Hi,
A guy posted this fix on my blog. I couldn't make sense of it.
Thought I'd post it here. I'll send a proper patch file if

This one patch does too much to be reviewed easily.
One patch is supposed to modify/add one thing at a time in the kernel.
Separating platform specific code from imx-drm/imx-hdmi is one thing.
Adding support for multi-byte register access is something different.
i.e. Something like.
1/3 split
and stay within jz4740
so should apply easily on other trees.
If you would like to have them rebased to a different tree, please tell.
Thank-you

Call jz4740_clock_init before any uses of jz4740_clock_bdata occur. This
is in preparation for replacing uses of that struct with calls to
clk_get_rate, which will allow the clocks to be migrated towards common
clock framework devicetree.
