Currently we are only checking capability of remote device and not immediate downstream device but during capability check we need are concerned with only the HDCP capability of downstream device. During i915_display_info reporting we need HDCP Capability for both the monitors and downstream branch device if any this patch adds that. --v2 -Use MST Hub HDCP version [Ankit] --v3 -Redefined how we seprate remote and direct read to make sure HDMI shim functions are not touched [Ankit] --v4 - Fix the conditions so that hdcp_info with remote_req true is sent only when encoder is mst [Ankit] Signed-off-by: Suraj Kandpal <suraj.kandpal@intel.com> --- .../drm/i915/display/intel_display_debugfs.c | 25 +++++++++++++++---- 1 file changed, 20 insertions(+), 5 deletions(-)
