Hi,
this series includes support to manage the transfer descriptors with an
linked list to manage a dynamic amount of data being enqueued in hardware.
It also addresses the isochronous support for the chipidea udc
and removes not needed lock state juggling.
The series applies on current
This patch removes the limitation of having a limited amount of only
four active tds on one endpoint. We use the linked list implementation
to manage all tds which get added and removed by hardware_{en,de}queue.

The implementation is derived from the fsl_udc_core code in
fsl_ep_enable and makes basic iso handling possible.

Changes since v1:
- fixed coding style issues mentioned by Sergei
There is no need to call ep_queue unlocked inside the own driver. We
move its functionionality into an unlocked version.
This patch removes potential unlocked timeslots inside
isr_setup_status_phase and isr_get_status_response, in which the lock
got released just before acquired again inside
Instead of having a limited number of usable tds in the udc we use a
linked list to support dynamic amount of needed tds for all special
gadget types. This improves throughput.
This patch also adresses a possible momory leak in _ep_nuke found
while porting the request handling to an linked list.
A static count of transfer descriptors was used everywhere in the driver
with the fixed number 4. This patch adds a define, named TD_COUNT, and
replaces all users of this value. This way its possible to have only one
parameter to change and limit the amount of tds per transfer.

Hello,
I am studying the isp1760-hcd code, trying to figure out the logic of the data
flow going in and out of the driver.
I have a few gaps in my understanding and was hoping to get help from you guys:

isp1760 to scan

This patch (as1661) fixes a rather obscure bug in ehci-hcd. In a
couple of places, the driver compares the DMA address stored in a QH's
overlay region with the address of a particular qTD, in order to see
whether that qTD is the one currently being processed by the hardware.

Add support for the usb controller in AR933x platform.
The processor is big-endian so all multi-byte values of the usb
descriptors must be converted explicitly. Another difference is that
the controller supports both host and device modes but not OTG.
