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 keep track of the capabilities of the given TMC ETR. Some of the features are advertised via DEVID register (address width, scatter gather support), while some are not (save-restore). So we attach a static capability mask with the device PID for the unadvertised features and detect the rest at device probe.
Tested on Juno (with Coresight SoC 400) and an FPGA based system for SoC 600.
Applies on v4.13-rc1
Changes since V3: - Rebased to v4.13-rc1 - Rename AxCACHE => AXCACHE, suggested by Mathieu - Fix checkpatch warnings againt space in comments. - Remove device initialisation message for replicator. - Add Reviewed-by tags for the DTS changes.
Changes since V2: - Fix typos in masks for ETM3. - Fix all dts for obsoleted compatible string for replicator. - Detect advertised capabilities at runtime. - Add support for detecting the address width at runtime, new feature in SoC-600. - Add support for split ARCACHE/WCACHE encoding for AXI transactions
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
