(Ugh, I just noticed the typo in that filename.  We should fix that.)

Let's make these core optional properties, documented in
Documentation/devicetree/bindings/mmc/mmc.txt instead of in
synposis-dw-mshc.txt, and also add support for them in sdhci_pltfm.c
by adding your "host->pm_caps |= .." lines to sdhci_get_of_property().

Please could you do that and resend?  The dw_mmc patch looks fine.

Thanks,

- Chris.
