The status quo on i.MX6 is that if "over-current-active-high" is
specified in the device tree this is configured as expected. If
the property is missing polarity isn't changed and so the
polarity is kept as setup by the bootloader. Reset default is
active high, so active low can only be used with h
The polarity of the over current detection pin isn't configured on i.MX6/7
if it's unspecified in the device tree. So the actual configuration depends
on bootloader behavior which is bad.
So encourage users to fix their device tree by issuing a warning in this
case.

Up to now the polarity of the over current pin was hard coded to active
high. Use the already defined device tree properties to configure polarity
on i.MX25, too. In difference to i.MX6/7 use active high behavior if the
polarity is unspecified to keep compatibility to existing device trees.

On Motorola Mapphone devices such as Droid 4 there are five USB ports
that do not use the same layout as Gobi 1K/2K/etc devices listed in
qcserial.c. So we should use qcaux.c or option.c as noted by
Dan Williams .
The ff/ff/ff interfaces seem to always be UARTs on Motorola devices.

The current OC (Over Current) handling does not consider the default
and bootloader OC setting well, in this commit, we reset OC setting
according to dts value:
- If property "disable-over-current" is set, we will disable OC at
code; otherwise, we will enable OC.

I noticed that phy_pm_runtime_get_sync() and phy_pm_runtime_put() are not
currently doing anything for phy-mapphone-mdm6600, only the sysfs interface
for works for "auto" and "on".
This is because of the shared GPIO pins between mdm6600 USB port and n_gsm
port. We have not enabled runtime PM for t
