Subject: [PATCH v4 0/5] coresight: TRBE and Self-Hosted trace fixes

Here is the updated patches from the v3 of the series [0], parts of which
have been queued to coresight/next. This series now applies on the
coresight/next branch.

Changes since v3:
 - Split the spurious IRQ handling patch to :
   a) coresight: trbe: irq handler: Do not disable TRBE if no action is needed
   b) coresight: trbe: Fix handling of spurious interrupts

 - Added a helper to mark the ring buffer when there is WRAP event
   and added a comment to explain.
