drm/i915: Implement HDCP for DisplayPort
This patch adds HDCP support for DisplayPort connectors by implementing the intel_hdcp_shim. Most of this is straightforward read/write from/to DPCD registers. One thing worth pointing out is the Aksv output bit. It wasn't easily separable like it's HDMI counterpart, so it's crammed in with the rest of it. Changes in v2: - Moved intel_hdcp_check_link out of intel_dp_check_link and only call it on short pulse. Since intel_hdcp_check_link does its own locking, this ensures we don't deadlock when intel_dp_check_link is called holding connection_mutex. - Rebased on drm-intel-next Changes in v3: - Initialize new worker Changes in v4: - Use intel_hdcp_init (Daniel) - Check for reauth requests in check_link (Ram) Changes in v5: - None Changes in v6: - Fix build warnings when printing ssize_t Cc: Daniel Vetter <[email protected]> Reviewed-by: Ramalingam C <[email protected]> Signed-off-by: Sean Paul <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
