Subject: [PATCH 08/14] remoteproc: qcom_wcnss: Switch to generic PAS TZ APIs

From: Sumit Garg <[email-masked]>
Date: Fri, 6 Mar 2026 16:20:21 +0530

From: Sumit Garg <[email-masked]>

Switch qcom_wcnss 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.
