Hi all,

This patch series adds device tree binding and board support for the
Qualcomm Technologies, Inc. Talos EVK SMARC platform based on the
QCS615 SoC.

The first patch introduces the DT binding entry for the Talos EVK
SMARC board, and the second patch adds the corresponding DTS
files for the platform.

Note:
USB(usb_1_dwc3) supports host-only mode based on the switch SW1 on
the SoM, which is purely a hardware controlled as USB-ID and USB-VBUS
is not connected the switching cannot be handled from SW.
Hence from SW Host-only mode is supported on Linux boot up.

Changes in v5:
 - Updated commit message. (suggested by Krzysztof)
 - Introduced generic node name for can, dp, hdmi-bridge. (suggested by
   Krzysztof)
 - Introduced talos-evk-cb.dtsi, which has common carrier board
   interfaces.
 - No functional change in bindings file.

Changes in v4:
 - Updated product name to full form per Krzysztof’s feedback in
   dt-binding comment.
 - Hook up the ADV7535 DSI-to-HDMI bridge to base DTS file.
 - Add DP connector node and MDSS DisplayPort controller.
 - Added USB note in the cover letter for maintainers' awareness.

Changes in v3:
 - Addressed comments from Dmitry regarding USB1 `dr_mode` and 
   added a DTS comment.
 - No functional change in bindings file.

Changes in v2:
 - Renamed compatible to "qcom,talos-evk" (suggested by Dmitry/Bjorn)
 - Merged enum entry with existing `qcs615-ride` block (Krzysztof)
 - Fixed subject and commit message to use imperative mood.

Thanks,
Sudarshan

Introduced talos-evk-cb.dtsi to define carrier board–specific interfaces
common to both HDMI and LVDS top-level DTS variants.

Are those two different carrier boards? Is it a single carrier board
with mezzanines? With extension boards? With a DIP switch?

It’s a single carrier board.
HDMI and LVDS share the same DSI interface, and only one can be active at
a time depending on a DIP switch.

Thank you for describing this in the cover letter and in the commit
message in the nextt revision.
