Hi All,
This is a refresh of the unaccepted patches from an old series [1]. Patches 2 and 3 from that series were merged and these are rebased and revised versions of the same patches. I had forgotten about these patches, and am resurrecting these again. Patches are on top of latest 5.10-rc4.
The features being introduced here will be needed by the recently posted PRU remoteproc driver [2] in addition to the existing Wkup M3 remoteproc driver. Both of these drivers follow a client-driven boot methodology, with the latter strictly booted by another driver in kernel. The PRU remoteproc driver will be supporting both in-kernel clients as well as control from userspace orthogonally. The logic though is applicable and useful to any remoteproc driver not using 'auto-boot' and using an external driver/application to boot the remoteproc.
regards Suman
