[PATCH v2 2/6] dt-bindings: media: qcom,glymur-camss: Add Glymur CAMSS
From: Nihal Kumar Gupta
Date: Mon Sep 07 2026 - 04:15:30 EST
X1E80100 supports both the legacy CSIPHY resources and the new PHY API;
Glymur uses only the new PHY API via standalone phy@ child nodes,
so per-CSIPHY clocks, interrupts and supplies are absent here.
X1E80100 has four CSIPHY instances while Glymur has three
(CSIPHY0, CSIPHY1, CSIPHY4), expressed entirely in DT.
