This introduces a range of improvements to the OMAP remoeteproc driver; among other things adding devicetree, suspend/resume and watchdog support, and adds support the remoteprocs in the DRA7xx SoC. It introduces support for 64-bit firmware, extends the ELF loader to support this and fixes for a number of race conditions in the recovery handling. It introduces a generic mechanism to allow remoteproc drivers to sync state with remote processors during a panic, and uses this to prepare Qualcomm remote processors for post mortem analysis. Finally it introduces fixes to cleanly recover from crashes in the modem firmware on production Qualcomm devices. -----BEGIN PGP SIGNATURE----- iQJPBAABCAA5FiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAl6FObEbHGJqb3JuLmFu ZGVyc3NvbkBsaW5hcm8ub3JnAAoJEAsfOT8Nma3FerQP/A4X/ONtMSwfamWseInj TRfYj5BOo6drGKavgG9NjQti2pUDfUo6wen906uRlgE48pEwToCVBZ1ERONj/pPD nsEzXWsZqDjVut9VH5Zhc+T9k+GJVlLkocu+EnpnS9uZ59ySuH/HFY0W6BoyVpuI 2ltodDq9TGHY3nFkaAz+yQKGsqB3e0RqlqCsTHnKHxeOsaG+HLyH89QPUIQzYMAJ P+CyW+h62KnlW7I0nteX3M86nmDxD1S7lQg6NK9GMiuOyVw4FyGiO3+AnX9JBue8 fFF1Z5344WT44IA7n/pjTdKtRy1R8CkwVKBzooWwpvGJo/3d3D1VcYN1S2IoNlb4 L3j3tBSexhthekZ5nBowHdfv5cbTAlWQn8GwKXDRLw4TVrV+wVdeG3kXNbhD6Ka2 sdAv5W4Eguap5dvlJqbC/d6cvQXiZOrzWogd0aqhSB6aMiyb+Pjol+kQZtNWIW1S CmvRFhlSnAwM0NLYQpXGzuaza8LvfMphG6+nwkneSD5IFclKQ+tUxmqOtt2dLqVG 9gtiqSt7fO58I4KxtQGWvp3FBa4FVeH00hF+H0Xu2B9pEsWYr9N2Ua5CDlIJdWKV OS6sVHlYB1a+E4IpJ92GEBp/KwmRJsVCNRKkbDE3Y7UNFoNoTPhnVlsdx5Sa/stT lTQPYoIKmOF8hTZEzLM4Vc7n =5Q77 -----END PGP SIGNATURE----- Merge tag 'rproc-v5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/andersson/remoteproc Pull remoteproc updates from Bjorn Andersson: - a range of improvements to the OMAP remoeteproc driver; among other things adding devicetree, suspend/resume and watchdog support, and adds support the remoteprocs in the DRA7xx SoC - support for 64-bit firmware, extends the ELF loader to support this and fixes for a number of race conditions in the recovery handling - a generic mechanism to allow remoteproc drivers to sync state with remote processors during a panic, and uses this to prepare Qualcomm remote processors for post mortem analysis - fixes to cleanly recover from crashes in the modem firmware on production Qualcomm devices * tag 'rproc-v5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/andersson/remoteproc: (37 commits) remoteproc/omap: Switch to SPDX license identifiers remoteproc/omap: Add watchdog functionality for remote processors remoteproc/omap: Report device exceptions and trigger recovery remoteproc/omap: Add support for runtime auto-suspend/resume remoteproc/omap: Add support for system suspend/resume remoteproc/omap: Request a timer(s) for remoteproc usage remoteproc/omap: Check for undefined mailbox messages remoteproc/omap: Remove the platform_data header remoteproc/omap: Add support for DRA7xx remote processors remoteproc/omap: Initialize and assign reserved memory node remoteproc/omap: Add the rproc ops .da_to_va() implementation remoteproc/omap: Add support to parse internal memories from DT remoteproc/omap: Add a sanity check for DSP boot address alignment remoteproc/omap: Add device tree support dt-bindings: remoteproc: Add OMAP remoteproc bindings remoteproc: qcom: Introduce panic handler for PAS and ADSP remoteproc: qcom: q6v5: Add common panic handler remoteproc: Introduce "panic" callback in ops remoteproc: Traverse rproc_list under RCU read lock remoteproc: Fix NULL pointer dereference in rproc_virtio_notify ...
