For the chipidea usb driver, if the dr_mode is not set, it will set
the device to otg mode by default, so here the dr_mode has not been
set for a long time. But some testcases need to parse the dr_mode from
DT and decide the follow-up test strategy, here set the dr_mode to otg
explicitly for QA's testcases.

The dr_mode is board specific property, so we normally don't put it in
dtsi file. Also, imx6qdl.dtsi is a common dtsi, therefore it's not a
correct place. I wonder you don't set dr_mode in other dts file which
include will imx6qdl.dtsi?

Thanks,
Xu Yang

Yes, our QA reported this issue against the imx6q-sabresd board, I 
thought dr_mode could be overwritten if board dts set the dr_mode, so 
this change will not impact existing boards. But as you said "we 
normally don't put it in dtsi file", I will move it to imx6q-sabresd.dts.

Thanks,

Hui.

Okay. You can move it to imx6qdl-sabresd.dtsi too. Then you can reuse
&usbotg {}.

Yes, for sure.
