Pre-Scalar, is assigned
the wrong value.
