Subject: [PATCH v7 06/15] remoteproc: qcom_q6v5_mss: Switch to generic PAS TZ APIs

From: Sumit Garg <[email-masked]>
Date: Fri, 22 May 2026 17:29:27 +0530

From: Sumit Garg <[email-masked]>

Switch qcom_q6v5_mss client driver over to generic PAS TZ APIs. Generic PAS
TZ service allows to support multiple TZ implementation backends like QTEE
based SCM PAS service, OP-TEE based PAS service and any further future TZ
backend service.
