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 Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai --- diff --git a/sound/firewire/Kconfig b/sound/firewire/Kconfig index b3e274f..8cd4f1f 100644 --- a/sound/firewire/Kconfig +++ b/sound/firewire/Kconfig @@ -61,4 +61,18 @@ config SND_SCS1X To compile this driver as a module, choose M here: the module will be called snd-scs1x. +config SND_FIREWORKS + tristate "Echo Fireworks board module support" + help + Say Y here to include support for FireWire devices based + on Echo Digital Audio Fireworks board: + * 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 + + To compile this driver as a module, choose M here: the module + will be called snd-fireworks. + endif # SND_FIREWIRE diff --git a/sound/firewire/Makefile b/sound/firewire/Makefile index 5099550..5cd39dc 100644 --- a/sound/firewire/Makefile +++ b/sound/firewire/Makefile @@ -10,3 +10,4 @@ obj-$(CONFIG_SND_DICE) += snd-dice.o obj-$(CONFIG_SND_FIREWIRE_SPEAKERS) += snd-firewire-speakers.o obj-$(CONFIG_SND_ISIGHT) += snd-isight.o obj-$(CONFIG_SND_SCS1X) += snd-scs1x.o +obj-$(CONFIG_SND_FIREWORKS) += fireworks/ diff --git a/sound/firewire/fireworks/Makefile b/sound/firewire/fireworks/Makefile new file mode 100644 index 0000000..99f6fc3 --- /dev/null +++ b/sound/firewire/fireworks/Makefile @@ -0,0 +1,2 @@ +snd-fireworks-objs := fireworks.o +obj-m += snd-fireworks.o diff --git a/sound/firewire/fireworks/fireworks.c b/sound/firewire/fireworks/fireworks.c new file mode 100644 index 0000000..ad719a1 --- /dev/null +++ b/sound/firewire/fireworks/fireworks.c @@ -0,0 +1,182 @@ +/* + * fireworks.c - a part of driver for Fireworks based devices + * + * Copyright (c) 2009-2010 Clemens Ladisch + * Copyright (c) 2013-2014 Takashi Sakamoto + * + * Licensed under the terms of the GNU General Public License, version 2. + */ + +/* + * Fireworks is a board module which Echo Audio produced.
