Introduce a generic Qualcomm PAS service with SCM and OP-TEE backends, and migrate the PAS, MSS, and WCNSS remoteproc drivers to it. Add Nord ADSP and CDSP support, Eliza CDSP support, Maili ADSP/CDSP bindings, and late-attach SoCCP support for Kaanapali, Hawi, Maili, and Glymur. Enable BAM-DMUX child devices for PAS modems and fix PAS memory protection, handover, shutdown, and resource lifetime handling. Harden remoteproc lifecycle handling by attaching asynchronously, stopping crashed processors, synchronizing crash work with removal, and forcing shutdown before device resources are released. Reallocate resources during attach recovery and fix several reference and error-path leaks. Add Xilinx R5 crash detection and move RPU start and stop sequencing into the platform firmware driver. Consolidate write-combining carveout mapping callbacks, use correct I/O-memory accessors, and share optional ELF resource-table handling across drivers. Convert the TI Wakeup M3 binding to DT schema, correct Qualcomm and generic remoteproc bindings, and harden resource-table iteration against signed-offset out-of-bounds accesses" * tag 'rproc-v7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux: (60 commits) remoteproc: fix OOB read via signed offset in rsc_table_for_each_entry() remoteproc: replace BSD blurb with SPDX identifier in rsc_table.h remoteproc: replace BSD blurb with SPDX identifier in remoteproc.h remoteproc: fix coding style issues in remoteproc.h MAINTAINERS: add rsc_table.h to remoteproc entry remoteproc: qcom: pas: Add Nord ADSP and CDSP support dt-bindings: remoteproc: qcom,nord-pas: Document Nord PAS remoteproc: qcom: pas: Drop unused dtb_mem_region field remoteproc: qcom: pas: Map/unmap subsystem region before auth_and_reset remoteproc: qcom: pas: Fix the PAS context creation placement remoteproc: qcom: pas: Guard dtb metadata release with dtb_pas_id check remoteproc: qcom: annotate mem_region fields with __iomem arm64: dts: qcom: eliza: Add fallback compatible for ADSP remoteproc dt-bindings: remoteproc: qcom,milos-pas: Move Eliza ADSP to SM8550 schema remoteproc: qcom: pas: Add Eliza CDSP support dt-bindings: remoteproc: qcom,sm8550-pas: Add Eliza CDSP compatible remoteproc: qcom: q6v5: Request shutdown if crash is triggered host-side remoteproc: Force shutdown during device removal remoteproc: Prevent crash handling to race with rproc_del() remoteproc: Allow shutdown of crashed processors ... 2026-08-21T18:58:08+00:00 Linus Torvalds torvalds@linux-foundation.org 2026-08-21T18:58:08+00:00 urn:sha1:f96718fc1f6142038a3f836b83b12e5062576a2f Pull MMC updates from Ulf Hansson: "MMC core: - Reject invalid perdev_minors for the block device before division - Document DT fixed-layout NVMEM provider support for eMMC cards MMC host: - Convert a couple of plain text DT bindings to the yaml format - bcm2835: DMA mapping improvements - cqhci: Fix sparse warnings for endian conversions - dw_mmc: Stop and complete DMA also in busy state - dw_mmc-rockchip: Add support for the RV1106 variant - litex_mmc: Add dynamic bus width support - moxart: Propagate error for DMA completion timeout - pxamci: Remove PXA remnants for the PXA93x support - rtsx_usb_sdmmc: Avoid USB I/O in runtime autosuspend - rtsx_usb_sdmmc: Suppress false CD after init timeout - sdhci_am654: Add Judith Mendez as maintainer - sdhci-esdhc-mcf: Do not use readl()/writel() on ColdFire - sdhci-msm: Extend the DT bindings for ICE - sdhci-tegra: Add support for Tegra264/Tegra238 variants - sunxi: Add support for the Allwinner A733 variant - via-sdmmc: Clean up card detect work at remove and in probe error path" * tag 'mmc-v7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc: (35 commits) ARM: PXA: Fix build error for PXA93x dt-bindings: mmc: sunxi: add compatible string for Allwinner A733 MMC0/1/2 dt-bindings: mmc: Document fixed-layout NVMEM provider support mmc: sdhci-tegra: Add Tegra264 SoC data dt-bindings: mmc: tegra: Document Tegra264 SDHCI mmc: sdhci-tegra: Add Tegra238 SoC data dt-bindings: mmc: tegra: Document Tegra238 SDHCI mmc: omap_hsmmc: use platform_get_irq_optional for wake IRQ mmc: via-sdmmc: cancel card-detect work on remove mmc: via-sdmmc: stop card-detect handling on probe failure mmc: moxart: use platform helpers for resource and IRQ mmc: host: Remove redundant dev_err()/dev_err_probe() mmc: bcm2835: DMA mapping improvements mmc: dw_mmc: move declaration of dw_mci_pmops dt-bindings: mmc: rockchip-dw-mshc: Add RV1106 compatible mmc: rtsx_usb_sdmmc: suppress false CD after init timeout misc: rtsx_usb: avoid USB I/O in runtime autosuspend mmc: sdhci-of-dwcmshc: Log eMMC reset calls mmc: block: reject invalid perdev_minors before division mmc: sdhci-of-ma35d1: add missing MODULE_DEVICE_TABLE() ... 2026-08-19T16:47:41+00:00 Linus Torvalds torvalds@linux-foundation.org 2026-08-19T16:47:41+00:00 urn:sha1:307b9ddbbcf987db77d52da6f9ff5b4096ac9599 Pull spi updates from Mark Brown: "Along with a lot of driver specific work we've got a couple of core features here.

This behavior was introduced to avoid issues seen in the past where speculative accesses from the application processor to the MBA region after it was assigned to the remote Q6 led to an XPU violation. The issue was mitigated by unmapping the region before handing control to the remote Q6. Currently, most Qualcomm SoCs using the PAS driver run either with a standalone QHEE or the Gunyah hypervisor. In these environments, the hypervisor unmaps the Q6 memory from HLOS Stage-2 and remaps it into the Q6 Stage-2 page table. As a result, speculative accesses from HLOS cannot reach the region even if it remains mapped in HLOS Stage-1; therefore, XPU violations cannot occur. However, when the same SoC runs Linux at EL2, Linux itself must perform the unmapping to avoid such issues. It is still correct to apply this mapping/ unmapping sequence even for SoCs that run under Gunyah, so this behavior should not be conditional. Introduce qcom_pas_ctx_map() in qcom_pas.h to centralise the ioremap_wc pattern used by both qcom_q6v5_pas and qcom_mdt_pas_load, and use it in both places.

Add support for parsing v3-v7 version of the structs. Unforunately, they are not versioned, so some elbow grease is necessary to determine which one is present.
