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@oss.qualcomm.com/ 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@oss.qualcomm.com/ which documents the boe,dv215fhm-r01 panel and add timings used by these overlays. Signed-off-by: Vishnu Saini --- Changes in v2: - Updated overlays to make them compatable with panel-simple-lvds-dual-ports.yaml [Rob (in panel series)] - Added Empty lines before the status property [Dmitry] - Link to v1: https://lore.kernel.org/r/20260719-lvds-support-v1-0-1f1aca3213ba@oss.qualcomm.com --- Vishnu Saini (3): arm64: dts: qcom: lemans-evk: Add LVDS display overlay arm64: dts: qcom: monaco-evk: Add LVDS display overlay arm64: dts: qcom: qcs6490-rb3gen2: Add LVDS display overlay arch/arm64/boot/dts/qcom/Makefile | 14 +++ .../dts/qcom/lemans-evk-lvds-boe,dv215fhm-r01.dtso | 116 ++++++++++++++++++++ .../dts/qcom/monaco-evk-lvds-boe,dv215fhm-r01.dtso | 117 +++++++++++++++++++++ ...industrial-mezzanine-lvds-boe,dv215fhm-r01.dtso | 105 ++++++++++++++++++ 4 files changed, 352 insertions(+) --- base-commit: f86573e68e56a7df7d54eb58101ac413ba731996 change-id: 20260708-lvds-support-2d40d60654f1 prerequisite-message-id: <20260719-add-lt9211c-bridge-v6-0-e56d22152586@oss.qualcomm.com> prerequisite-patch-id: dbba64d1ace696df388c5df3d1cb05a0701df194 prerequisite-patch-id: 7729b9c67a7c274b25fea08635dfede3fc604ae9 prerequisite-message-id: <20260810-b4-lvds-panel-doc-v2-0-f2c2fe309989@oss.qualcomm.com> prerequisite-patch-id: bd3612ce053552e2ae7401a1217c4884413563f4 prerequisite-patch-id: 1d3e40bbefcb2550afd81c5cced812a1d3b943a2 Best regards, -- Vishnu Saini
