Cadence Torrent PHY is a multiprotocol PHY supporting different multilink PHY configurations including DisplayPort, PCIe, USB, SGMII, QSGMII etc. Existing Torrent PHY driver supports only DisplayPort. This patch series prepares Torrent PHY driver so that different multilink configurations can be supported. It also updates DT bindings accordingly. This doesn't affect ABI as Torrent PHY driver has never been functional, and therefore do not exist in any active use case.
Support for different multilink configurations with register sequences for protocols above will be added in a separate patch series. This patch series is dependent on PHY attributes patch series [1].
