[PATCH v2 10/15] drm/msm: Switch to generic PAS TZ APIs
From: Sumit Garg <sumit.garg@kernel.org>
Date: 2026-03-12 06:31:03
Also in:
ath12k, dri-devel, linux-arm-msm, linux-devicetree, linux-media, linux-remoteproc, linux-wireless, lkml, op-tee
Subsystem:
drm driver for qualcomm adreno gpus, drm driver for qualcomm display hardware, drm drivers, the rest · Maintainers:
Rob Clark, Dmitry Baryshkov, David Airlie, Simona Vetter, Linus Torvalds
From: Sumit Garg <redacted> Switch drm/msm client drivers 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.
