Subject: [PATCH v3 2/3] dt-bindings: phy: ti,phy-usb3: convert to DT schema
Date: Thu, 22 Jan 2026 17:52:58 +0000	[thread overview]
Message-ID: <20260122-ti-phy-v3-2-751619729433@gmail.com> (raw)
In-Reply-To: <20260122-ti-phy-v3-0-751619729433@gmail.com>

Convert TI PIPE3 PHY binding to DT schema.
Changes during conversion:
- Define a new pattern 'pcie-phy' to match nodes defined in DT.
- Drop obsolete "id" property from the schema.

+description:
+  The TI PIPE3 PHY is a high-speed SerDes (Serializer/Deserializer)
+  transceiver integrated in OMAP5, DRA7xx/AM57xx, and similar SoCs.
+  It supports multiple protocols (USB3, SATA, PCIe) using the PIPE3
+  interface standard, which defines a common physical layer for
+  high-speed serial interfaces.
