Ivan,
I'm looking at the USB patches you posted in November. I'd like
to test them on a dragonboard I've got here. Could you possibly send
me your dts file for the dragonboard, or let me know where I might
get one with correpsonding bindings for the dragonboard (apq8074)?
Thanks,

It looked as if there is one queued for 3.14 here:

Well, you will not get too far with just these files. I am using
DTS files available in CAF repository with new Qualcomm clock
controller driver and one ugly patch which "port" regulator drivers
to upstream kernel.
USB3.0 patches are not really tested because I can not
get one of the PHY clocks up.
USB2.0 driver is working fine with following DTS bindings.

Ivan

Thanks very much.
I'm also working with a tree with some hacked-in regulators and a new
qcom clock controller.
I seem to be missing the driver for the chipidea block. I don't have
anything in my tree
with a compatible string of "qcom,ci-hdrc". I do have an ehci-msm.c file, with
a compatible string of "qcom,ehci-host". Sorry for asking newbie
questions, but I'm
trying to figure out the relationship between the different files,
drivers and IP blocks, and
which are applicable to the OTG port on the dragonboard.
(I did find that the other ports all seem to go through external USB hub chips).
Can you tell me what driver in your tree has the compatible string of
"qcom,ci-hdrc"?
Thanks for any direction you can provide.

OK, it looks like the part I need is in the patchset here:
https://lkml.org/lkml/2013/11/11/310
These patches add DT support to drivers/usb/chipidea/ci_hdrc_msm.c
Have there been any other updates to either this or
drivers/usb/phy/phy_msm_usb.c since November?
Thanks,
-- Tim

No. v4 for USB PHY driver and v0 for Chipidea driver.
I have v2 for Chipidea driver, but didn't contain any
functional changes, just patch description is improved.
