I would like to add CDP (charging downstream port) capability over my
OTG port in host mode. I am using an iMX6q platform with Chipidea HDRC
(highspeed dual role controller) with 4.1 kernel.
Looked at a bunch of documents like USB Battery Charging Specification
and USB Power Delivery specification

We are developing a custom USB device on a iMX6q platform with a Chipidea
HDRC. The device uses a single NCM interface for communication with another
OTG device i.e. Chipidea HDRC again. I see very poor iperf UDP performance
after role reversal with iperf server running on gadget.
Kernel: 3.10.17

I am developing a custom USB device on a iMX6q platform (Wandboard)
Chipidea HDRC (highspeed dual role controller). The HID interface
consists of a single Interrupt IN ep and ep0. It is required to send
HID reports from Host to Gadget over ep0 (with set_report cmd on
hidraw interface) in OUT direct

Thanks
