Subject: [PATCH v2 15/16] dt-bindings: soc: socionext: Add UniPhier DWC3 USB glue layer
Date: Wed, 7 Dec 2022 14:54:04 +0900 [thread overview]
Message-ID: <20221207055405.30940-16-hayashi.kunihiko@socionext.com> (raw)
In-Reply-To: <20221207055405.30940-1-hayashi.kunihiko@socionext.com>
Add DT binding schema for components belonging to the platform-specific
DWC3 USB glue layer implemented in UniPhier SoCs.
This USB glue layer works as a sideband logic for the host controller,
including core reset, vbus control, PHYs, and some signals to the
controller.
