Most of the changes to the 62.0.0 firmware revolved around CTB communication channel. Conform to the new (stable) CTB protocol. v2: (Michal) Add values back to kernel DOC for actions (Docs) Add 'CT buffer' back in to fix warning Signed-off-by: John Harrison <John.C.Harrison@Intel.com> Signed-off-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> [mattrope: Tweaked kerneldoc while pushing as suggested by Daniele/Michal] Signed-off-by: Matt Roper <matthew.d.roper@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210616001302.84233-3-matthew.brost@intel.com
