Hi All,

The following is v2 of the K3 DSP remoteproc driver supporting the C66x DSPs
on the TI K3 J721E SoCs. The patches are based on the latest commit on the
rproc-next branch, 7dcef3988eed ("remoteproc: Fix an error code in
devm_rproc_alloc()").

I realized I also had the R5F patches on my branch, so the third patch won't apply cleanly (conflict on Makefile). Let me know if you want a new revision posted for you to pick up the series.

Suman


v2 includes a new remoteproc core patch (patch 1) that adds an OF helper
for parsing the firmware-name property. This is refactored out to avoid
replicating the code in various remoteproc drivers. Please see the
individual patches for detailed changes.

The main dependent patches from the previous series are now staged in
rproc-next branch. The only dependency for this series is the common
ti-sci-proc helper between R5 and DSP drivers [1]. Please see the initial
cover-letter [2] for v1 details.

regards
Suman
