Re: [alsa-devel] [PATCH 19/39] fireworks: Add skelton for Fireworks based devices

This commit adds a new driver with no functionality. This driver just creates/removes card instance according to callbacks.

Fireworks is a board module which Echo Audio produced. This module consists of three chipsets:

• Communication chipset for IEEE1394 PHY/Link and IEC 61883-1/6
• DSP or/and FPGA for signal processing
• Flash Memory to store firmwares

Current supported devices:

• Mackie Onyx 400F/1200F
• Echo AudioFire12/8(until 2009 July)
• Echo AudioFire2/4/Pre8/8(since 2009 July)
• Echo Fireworks 8/HDMI
• Gibson Robot Interface pack/GoldTop

Now we may handle more than 32 cards, depending on Kconfig. Use bitmap instead.
