Subject: [PATCH v3 4/8] dt-bindings: phy: Convert Calxeda ComboPHY binding to json-schema

Convert the Calxeda ComboPHY binding to DT schema format using
json-schema.
There is no driver in the Linux kernel matching the compatible
string, but the nodes are parsed by the SATA driver, which links to them
using its port-phys property.

+title: Calxeda Highbank Combination PHYs binding for SATA
+
+description: |
+  The Calxeda Combination PHYs connect the SoC to the internal fabric
+  and to SATA connectors. The PHYs support multiple protocols (SATA,
+  SGMII, PCIe) and can be assigned to different devices (SATA or XGMAC
+  controller).
+  Programming the PHYs is typically handled by those device drivers,
+  not by a dedicated PHY driver.
