The "host1" port (AKA the dwc2 port that isn't the OTG port) on rk3288 has a hardware errata that causes everything to get confused when we get a remote wakeup. It appears that the "port reset" bit that's in the USB phy (located in the rk3288 GRF) fixes things up and appears safe to do. This series of patches exports the "port reset" from the PHY and then hooks it up to dwc2 through a quirk. I've tested this series atop a bit of a conglomeration of Heiko's github "somewhat stable" branch (v4.3-rc3-876-g6509232) but with Greg KH's usb-next merged in. These patches currently conflict with patches that I posted previously to enable USB wakeup from S3, specifically: * https://patchwork.kernel.org/patch/6727081/ * https://patchwork.kernel.org/patch/6727121/ ...those patches no longer apply anyway, so presumably they need to be reposted and I can do so later atop these patches.
