Hi all,
this series fixes an issue which leads the hardware to get stuck after reading
dirty data from the shared memory mapped data of qheads and Transfer
Descriptors. It also changes the code to be more precise with the constraints
from the datasheet.
This series includes support to manage the Transfer Descriptors with an
linked list and have an dynamic amount of data being enqueued in hardware.
It 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.
Regards,
Michael
