Subject: [PATCH 0/3] Add the support of SVDM Version 2.0 VDOs

Hi Greg, these patches are based on usb-linus branch. Is it okay?

===

The patches are primarily for the responses to the Discover Identity
command. This part was changed a lot from PD rev2.0 to PD rev3.0 (now
it's rev3.1 :D). e.g. DFP can respond to Discover Identity command with
ACK in PD rev3.x and the Product Type VDOs are quite different. Given
that tcpm.c moved on to PD rev3.x and PD rev2.0 is still supported, some
changes need to be made to support both PD rev3.x and rev2.0.

usb: typec: tcpm: Correct the responses in SVDM Version 2.0 DFP
- This patch is to unblock the responder ACK to Discover Identity if the
  port is DFP and the SVDM version is 2.0

dt-bindings: connector: Add PD rev 2.0 VDO definition
- similar changes to Commit 2a1673f0f1de ("usb: pd: Reland VDO
  definitions of PD2.0")
  https://lore.kernel.org/linux-usb/20210204005036.1555294-1-kyletso@google.com/
- add a new property sink-vdos-v1 to store the PD rev2.0 VDOs

usb: typec: tcpm: Introduce snk_vdo_v1 for SVDM version 1.0
- populate the legacy VDOs from fwnode
- send these data if the port partner is SVDM Version 1.0
