This series adds support for ARM Coresight SoC-600 IP, which implements Coresight V3 architecture. It also does some clean up of the replicator driver namings used in the driver to prevent confusions to the user.
The SoC-600 comes with an improved TMC which supports new features, including Save-Restore and Software FIFO2 mode (for streaming the trace data over functional I/O like USB/PCI). This series only supports Save-Restore feature of the new ETR by reusing the driver to perform additional setups required in case we are dealing with an IP which supports it. Towards this, we add a capability description to the IP listings to make it easier.
Patches 1-8 contains general cleanups, introduction of some helper routines. Patch 9 introduces the capability tracking for TMCs. Patch 10 adds the support for Save-Restore feature in ETR. Patch 11 adds support for the Coresight SoC 600 TMC Patch 12 adds the support for other components in SoC 600.
Tested on Juno (with Coresight SoC 400) and an FPGA based system for SoC 600. Applies on Mathieu's coresight/next.
Changes since V1 - Rename coresight-replicator-qcom.c => coresight-dynamic-replicator.c - Fix PIDR2 codings for ETB-10, ETM3x - Fix cosmetic issues pointed out by Mathieu - Fix commit description for "coresight tmc: Handle configuration types properly" - Drop SWFIFO2 from the capability of SoC-600 TMC
