This series adds LVDS display support via device tree overlays for three
Qualcomm platforms: Lemans EVK, 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 are structured to be applied on top of the existing IFP
mezzanine overlay.

This series depends on:
  [PATCH v8 0/2] This series adds LT9211C bridge driver by extending LT9211
  https://lore.kernel.org/all/20260904-add-lt9211c-bridge-v8-0-36d66168e176@oss.qualcomm.com/

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

  [PATCH v4 0/2] This series adds BOE DV215FHM-R01 LVDS panel support
  https://lore.kernel.org/all/20260903-b4-lvds-panel-doc-v4-0-861738a0d5de@oss.qualcomm.com/

which documents the boe,dv215fhm-r01 panel and adds the timings used by these
overlays, and:

  arm64: defconfig: Enable Lontium LT9211 driver
  https://lore.kernel.org/all/20260904-for-next-lt9211-defconfig-v1-1-97221f0109d7@oss.qualcomm.com/

which enables the driver in defconfig.

Then get those merge first, so that I don't have to spend time figuring
that out for you.

This is not a dependency for your changes to be merged.

Thank you, next revision will be posted once dependencies are applied.
