The display card for the Qualcomm SM8450 HDK board carries an LCD panel module based on the Novatek NT36672E display driver IC. Unlike the panel module, which is supported by the NT36672E panel driver on the QCM6490 IDP board, the display card panel is connected over 3 MIPI C-PHY trios, has a resolution of 1080x2400, and it runs at 144Hz with Display Stream Compression, therefore a new panel configuration sequence is needed. Since MIPI PHY type of the DSI link is fixed by the panel module design, the driver selects the panel description by the PHY type of the DSI link. The initialization sequence, the display timings and the DSC parameters of the display card panel are taken from the Qualcomm display device tree source for the panel: https://git.codelinaro.org/clo/la/platform/vendor/opensource/display-devicetree tag DISPLAY.LA.6.0.r12-02500-WAIPIO.QSSI17.0 display/dsi-panel-nt36672e-fhd-plus-144hz-video-cphy.dtsi The integrated touchscreen controller of the display card is not described, since there is no binding or driver support for it yet.
