Don't other silicon vendors need a kicker API as well? > How are they kicking remote processors in other places? GPIOs? > In remoteproc I have two of these: 1) da8xx_remoteproc ioremaps a register and writes a bit in it (looks similar to the downstream Qualcomm way) 2) omap_remoteproc acquires a mbox channel, in which it writes a virtqueue id to kick the remote. So one of the two cases could have used such mechanism. We could write up a Qualcomm specific "kicker" and probe the mailing list regarding the interest in making that generic (i.e. changing the names in the API and DT binding). The sucky part is that I believe we have most of our kickers in place already so rpm, smd, smp2p, smsm etc would all need to support both mechanisms.
