[Intel-gfx] [PATCH v5 4/7] drm/i915/hdcp: Refactor HDCP API structures

Suraj Kandpal suraj.kandpal at intel.com
Mon Jan 2 05:40:44 UTC 2023


It requires to move intel specific HDCP API structures to
i915_cp_fw_hdcp_interface.h from driver/misc/mei/hdcp/mei_hdcp.h
so that any content protection fw interfaces can use these
structures.
