[PATCH v5 0/2] Add Qualcomm Technologies, Inc. Talos EVK SMARC support

[Sudarshan Shetty]

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

[PATCH v5 2/2] arm64: dts: qcom: talos-evk: Add support for QCS615 talos evk board

[Sudarshan Shetty]

Introduce the device tree support for the QCS615-based talos-evk
platform, which follows the SMARC (Smart Mobility ARChitecture)
standard. The platform is composed of two main hardware
components: the talos-evk-som and the talos-evk carrier board.

The initial device tree includes basic support for:
- CPU and memory
- UART
- GPIOs
- Regulators
- PMIC
- Early console
- AT24MAC602 EEPROM
- MCP2515 SPI to CAN
- ADV7535 DSI-to-HDMI bridge
- DisplayPort

How is the carrier board a separate entity from the "talos-evk.dts"?

The talos-evk platform follows a modular SoM + carrier design.
In our current implementation:
talos-evk-som.dtsi — describes SoM-specific components.
talos-evk-cb.dtsi — represents the carrier board and includes the
SoM file, adding carrier-specific interfaces (micro SD, power button etc.).
talos-evk.dts — includes both the SoM and CB DTSIs and enables HDMI 
display configuration.
talos-evk-lvds.dts — also includes both the SoM and CB DTSIs but enables 
LVDS instead of HDMI.

HDMI and LVDS share the same DSI output and cannot be used simultaneously.
Therefore, we provide separate top-level DTS files (talos-evk.dts for HDMI
and talos-evk-lvds.dts for LVDS), while keeping common board
logic in talos-evk-cb.dtsi.

Hence, layer looks as below:

talos-evk-som.dtsi
├── talos-evk-cb.dtsi (includes som)
│    ├── talos-evk.dts (HDMI)
│    └── talos-evk-lvds.dts (LVDS)

This ensures modularity, and properly models mutually exclusive display
configurations.

And are both the LVDS display and HDMI converter on separate add-in boards?

Both HDMI and LVDS interfaces are present on the same carrier board, 
but they share the same DSI output from the SoM.

The hardware requires physical reconfiguration (resistor changes)
to select either the ADV7535 HDMI path or the LVDS bridge path.

Because they cannot be used simultaneously and represent different hardware
configurations, we provide two separate DTS files — one for HDMI and 
one for LVDS — while keeping the common carrier definitions in talos-evk-cb.dtsi.

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.
