The Parade PS8830 is a Type-C multi-protocol retimer that is controlled via I2C. It provides altmode and orientation handling and usually sits between the Type-C port and the PHY. It is currently used alongside Qualcomm Snapdragon X Elite SoCs on quite a few laptops already. This new driver adds support for the following 3 modes: - DP 4lanes - with pin assignments C and E - USB3 - DP 2lanes + USB3 Only DP 4lanes and USB3 modes have been succesfully tested on Qualcomm (X Elite) CRD and Lenovo Thinkpad T14s so fat. Devicetree patches for these 2 boards will follow. The DP 2lanes + USB3 is still work-in-progress as it might involve changes outside of this retimer driver.
