Subject: [PATCH v7 13/15] wifi: ath12k: Switch to generic PAS TZ APIs

From: Sumit Garg <[email-masked]>
Date: Fri, 22 May 2026 17:29:34 +0530

From: Sumit Garg <[email-masked]>

Switch ath12k 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.
