What happend to that patch? It did not show up in any new series. Is it
queued anywhere?
This patch was not required to get the single instance usb supported
on am335x.

usb: multi phy support
Hi Felipe, AM335x SoC's used in boards like beagle bone has two instances of USB modules (2.0) at the hardware level, each having a dedicated phy. Currently in mainline, only one instance of USB is supported (including a fix in your latest pull request). To support multi instance, the biggest obstacle is lack of multi phy support for usb phy's of same type. Earlier Kishon was working on usb phy device tree support, later it was seen that generic phy layer was preferred. And Kishon posted a couple of versions on generic phy framework, latest being on 26th September 2012, but I could not see follow up's on that series. It seems Kishon is not now working on generic phy support. Let me know your opinion/suggestions on supporting usb phy's of same type. We are trying to get multi USB instance support in mainline for AM335x. Regards Afzal

Yes, we need it for 3.8, please consider it for inclusion in 3.8 merge window. First one restores capability to support at least one instance of musb. Without it, even a single instance can't be supported as change which is reverted by it was made along with multi phy changes and nop transciever dt support, both other changes didn't make it to mainline. Second one corrects binding document; changes were made in driver as per review comments, but documentation was not updated. second one is clearly not for -rc.

RE: [PATCH 0/5] usb: musb: am335x support
Hi Daniel, * Daniel Mack, November 03, 2012 1:06 AM: I'm testing these patches with an AM33xx board that has the first musb port wired to an USB type A plug, but it doesn't yet work for me. So there is no host interface registered. I'm unsure on how to fix this, and I didn't get an answer yet to that question when I asked Felipe about how interface drivers like dsps are supposed to act in order to get host mode back after the recent musb cleanups. What type of hardware do you test this with? Does host mode work for you? To add to those details mentioned by Ravi, This was tested on Beagle Bone with USB0 as usb-ethernet. For purely Kernel part, this series is sufficient (along with dependency mentioned in cover letter), considering the fact that dt node is strictly not a part of Kernel. To test this series, node for usbss should be present in dt. Example in dt documentation can be pasted onto dtsi file to get USB0 working. Alternatively, you can fetch from, git://gitorious.org/x0148406-public/linux-kernel.git usb it has dt updated with usbss node.
