Sounds excellent. Thank you!
There are a few groups to keep in touch with on this:
* The omap_hsmmc folks, of course
* Ohad Ben-Cohen has SDIO runtime PM patches¹, which I think should
be merged
* Kevin Hilman is working on converting omap_hsmmc over to runtime PM²
* Matthew Garrett is working on a patch to power down unused SDHCI
devices using runtime PM
