From da0b7c7766ea96d057094ecd05bcc1b3fec7e538 Mon Sep 17 00:00:00 2001 From: Badhri Jagan Sridharan Date: Mon, 1 Oct 2018 12:44:59 -0700 Subject: dt-bindings: connector: Add self-powered property >From USB_PD_R3_0 7.1.5 Response to Hard Resets Device operation during and after a Hard Reset is defined as follows: Self-powered devices Should Not disconnect from USB during a Hard Reset (see Section 9.1.2). Bus powered devices will disconnect from USB during a Hard Reset due to the loss of their power source. Therefore it is necessary to know whether the port belongs to a device which is self powered or bus powered. This change adds "self-powered" flag to the connector class which present indicates that the port belongs to a device that is self powered. Else it is bus powered usb device.
