2017-03-28ALSA: firewire-motu: enable to read transaction cache via hwdep interfaceTakashi Sakamoto
MOTU FireWire series can transfer messages to registered address. These messages are transferred for the status of internal clock synchronization just after starting streams. When the synchronization is stable, it's 0x01ffffff. Else, it's 0x05ffffff. This commit adds a functionality for user space applications to receive content of the message.

2017-03-28ALSA: firewire-motu: add hwdep interfaceTakashi Sakamoto
This commit adds hwdep interface so as the other sound drivers for units on IEEE 1394 bus have. This interface is designed for mixer/control applications. By using this interface, an application can get information about firewire node, can lock/unlock kernel streaming and can get notification at starting/stopping kernel streaming.
