Nothing will break for OMAP3, but OMAP4 USB host will break (e.g. Panda board).
OMAP5 USB host was never working so it doesn't matter there.

To make sure nothing breaks, we need at least these 2 patches to go in together with mfd changes.

[PATCH v8 08/14] ARM: dts: omap4: Update omap-usb-host node
[PATCH v8 09/14] ARM: dts: omap5: Update omap-usb-host node

Any suggestions about how we can proceed?

cheers,
