… DSI input ports The Lontium LT9211 is capable of 1..4 DSI lanes per input DSI port, describe the lane count for each input port in the schema. For example Linux kernel driver does already use that information and fails to probe if it is missing.

The QCS6490 RB3 Gen2 industrial mezzanine supports LVDS display output using the Lontium LT9211C DSI-to-LVDS bridge as an alternative to the default HDMI output via the LT9611UXC bridge. Add a DTBO overlay, qcs6490-rb3gen2-industrial-mezzanine-lvds-boe,dv215fhm-r01.dtso, that disables HDMI (hdmi-connector and lt9611_codec) and wires up the LT9211C bridge on I2C1 (address 0x29) with reset on GPIO117. The overlay adds a dual-channel panel-lvds node for the boe,dv215fhm-r01 panel, matched against the panel-simple-lvds-dual-ports binding which supplies the panel's size and timing internally. The overlay is built as a composite DTB combining the base qcs6490-rb3gen2.dtb, the industrial mezzanine overlay, and this LVDS overlay.

overlay The Monaco-EVK mezzanine supports LVDS display output using the Lontium LT9211C DSI-to-LVDS bridge. The bridge is connected to the DSI0 output and drives a dual-channel 1920x1080 LVDS panel in VESA-24 mapping. Add a DTBO overlay, monaco-evk-lvds-boe,dv215fhm-r01.dtso, that wires up the LT9211C bridge on I2C8 (address 0x2d) with reset on GPIO66, a panel-lvds node for the boe,dv215fhm-r01 panel (matched against the panel-simple-lvds-dual-ports binding, which supplies the panel's size and timing internally), and an LCD display bias regulator supplied through the GPIO expander. DSI power is provided by vreg_l5a. The overlay is built as a composite DTB combining the base monaco-evk.dtb, the IFP mezzanine overlay, and this LVDS overlay.

quic-vishsain still see dtb-check failed : New composite DTB targets expose schema failures in inherited base/mezzanine nodes |
These errors seems to be pre-existing, not related to this PR. |
