[PATCH RFC 0/2] usb: typec: Add new driver for Parade PS8830 Type-C Retimer

[Abel Vesa]

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.
