Subject: dt-bindings: phy: ti,phy-usb3: convert to DT schema
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=62c9ff8fc20d23c0dc36be1330734fdafb3e8585;p=thirdparty%2Flinux.git

dt-bindings: phy: ti,phy-usb3: convert to DT schema

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.
