I thought about this too but wasn't able to use chipidea with
MXC_EHCI_INTERNAL_PHY as it's called in fsl_udc.
that's a matter of writing the PHY driver, right ;-) It has nothing to
do with chipidea, actually :-)
Okay, I'll do. But
This series updates USB gadget driver fsl-usb2-udc.
Christoph Fritz (7):
usb: gadget: fsl_udc: simplify driver init
usb: gadget: fsl_udc: protect fsl_pullup() with spin_lock
usb: gadget: fsl_udc: convert to new ulc style
usb: gadget: fsl_udc: drop ARCH dependency
usb: gadget: fsl_udc
To initialize this driver use 'module_platform_driver' instead
of '__init' and '__exit'.

This patch removes redundant pointer to struct usb_endpoint_descriptor which
were missed in commit 79149b8:
usb: gadget: Update fsl_udc_core to use usb_endpoint_descriptor inside the
struct usb_ep
Due to clock framework regressions, this patch is only compile tested!

Hi to All,
after a while of testing and searching I can come up with a patch
that fixes g_ether - iperf for fsl_udc on ARM i.MX35.
The sad part is that this kind of fix is already implemented for
marvell mv_udc driver
Hi Neil,
thanks for you help.
What about the fix for mv_udc, shouldn't they have a similar
limitation? How do you explain?
Or maybe someone from Marvell has an answer?
Yes, we encountered the same issue, and I have answered your question several
hours ago.
Please have a look.
