[PATCH v3 1/2] dt-bindings: display: msm: Fix reg ranges and clocks on Glymur
From: Abel Vesa
Date: Mon Mar 02 2026 - 04:59:35 EST
The Glymur platform has four DisplayPort controllers. All the
controllers support four streams (MST). However, the first three only
have two streams wired up physically to the display subsystem, while the
fourth controller has only one stream (SST).
So add a dedicated clause for Glymur compatible to enforce reg ranges to
describing all four streams while allowing either one pixel clock, for the
third DP controller, or two pixel clocks, for the rest of them.
Cc: <stable@xxxxxxxxxxxxxxx> # v6.19
Fixes: 8f63bf908213 ("dt-bindings: display: msm: Document the Glymur DiplayPort controller")
