Subject: [PATCH 0/8] New remoteproc driver for TI PRU
This series adds a new remoteproc driver for the TI Programmable
Runtime Unit
(PRU) that is present in some TI Sitara processors. This code has
been tested
working on AM1808 (LEGO MINDSTORMS EV3) and AM3358 (BeagleBone Green).
This is great. We have been working on something similar and I think
it would
be great if we can collaborate to get all our needs addressed.
Yes, I have used the PRU with the TI kernel on BeagleBone so I've seen
the TI
implementation. My primary interest is in the AM1808, which has a far
simpler
PRU than other SoCs. So, I was hoping I could get away with just
implementing
the basic stuff that I need and let TI add the more complex stuff later.
Thanks for the series. PRUSS is present on many SoCs now, and each with
their own integration quirks, both in terms of SoC connections as well
as internal sub-modules within the subsystem. We currently support
AM335x, AM437x, AM57xx, Keystone 2 based 66AK2G and a newer generation
AM65x as well. It should be relatively straight-forward to scale this
for AM1808/OMAP-L138 as well. The move to the standard Common Clock and
Reset frameworks for clocks with the Davinci chips should make it
relatively straight-forward for the architecture pieces.
I will take a look at your series in detail sometime next week, and
mostly post our series to the upstream lists as well within the next
couple of weeks so that it is easier for discussion on the upstream lists.
Have you had time to look at this yet? If you are too busy, I can submit
a v2 with the interrupt controller broken out into a separate driver.
