		* Return the currently negotiated and max supported HDCP levels.
		*
		* This method only differs from @1.1 version by the addition of
		* support for HDCP 2.3.
		*
		* The current level is based on the display(s) the device is connected to.
		* If multiple HDCP-capable displays are simultaneously connected to
		* separate interfaces, this method returns the lowest negotiated HDCP level
		* of all interfaces.
		*
		* The maximum HDCP level is the highest level that can potentially be
		* negotiated. It is a constant for any device, i.e. it does not depend on
		* downstream receiving devices that could be connected. For example, if
		* the device has HDCP 1.x keys and is capable of negotiating HDCP 1.x, but
		* does not have HDCP 2.x keys, then the maximum HDCP capability would be
		* reported as 1.x. If multiple HDCP-capable interfaces are present, it
		* indicates the highest of the maximum HDCP levels of all interfaces.
		*
		* This method should only be used for informational purposes, not for
		* enforcing compliance with HDCP requirements. Trusted enforcement of HDCP
		* policies must be handled by the DRM system.
		*
		* @return status the status of the call. The status must be OK or
		* ERROR_DRM_INVALID_STATE if the HAL is in a state where the HDCP
		* level cannot be queried.
		* @return connectedLevel the lowest HDCP level for any connected
		* displays
		* @return maxLevel the highest HDCP level that can be supported
		* by the device
