dt-bindings: display: msm: Fix reg ranges and clocks on Glymur

2026-03-19T15:15:26Z

commit 7403e87c138475a74e5176176778f391d847f42d upstream. The Glymur platform has four DisplayPort controllers. The hardware supports four streams (MST) per controller. However, on Glymur the first three controllers only have two streams wired to the display subsystem, while the fourth controller operates in single-stream mode. Add a dedicated clause for the Glymur compatible to require the register ranges for all four stream blocks, while allowing either one pixel clock (for the single-stream controller) or two pixel clocks (for the remaining controllers). Update the Glymur MDSS schema example by adding the missing p2, p3, mst2link and mst3link register blocks. Without these, the bindings validation fails. Also replace the made-up register addresses with the actual addresses from the first controller to match the SoC devicetree description.
