Subject: [PATCH v5 2/6] dt-bindings: phy: renesas,usb2-phy: Document RZ/G2L phy bindings
Date: Tue, 27 Jul 2021 19:55:23 +0100	[thread overview]
Message-ID: <20210727185527.19907-3-biju.das.jz@bp.renesas.com> (raw)
In-Reply-To: <20210727185527.19907-1-biju.das.jz@bp.renesas.com>

Document USB phy bindings for RZ/G2L SoC.

RZ/G2L USB2.0 phy uses line ctrl register for OTG_ID pin changes. It uses
a different OTG-BC interrupt bit for device recognition. Apart from this,
the PHY reset is controlled by USBPHY control IP and Document reset is a
required property.

v4->v5:
 * Removed 'properties' and just used 'required' for RZ/G2L SoC.
v3->v4:
 * Removed second reset
 * Added family specific compatible string.
v2->v3
 * Created a new compatible for RZ/G2L as per Geert's suggestion.
 * Added resets required properties for RZ/G2L SoC.
