This series is a collection of misc fixes for the Qualcomm PAS remoteproc driver and its supporting SCM/MDT loader infrastructure.
- Fix sparse __iomem warnings in qcom_adsp, qcom_pas and qcom_wcnss by annotating mem_region fields with __iomem and using __force at call sites. - Guard the DTB metadata release in qcom_pas_load() with a dtb_pas_id check, consistent with all other release sites in the driver. - Move PAS context allocation from probe into qcom_pas_alloc_memory_region() so the DTB context is only created for subsystems that actually use it. - Map/unmap the subsystem memory region on demand around firmware load and coredump, avoiding potential XPU violations on EL2 platforms where the region may be handed off to the remote side. - Drop the now-unused dtb_mem_region field from struct qcom_pas. - Add a keep_mdt_buf flag to struct qcom_scm_pas_context to make metadata buffer retention explicit rather than implicit. Changes in v4: https://lore.kernel.org/lkml/[email protected]/ https://lore.kernel.org/lkml/[email protected]/ - Last series mistakenly divided two series cause laptop shutdown. - Some minor refactor common code rest is same a rebased on latest kernel. - Added new 6/6 to the series.
