4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Richard Genoud richard.genoud@gmail.com
commit 6a4a4595804548e173f0763a0e7274a3521c59a9 upstream.
Clearfog boards can come with a CPU clocked at 1600MHz (commercial) or 1333MHz (industrial).
They have also some dip-switches to select a different clock (666, 800, 1066, 1200).
The funny thing is that the recovery button is on the MPP34 fq selector. So, when booting an industrial board with this button down, the frequency 666MHz is selected (and the kernel didn't boot).
This patch add all the missing clocks.
The only mode I didn't test is 2GHz (uboot found 4294MHz instead :/ ).
