In v3.5, it has at least the following problems: - warning dump during bootup - hang during suspend - prevents CORE powerdomain from entering retention during idle (even when no USB devices connected.) This demonstrates that this driver has not been thoroughly tested and therfore should not be enabled in the default defconfig. In addition, the problems above cause new PM regressions which need be addressed before this driver should be enabled in the default defconfig. Signed-off-by: Kevin Hilman --- Tony, this applies to your current fixes branch. Please queue up for v3.5-rc so this PM regression is fixed in v3.5.
