Hi Drew,

Based on Yangtao's version, I cooked an updated version in last
development window but still can't complete it and met some issues
which need the clk/pll register document.
IIRC, the document was released a few days ago before soc tree frozen.

It's nice if you can continue the effort! I'll read the sdhci driver
soon.

Thanks
