Cadence Torrent PHY is a multiprotocol PHY supporting different multilink
PHY configurations including DisplayPort, PCIe, USB, SGMII, QSGMII etc.
This patch series extends functionality of Torrent PHY driver to support
following configurations:
- Single link PCIe configuration
- PCIe + SGMII/QSGMII Unique SSC multilink configuration
- Single link SGMII/QSGMII configuration
- Single link USB configuration
- PCIe + USB Unique SSC multilink configuration
- USB + SGMII/QSGMII multilink configuration

The changes have been validated on TI J7200 platform.

This patch series is dependent on [1] and [2] and should be applied on
top of these.
