Update the get/set min/max freq hooks to work for SLPC case as well. Consolidate helpers for requested/min/max frequency get/set to intel_rps where the proper action can be taken depending on whether SLPC is enabled. v2: Add wrappers for getting rp0/1/n frequencies, update softlimits in set min/max SLPC functions. Also check for boundary conditions before setting them. v3: Address review comments (Michal W) v4: Add helper for host part of intel_rps_set_freq helpers (Michal W) v5: checkpatch() Reviewed-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Acked-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Signed-off-by: Vinay Belgaumkar <vinay.belgaumkar@intel.com> Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> Signed-off-by: Sujaritha Sundaresan <sujaritha.sundaresan@intel.com> Signed-off-by: John Harrison <John.C.Harrison@Intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210730202119.23810-13-vinay.belgaumkar@intel.com
