From 96e47e798cd157d32face71551242d2b6fe42b89 Mon Sep 17 00:00:00 2001 From: Mukesh Ojha Date: Wed, 5 Aug 2026 18:51:28 +0530 Subject: [PATCH] dt-bindings: remoteproc: qcom,sm8550-pas: Make SDX75 MPSS fallback to SM8650 The SDX75 MPSS is an instance of the SM8650 MPSS: same interrupts, memory regions and power domain topology. It is currently modelled as a standalone compatible and lives alongside sm8650 in every mpss allOf conditional, which duplicates the constraint and hides the hardware relationship. Move qcom,sdx75-mpss-pas out of the standalone enum into the fallback items block alongside Hawi and Maili, and drop it from the mpss memory-region and power-domain conditional lists. contains: on the fallback compatible qcom,sm8650-mpss-pas keeps the constraints firing for the array form. Two consequences of the tightening are worth calling out: - qcom,sdx75-mpss-pas as a single-string compatible is no longer valid per the binding, so the in-tree sdx75.dtsi form fails dt_binding_check. That is fixed by the follow-up DTS patch which switches sdx75.dtsi to the fallback array form. - The driver keeps its standalone qcom,sdx75-mpss-pas of_match entry so already-deployed DTBs continue to probe. The binding is intentionally stricter than the driver here; pruning the driver match is left as a separate cleanup once the DTB rollout is complete.
