This introduces device managed versions of functions used to register remoteproc devices, add support for remoteproc driver specific resource control, enables remoteproc drivers to specify ELF class and machine for coredumps. It integrates pm_runtime in the core for keeping resources active while the remote is booted and holds a wake source while recoverying a remote processor after a firmware crash. It refactors the remoteproc device's allocation path to simplify the logic, fix a few cleanup bugs and to not clone const strings onto the heap. Debugfs code is simplifies using the DEFINE_SHOW_ATTRIBUTE and a zero-length array is replaced with flexible-array. A new remoteproc driver for the JZ47xx VPU is introduced, the Qualcomm SM8250 gains support for audio, compute and sensor remoteprocs and the Qualcomm SC7180 modem support is cleaned up and improved. The Qualcomm glink subsystem-restart driver is merged into the main glink driver, the Qualcomm sysmon driver is extended to properly notify remote processors about all other remote processors' state transitions. -----BEGIN PGP SIGNATURE----- iQJPBAABCAA5FiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAl7egk0bHGJqb3JuLmFu ZGVyc3NvbkBsaW5hcm8ub3JnAAoJEAsfOT8Nma3FQnwQAM781m7BqSKdtbH0OzGB K4jGX/IkWCEluXx/RuDbPFV0mx/yLOfsrSzBBYnnTl+CXTgSLFtImRvwx5BFbnAl bRNbSlw1GLiV/w+HceIx1iKTELnkHKp4TT3zUmR+dZ+7pT1dhWXzHIjyjJPC1c7R L8qg3qlOrM620y3OJNUo57/20Tg9WN6kBKdaeyJKjmBsENrw6wggY30ijqhMgCYr 9LgStPjtuSGgf4j55+BeTskVSnOvuun5NlVpRUVTo+ZDKTZAyO/8TKM+yWffAHc5 7WkK0z9E3lhwdNPLif+dSIvhLjiyKR2yJf5KP7n9mFhA1tRVqNXnJqMCnAnwVvzT IpL1INYbirRwPfayhCsUSwKDTKkckKP9I/vZ7WKWJD9SWcc4eGWIifNDNGkMQ6qV 7S0+6AyCANBltRPKTl6zwXSrrHuBUNkH3r9gddT5tPJu7Klh+fjKEywpsXkUd+IY Xo1nuT+mYrUgif0KTh656EK6YM5dFuVnZqOszzgiVUrdKeHKYBsUjWD7vS7DBeLe pLiDfo0qMb/J0sPptMt+0Rg/b/Nt1YiddW3ZlnVmWRCRjIQRJt9LQZcQoVhVv1Sa OQkhlvFTqIEFJfLtvp83zvL5WngxVM5Dq6mDiesAjZUhyode9ZtOGxr9zyhA4ApU njqp4n16OxcXaqjwp+k6eK8L =4k54 -----END PGP SIGNATURE----- Merge tag 'rproc-v5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/andersson/remoteproc Pull remoteproc updates from Bjorn Andersson: "This introduces device managed versions of functions used to register remoteproc devices, add support for remoteproc driver specific resource control, enables remoteproc drivers to specify ELF class and machine for coredumps.
