[V9 PATCH 05/12] usb: phy: phy-mv-usb: use USB2 PHY driver for otg
Originaly, otg driver will call the callbacks in platform data for PHY initialization and shut down. With PHY driver, it will call the APIs provided by PHY driver for PHY initialization and shut down. It removes the callbacks in platform data, and at same time it removes one block in the way of enabling device tree for otg driver.

I did two of the mods sugested on olimex forums. 1) Remove R17. 2) Drop DDR speed to 96MHZ. The first improved the behavior a lot, but still have crashes. The second have almost eliminated them.

When you spin v2 could you note in the change log of each patch that includes both SoC and board of SoC and river code that the reason for this is to avoid breaking bisection?

USB3.0 Interrupt transfer in u-boot
Hello, I want to test USB keyboard for XHCI in u-boot and to do that i need the Interrupt transfer code in XHCI controller driver in u-boot. If possible, can you help me to give that piece of code or can you help me to figure out in kernel where can i find it so that i can try to replicate it in u-boot and make it work.
