ALSA: firewire-digi00x: add skeleton for Digi 002/003 family
This commit adds a new driver for Digidesign 002/003 family. This commit just creates/removes card instance according to bus event. More functions will be added in following commits. Digidesign 002/003 family consists of: * Agere FW802B for IEEE 1394 PHY layer * PDI 1394L40 for IEEE 1394 LINK layer and IEC 61883 interface * ALTERA ACEX EP1K50 for IEC 61883 layer and DSP controller * ADSP-21065L for signal processing [minor cleanup using skip_spaces() by tiwai] Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
