[PATCH 3/3] ARM: dts: dra7: workaround silicon limitation i845

From: Roger Quadros <hidden>
Date: 2016-08-23 08:58:18
Also in: linux-omap, lkml
Subsystem: the rest · Maintainer: Linus Torvalds

From: Sekhar Nori <redacted>

Silicon limitation i845 documents how to cope with false
disconnection condition on USB2 PHY. Reference: AM572x
silicon errata document SPRZ429H, revised January 2016.

Using compatible "ti,dra7x-usb2" enables the recommended
software workaround for this issue. Use it for USB1 PHY.

The workaround is already in place for USB2 PHY.
