Subject[PATCH RFC 0/5] treewide: add USB OTG support for hammerhead
Date
This patch set adds USB OTG support for the LG Nexus 5 (hammerhead)
phone. My only question is related to patch #4 where the GPIO support
is added to bq24190_charger. Based on the information in the device tree
binding Documentation/devicetree/bindings/power/supply/bq24190.txt, I
should be using a gpio-hog. I'm not sure what my input pin would be for
this particular board since I can't find a publicly-available datasheet
for this board.

The USB OTG support works properly with this patch set. I am able to use
USB networking, and I'm also able to plug in a USB hub with a thumb
drive on the phone, and mount the drive.

All of the other msm8974-based boards in upstream use the
qcom,pm8941-charger (via the smbb node) that is defined in
qcom-pm8941.dtsi. USB networking works for me with that driver, however
I'm not able to get any devices connected to my USB hub to show up on
the phone, even when I port the GPIO code into that driver. I can see
the USB hub node with lsusb, but no devices on the hub.

Thanks in advance for any assistance that you can provide.
