This board has fixed conenction between VBUS and DCIN, so if it is powered from DCIN and someone will try to connect it to the PC as a peripheral, they'll get PC's VBUS shorted to the power supply connected to DCIN. Depending on voltage difference between DCIN and PC's VBUS, you can get overcurrent condidion and PC's port shutdown. The board is not entirely foolproof in this regard. - It can be host powered when connected via microUSB - It can be self-powered and host an device on microUSB - It can be self-powered and serve as a peripheral if you modify a cable (cut VBUS) or the host is expecting this and has some VBUS detection logic (most hosts will not have this) I just didn't want to encourage use as a peripheral, because it's not very foolproof. But I guess, DTS file will not stop anyone anyway. I'll change it to otg, and maybe leave a small note. regards, o. > Maxime > > -- > Maxime Ripard, Bootlin > Embedded Linux and Kernel engineering > https://bootlin.com

I guess making a comment explaining what you just did would be better though, so that no one is confused. Maxime -- Maxime Ripard, Bootlin Embedded Linux and Kernel engineering https://bootlin.com
