Hi Matthias,
Thanks for the review. I Will address below comments and post changes in
new version.

Add interconnect support in dwc3-qcom driver to vote for bus
bandwidth.
This requires for two different paths - from USB master to
DDR slave. The other is from APPS master to USB slave.

Hi,
I am running kernel LTS 4.19 in an i.MX6 board with a 4G LTE modem, it
continually displayed following messages in a serial port tried and
failed to connect to LTE modem, are there any problems in kernel 4.19
LTS to support usb qmi protocol and LTE modem connection?

Hi,
this series adds the simple-pm ops to reinitialize the hub after a
suspend. For this reason I added the vdd-supply to ensure that vdd is
ready.

Currently the driver don't support pm_ops. These ops are not necessary
if the supply isn't switchable (always on). This assumptions seems to be
wrong because no one needs a powered hub during suspend-to-ram/disk.
So adding simple_dev_pm_ops to be able to switch off the hub during
suspend and to re
Add the optional voltage supply documentation. If not specified the

Currently we don't handle the supply. We need to add the supply support
to be able to switch the supply off e.g. during a suspend-to-ram
operation. So we can guarantee a correct (re-)initialization.

Currently the reset handler was always called to deassert the reset
line because assert the line was done during probe. Now if we want to
support pm by turn of the supply we need to call this routine twice and
the i2c_lock_bus is done twice too. To simplify that we can drop the
state and just do a

According to Greg KH, it has been generally agreed that when a USB
driver encounters an unknown error (or one it can't handle directly),
it should just give up instead of going into a potentially infinite
retry loop.
The three codes -EPROTO, -EILSEQ, and -ETIME fall into this category.
They can be

That was always my thought until I tried kernel 5.1 under the same
platform (nothing changed except the kernel version), the kernel 5.1
