arm64: dts: qcom: Add dual-channel LVDS support on QCS615 Talos EVK

[PATCH v1 0/1] arm64: dts: qcom: Add dual-channel LVDS support on QCS615 Talos EVK

Posted by Sudarshan Shetty 3 months, 1 week ago

Hi all,

This patch introduces a new device tree for the QCS615 Talos EVK platform
with dual-channel LVDS display support.

The new DTS file (`talos-evk-lvds.dts`) is based on the existing
`talos-evk.dts` and extends it to enable a dual-channel LVDS display
configuration using the TI SN65DSI84 DSI-to-LVDS bridge.

In this setup:
- LVDS Channel A carries odd pixels.
- LVDS Channel B carries even pixels.

This patch only adds the new DTS and corresponding Makefile entry.

Thanks,
Sudarshan

"This patch"? There shouldn't be a need for a cover letter for a single
patch, the patch commit message should describe itself; as any
information in the cover-letter is lost in the mail archive when the
patch is merged.


Also, please transition to b4, per our internal guidelines.
