[alsa-devel] PATCH - ESI Juli driver

Hi Takashi,

Juli support required some changes to ice1724.c/ice1712.h. Since Juli 
uses different clock scheme than most other ice1712/24 cards, I had to 
move all clock-specific code to card-specific routines. Most of them are 
redefined in juli.c.

The driver is tested, only analog-in and digital-in monitors are not 
working. I have coded according to manufacturer's documentation, the 
same procedure is in OSS Juli driver. I described the issue in detail in 
the code, perhaps someone will do more research.

The card itself has no HW master volume control. It would have to be 
implemented as a virtual control manipulating internal values of PCM and 
monitor volume controls. I will take a look at it later. For now, 
perhaps we could rename the PCM Volume to Master Volume, as most people 
will not need the monitoring anyway. I will leave it to your decision.

* moving all clock-specific code to card-specific routines
* support for ESI Juli
* to-be-researched - monitoring of analog/digital inputs
* missing - master volume control, will have to be implemented as 
virtual, no HW support.
