Subject: [PATCH v2 01/14] dt-bindings: usb: amlogic,meson-g12a-usb-ctrl: add the Amlogic GXL and GXM Families USB Glue Bindings
Date: Thu, 26 Mar 2020 14:44:53 +0100
Message-ID: <20200326134507.4808-2-narmstrong@baylibre.com> (raw)
In-Reply-To: <20200326134507.4808-1-narmstrong@baylibre.com>

The Amlogic GXL and GXM is slightly different from the Amlogic G12A Glue.

The GXL SoCs only embeds 2 USB2 PHYs and no USB3 PHYs, and the GXM SoCs
embeds 3 USB2 PHYs.
