ps3: Add passthru support for non-audio streams
Add support for the channel status bit setting so that non-PCM data stream can be sent (i.e. pass-through) via SPDIF/HDMI. Signed-off-by: Masakazu Mokuno <mokuno@sm.sony.co.jp> Acked-by: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
