Subject: [PATCH v3 1/3] dt-bindings: connector: Add self-powered property
Date: Mon, 1 Oct 2018 12:44:59 -0700 [thread overview]
Message-ID: <20181001194501.58338-1-badhri@google.com> (raw)
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.

- Rebase on top of usb-next
- no change w.r.t to this patch. Same as previous versions.
No v2 version as the patch was introduced there.
