[PATCH v2 1/3] dt-bindings: remoteproc: qcom,sm8550-pas: Add Hawi and Maili MPSS as SM8650 fallback
From: Mukesh Ojha
Date: Wed Aug 05 2026 - 09:47:56 EST
The Hawi and Maili MPSS blocks are fully compatible with the SM8650 MPSS
with identical interrupt, memory-region, and power-domain topologies, so
they should ideally fall back to the SM8650 compatible.
Introduce a fallback items block that pairs qcom,hawi-mpss-pas and
qcom,maili-mpss-pas with qcom,sm8650-mpss-pas. Switch the mpss
memory-region and power-domain allOf blocks from enum: to contains: so the
constraints apply whether the compatible appears in the standalone form or
as part of a fallback array.
