[PATCH AUTOSEL 4.4 02/48] ARM: dts: omap5: enable OTG role for DWC3 controller

[PATCH AUTOSEL 4.4 02/48] ARM: dts: omap5: enable OTG role for DWC3 controller

[Sasha Levin]

From: "H. Nikolaus Schaller" <hns@goldelico.com>

[ Upstream commit 656c1a65ab555ee5c7cd0d6aee8ab82ca3c1795f ]

Since SMPS10 and OTG cable detection extcon are described here, and
work to enable OTG power when an OTG cable is plugged in, we can
define OTG mode in the controller (which is disabled by default in
omap5.dtsi).

Tested on OMAP5EVM and Pyra.

[PATCH AUTOSEL 4.4 48/48] ARM: dts: omap5: Fix dual-role mode on Super-Speed port

[Sasha Levin]

From: Roger Quadros <rogerq@ti.com>

[ Upstream commit a763ecc15d0e37c3a15ff6825183061209832685 ]

OMAP5's Super-Speed USB port has a software mailbox register
that needs to be fed with VBUS and ID events from an external
VBUS/ID comparator.

Without this, Host role will not work correctly.
