[PATCH v4 0/4] TI K3 R5F remoteproc support

From: Suman Anna
Date: Tue Sep 08 2020 - 13:47:32 EST

Hi All,

The following is v4 of the TI K3 R5F remoteproc driver series supporting all
the R5F processor clusters/subsystems on TI AM65x and J721E SoCs. Please
see the v1 cover-letter [1] for the features supported on these R5F processors.

This series is a rebased version on top of the latest v5.9-rc baseline and
includes very minor fixes w.r.t v3. The previous K3 DSP dependencies are now
available in mainline kernel. Please see the individual patches for the delta
differences (Only patches 1 and 2 updated).

This series is only waiting on bindings ack and the conclusion on the bindings
discussion from v2 [4] on which I haven't seen any forward progress on this
despite all the clarifications. I do not expect any changes even w.r.t System DT,
and we can't really have a common binding between TI and Xilinx R5Fs. How can we
take this series forward? It is blocking us to get the various usecases that
leverage the remoteprocs upstream.
