Subject: [PATCH v3 0/6] TI K3 DSP remoteproc driver for C66x DSPs

Hi All,

The following is v3 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
master branch 44ebe016df3a.

The main changes in v3 are mostly around the bindings to address various
comments from Rob. The bindings patch is the only patch without an Ack on
v2.

Main changes in v3:
 - Introduced a new common ti-sci-proc bindings yaml file (Patch #3)
   that can be used by both K3 DSP and R5F
 - Updated dt-bindings to address most comments (Patch #4)
 - Moved the common ti-sci-helper patch (Patch #2) between R5 and DSP drivers
   from the R5F series to this series, so that this series is standalone and
   can be merged by itself.

Please see the individual patches for further delta differences.

v2: https://patchwork.kernel.org/cover/11561787/
v1: https://patchwork.kernel.org/cover/11458573/

regards
Suman
