This commit is a supplement to my previous patch. http://mailman.alsa-project.org/pipermail/alsa-devel/2014-July/079190.html The special_clk_ctl_put() still returns 0 in error handling case. It should return -EINVAL. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>

/*
|
|
* Just powering on, Firewire 410/Audiophile/1814 and ProjectMix I/O wait to
|
|
* download firmware blob. To enable these devices, drivers should upload
|
|
* firmware blob and send a command to initialize configuration to factory
|
|
* settings when completing uploading. Then these devices generate bus reset
|
|
* and are recognized as new devices with the firmware.
|
|
*
|
|
* But with firmware version 5058 or later, the firmware is stored to flash
|
|
* memory in the device and drivers can tell bootloader to load the firmware
|
|
* by sending a cue. This cue must be sent one time.
|
|
*
|
|
* For streaming, both of output and input streams are needed for Firewire 410
|
|
* and Ozonic. The single stream is OK for the other devices even if the clock
|
|
* source is not SYT-Match (I note no devices use SYT-Match).
|
|
*
|
|
* Without streaming, the devices except for Firewire Audiophile can mix any
|
|
* input and output. For this reason, Audiophile cannot be used as standalone
|
|
* mixer.
|
|
*
|
|
* Firewire 1814 and ProjectMix I/O uses special firmware. It will be freezed
|
|
* when receiving any commands which the firmware can't understand. These
|
|
* devices utilize completely different system to control. It is some
|
|
* write-transaction directly into a certain address. All of addresses for mixer
|
|
* functionality is between 0xffc700700000 to 0xffc70070009c.
