[PATCH v2 0/3] arm64: dts: qcom: Add LVDS display overlays for lemans, monaco and rb3gen2

[Vishnu Saini]

This series adds LVDS display support via device tree overlays for three
Qualcomm platforms: SA8775P Lemans EVK, SA8295P/QCS8300 Monaco EVK, and
QCS6490 RB3 Gen2 industrial mezzanine.

All three platforms use the Lontium LT9211C DSI-to-LVDS bridge chip, which
converts DSI output to dual-channel LVDS for driving 1920x1080 panels.
The overlays follow the established composite-DTB pattern already in use
on these platforms (IFP mezzanine, camera, el2) and are structured to be
applied on top of the existing IFP mezzanine overlay.

Each overlay:
  - Wires the LT9211C bridge to the DSI output via an I2C node
  - Defines a generic dual-channel panel-lvds node with VESA-24 mapping
    targeting a 1920x1080 (476x268mm) panel at 148.5 MHz pixel clock
  - Provides an LCD bias regulator through the GPIO expander

This series depends on:
  [PATCH v6 0/2] This series adds LT9211C bridge driver by extending LT9211
  https://lore.kernel.org/all/20260719-add-lt9211c-bridge-v6-0-e56d22152586@xxxxxxxxxxxxxxxx/

which adds lontium,lt9211c compatible support to the lontium-lt9211 driver
and extends the binding YAML accordingly, and:

  [PATCH v2 0/2] This series adds BOE DV215FHM-R01 LVDS panel support
  https://lore.kernel.org/all/20260810-b4-lvds-panel-doc-v2-0-f2c2fe309989@xxxxxxxxxxxxxxxx/

which documents the boe,dv215fhm-r01 panel and add timings used by these overlays.
