This series is based on commits that can be found in the git tree here: https://github.com/thierryreding/linux/commits/staging/xhci I have included the patches I've used from that tree as patches 1-5. The above patches were submitted for review back in May: https://lkml.org/lkml/2015/5/4/574 The approach taken in these patches was deemed not appropriate (treating the XUSB as a MFD). In patch 6 I add the bindings based in those submitted for review here (with a few modifications currently required by the driver): https://www.spinics.net/lists/linux-usb/msg130940.html I have included my changes to the original patch series in patch 7. With these modifications the patch series builds and works, but is rather hacky. Devices for the mailbox driver and xHCI driver are now created in the xusb driver (still under the mfd directory for now - it will be moved before this series is submitted properly). As the child devices use infrastructure which expects the device to be associated with a of_node, it has been necessary to point the child device at the parents of_node where this is needed. This approach did not seem viable for the mailbox API, so to get that working the child device node was pointed to the parents of_node (in tegra_xusb_add_device). The unfortunate side effect of this is that upon device creation the parents probe routine gets called... Not good. Patch 8 attempts to resolve this. When passing the parents device node to the mailbox API, the mailbox's receive callback was raising errors as that function is looking for the drvdata stored in the child's device node, but getting the parents. This patch jumps though a few hoops to get to the child's device node. Unfortunately, whilst the receive callback seems to be getting the right drvdata, USB3 devices are being enumerated as USB2 devices rather than USB3 devices, so something is clearly not right. I'm posting these patches in the hope that someone can point me in the right direction. Is there a better approach I'm missing? Any ideas why devices aren't being enumerated as USB3?
