Subject: [PATCH v5 0/6] TI K3 DSP remoteproc driver for C66x DSPs

Hi All,

The following is v5 of the K3 DSP remoteproc driver supporting the C66x DSPs
on the TI K3 J721E SoCs. The patches apply cleanly both on v5.8-rc1 as well
as on latest HEAD of rproc-next branch. The C71x v3 still applies cleanly on
top of this series.

The main changes are on the bindings. The previously added common 
ti,k3-sci-rproc.yaml remoteproc binding (v4 patch#3) is replaced by an
equivalent generic ti,k3-sci-common.yaml binding (patch #1) that can scale
to other TI SCI controller nodes. As such, I have relocated the file to 
Documentation/devicetree/bindings/arm/keystone folder instead of the
remoteproc folder. Driver patches are unchanged.

Please see the v4 cover-letter and individual patches for further delta
differences.

v4: https://patchwork.kernel.org/cover/11671459/
v3: https://patchwork.kernel.org/cover/11602331/
v2: https://patchwork.kernel.org/cover/11561787/
v1: https://patchwork.kernel.org/cover/11458573/

C71x v3: https://patchwork.kernel.org/cover/11602345/

regards
Suman
