[PATCH 0/2] Add Coresight support for RB5 board

[PATCH 0/2] Add Coresight support for RB5 board

[Tao Zhang]

This series adds Coresight support for SM8250 Soc on RB5 board.
It is composed of two elements.
a) Add ETM PID for Kryo-5XX.
b) Add coresight support to DTS for RB5.

This series applies to coresight/next
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git

[PATCH 1/2] coresight: etm4x: Add ETM PID for Kryo-5XX

[Tao Zhang]

Add ETM PID for Kryo-5XX to the list of supported ETMs.
Otherwise, Kryo-5XX ETMs will not be initialized successfully.
e.g.
This change can be verified on qrb5165-rb5 board. ETM4-ETM7 nodes
will not be visible without this change.

I have added your work to my patchset queue.  On the other hand I have
a lot of patches to review these days and as such won't be able to
look at it for 4 to 5 weeks.

Please could you add Cortex-A77 to the comment ? Otherwise looks good to me.

Are there any sinks at all ? (TMC-ETR ?).
