[PATCH v3 00/13] PHY: Add support for multilink configurations in Cadence Torrent PHY driver

From: Swapnil Jakhade
Date: Thu Sep 17 2020 - 03:50:26 EST


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 should be applied on
top of this.
