Hello All, This series adds deferred probe functionality in the TI's Remoteproc drivers. The remoteproc drivers are dependent on the omap-mailbox driver for mbox functionalities. Sometimes, the remoteproc driver could be probed before the mailbox driver leading to rproc boot failures. Thus, defer the probe routine of remoteproc drivers until mailbox driver is probed by checking the mbox_request_channel handle in probe. Also, use the acquired mbox handle in probe during rproc start/attach routine instead of re-requesting. Do not free mbox handle during stop/detach routine or error paths. This makes our k3_rproc_attach() & k3_rproc_detach() functions NOP. Also, use the devm_rproc_alloc() helper to automatically free created rprocs incase of a probe defer.
