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 Kyle Tso (3): usb: typec: tcpm: Correct the responses in SVDM Version 2.0 DFP dt-bindings: connector: Add PD rev 2.0 VDO definition usb: typec: tcpm: Introduce snk_vdo_v1 for SVDM version 1.0 .../bindings/connector/usb-connector.yaml | 15 ++++ drivers/usb/typec/tcpm/tcpm.c | 52 ++++++++++---- include/dt-bindings/usb/pd.h | 69 ++++++++++++++++++- 3 files changed, 119 insertions(+), 17 deletions(-)
