The compatibility string is generic on purpose as it is not intended to 
be SoC specific but work on all new iproc SoCs that have the proper 
fixes in place for this block (unlike bcm2835 and cygnus class devices 
which can only do 32-bit accesses).  I could call it brcm,sdhci-iproc-v2 
if that is better or leave it as is.  Please let me know your preferences.

I just sent out v2 of the patch with additional details in the device 
tree bindings document.  Please let me know if this covers your 
concerns.  The SDHCI controller binding is not SoC specific and is used 
in multiple SoCs going forward with the same binding.
