Subject: [PATCH] arm64: dts: meson-g12a: add missing dwc2 phy-names
Date: Tue, 25 Jun 2019 14:36:47 +0200 [thread overview]
Message-ID: <20190625123647.26117-1-narmstrong@baylibre.com> (raw)
The G12A USB2 OTG capable PHY uses a 8bit large UTMI bus, and the OTG
controller gets the PHY but width by probing the associated phy.
By default it will use 16bit wide settings if a phy is not specified,
in our case we specified the phy, but not the phy-names.
The dwc2 bindings specifies that if phys is present, phy-names shall be
"usb2-phy".
Adding phy-names = "usb2-phy" solves the OTG PHY bus configuration.
Fixes: 9baf7d6be730 ("arm64: dts: meson: g12a: Add G12A USB nodes")
