Make it possible that userspace can query all performance domains and its signals. This information is needed to sample those signals via submit ioctl. At the moment no performance domain is available. Changes from v1 -> v2: - use a 16 bit value for signals - fix padding issues - add id member to domain and signal struct Changes v4 -> v5 - provide for each pipe an own set of pm domains Signed-off-by: Christian Gmeiner <christian.gmeiner@gmail.com> Signed-off-by: Lucas Stach <l.stach@pengutronix.de>
