Pull remoteproc updates from Bjorn Andersson: - Move requesting of IRQs in TI Keystone driver to probe time instead of remoteproc start, to allow better handling of errors. - Introduce support for more than 10 entries in the Qualcomm minidump implementation. - Add audio DSP remoteproc support for the Qualcomm Eliza platform. Add modem remoteproc support for the Qualcomm MDM9607, MSM8917, MSM8937, and MSM8940 platforms. - Add list of Qualcomm QMI service ids to the QMI header file, in order to avoid sprinkling them across the various drivers using them. Migrate sysmon to use this constant. - Fix several issues related to DeviceTree parsing and mailbox handling in the Xilinx R5F remote processor driver. - Fix incorrect error checks in reserved memory handling and polish the code across i.MX and TI drivers. * tag 'rproc-v7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux: (35 commits) remoteproc: qcom: pas: Add Eliza ADSP support dt-bindings: remoteproc: qcom,milos-pas: Document Eliza ADSP remoteproc: qcom: Add missing space before closing bracket dt-bindings: remoteproc: qcom: Drop types for firmware-name remoteproc: qcom: Fix minidump out-of-bounds access on subsystems array dt-bindings: remoteproc: k3-r5f: Add memory-region-names dt-bindings: remoteproc: k3-r5f: Split up memory regions remoteproc: use SIZE_MAX in rproc_u64_fit_in_size_t() dt-bindings: remoteproc: qcom,sm8550-pas: Add Glymur CDSP dt-bindings: remoteproc: qcom,sm8550-pas: Add Glymur ADSP remoteproc: xlnx: Release mailbox channels on shutdown remoteproc: sysmon: Use the unified QMI service ID instead of defining it locally remoteproc: xlnx: Only access buffer information if IPI is buffered remoteproc: xlnx: Avoid mailbox setup remoteproc: keystone: Request IRQs in probe() remoteproc: pru: Remove empty remove callback remoteproc: pru: Use rproc_of_parse_firmware() to get firmware name remoteproc: da8xx: Reorder resource fetching in probe() remoteproc: da8xx: Remove unused local struct data remoteproc: da8xx: Use dev_err_probe() ...

remoteproc: qcom: pas: Add Eliza ADSP support

2026-04-06T14:49:21Z

The ADSP found on Eliza SoC is similar to the one found on SM8550. So just add the dedicated compatible for Eliza ADSP and reuse the SM8550 resource configuration.

remoteproc: qcom: Add missing space before closing bracket

2026-04-06T14:48:05Z

Add missing space before closing curly bracket for qcom_q6v5_mss and qcom_q6v5_pas driver of_match[] lines, so that all qcom remoteproc drivers are consistent on the common coding style.

remoteproc: qcom: Fix minidump out-of-bounds access on subsystems array

2026-04-06T14:44:12Z

MAX_NUM_OF_SS was hardcoded to 10 in the minidump_global_toc struct, which is a direct overlay on an SMEM item allocated by the firmware. Newer Qualcomm SoC firmware allocates space for more subsystems, while older firmware only allocates space for 10. Bumping the constant would cause Linux to read/write beyond the SMEM item boundary on older platforms. Fix this by converting subsystems[] to a flexible array member and deriving the actual number of subsystems at runtime from the size returned by qcom_smem_get(). Add a bounds check on minidump_id against the derived count before indexing into the array.

remoteproc: mtk_scp: Constify buffer passed to scp_send_ipi()

scp_send_ipi() should only send the passed buffer, without modifying its contents, so mark pointer 'buf' as pointer to const.

remoteproc: use SIZE_MAX in rproc_u64_fit_in_size_t()

2026-03-24T16:33:29Z

Smatch reports: drivers/remoteproc/remoteproc_elf_loader.c:221 warn: always true condition '(val <= -1)' The helper function rproc_u64_fit_in_size_t() compares the value against (size_t)-1, which is equivalent to SIZE_MAX but can confuse static analysis tools and lead to the above warning. Replace (size_t)-1 with SIZE_MAX to make the intent explicit and avoid the Smatch warning without changing the behavior.

remoteproc: xlnx: Release mailbox channels on shutdown

2026-03-17T15:48:55Z

Mailbox driver can't introduce shutdown callback, as it might endup closing mbox channels prematurely. By allowing the client driver to manage the shutdown process, it's ensured that mailbox channels are closed only when they are no longer needed.

Instead of defining a local macro with a custom name for the QMI service identifier, use the one provided in qmi.h and remove the locally defined macro.
