drm/i915: Initialize HDCP2.2
Add the HDCP2.2 initialization to the existing HDCP1.4 stack.
v2:
mei interface handle is protected with mutex. [Chris Wilson]
v3:
Notifiers are used for the mei interface state.
v4:
Poll for mei client device state
Error msg for out of mem [Uma]
Inline req for init function removed [Uma]
v5:
Rebase as Part of reordering.
Component is used for the I915 and MEI_HDCP interface [Daniel]
v6:
HDCP2.2 uses the I915 component master to communicate with mei_hdcp
- [Daniel]
Required HDCP2.2 variables defined [Sean Paul]
v7:
intel_hdcp2.2_init returns void [Uma]
Realigning the codes.
v8:
Avoid using bool structure members.
MEI interface related changes are moved into separate patch.
Commit msg is updated accordingly.
intel_hdcp_exit is defined and used from i915_unload
v9:
Movement of the hdcp_check_link is moved to new patch [Daniel]
intel_hdcp2_exit is removed as mei_comp will be unbind in i915_unload.
v10:
bool is used in struct to make coding simpler. [Daniel]
hdmi hdcp init is placed correctly after encoder attachment.
v11:
hdcp2_capability check is moved into hdcp.c [Tomas]
