Subject: [PATCH 0/2] USB: dwc3: get extcon device by OF graph bindings
Date: Wed, 31 Jan 2018 16:57:16 +0100	[thread overview]
Message-ID: <20180131155718.5237-1-a.hajda@samsung.com> (raw)

Hi,

This small patchset tries to address issue with broken DT extcon property
in case of USB controller - DWC3. It exposes similar problem as in proposed
USB connector bindings[1] - extcon device is required by devices not always
connected directly to extcon device. Here we have:
DWC3 -> USB-PHY -> MUIC -> USB-connector
                               ^
MHL-bridge---------------------^

More details and proposition of generic solution in first patch

Andrzej
