I gave it a quick check and bumped the version number in the docs for the next release, but the month is an estimate. Thanks Changes since v2: * Rebased onto coresight/next (b99ee26a1a) * Bumped release version to 6.1 Changes since v1: * Inline etmv4_to_ts_source() function. * Collect review tag from Leo.
