Hi all, this series fixes an issue which leads the hardware to get stuck after reading dirty values from the shared memory mapped QHs and TDs. It also changes the code to be more precise with the constraints from the datasheet. It adds support to handle requests which spawns into several TDs. And additionally addresses the isochronous support for the chipidea udc and removes not needed lock state juggling. The series is based on Alexander Shishkins ci-for-greg branch.
