[PATCH v2 13/15] wifi: ath12k: Switch to generic PAS TZ APIs

From: Sumit Garg

Date: Thu Mar 12 2026 - 02:33:02 EST


From: Sumit Garg <sumit.garg@xxxxxxxxxxxxxxxx>

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.
