drm/i915/hdcp: Use generic names for HDCP helpers and structs
pre MTL we interact with mei interface to talk to firmware and enable CP but going forward we will talk to gsc cs because of which we are making all names for HDCP helpers and structures generic as either mei or gsc cs maybe used. Change the include/drm/i915_mei_hdcp_interface.h to include/drm/i915_hdcp_interface.h Change the i915_hdcp_interface.h header naming convention to suit generic f/w type. %s/MEI_/HDCP_ %s/mei_dev/hdcp_dev Change structure name Accordingly. %s/i915_hdcp_comp_master/i915_hdcp_master %s/i915_hdcp_component_ops/i915_hdcp_ops --v6 -make each patch build individually [Jani] --v8 -change ME FW to ME/GSC FW [Ankit] -fix formatting issue [Ankit] --v9 -fix commit message and header [Uma] --v10 -rename comp variable [Uma] Cc: Tomas Winkler <tomas.winkler@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Uma Shankar <uma.shankar@intel.com> Cc: Ankit Nautiyal <ankit.k.nautiyal@intel.com> Signed-off-by: Anshuman Gupta <anshuman.gupta@intel.com> Signed-off-by: Suraj Kandpal <suraj.kandpal@intel.com> Reviewed-by: Ankit Nautiyal <ankit.k.nautiyal@intel.com> Reviewed-by: Uma Shankar <uma.shankar@intel.com> Acked-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Uma Shankar <uma.shankar@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230316092927.668980-3-suraj.kandpal@intel.com
