How is this clock used on the board?

As a convention, hyphen instead of underscore should be used in node
name.  I would suggest to simply name it like regulator-usbh1vbus to
save additional hyphens.

Since commit 0dbcdc0622ea (mmc: core: enable support for the standard
"wakeup-source" property), enable-sdio-wakeup becomes a legacy property.
Please use the new standard one.
