This command create a new control using ID, description and value.
Syntax:
cset-new "name='ABCD',index=2 type=boolean,count=2 on,on"
cset-new "name='Enum' type=enum,labels='L1;L2;L3' 'L2'"

Actually, the BootSequence is executed only when the driver controls
(identifiers or value types) are changed. It may be handy to have
also a sequence which is executed at _each_ boot without any condition.

With the conditional blocks, it may be useful to terminate
the hardware detection from the configuration. Introduce
'Error' keyword for the master UCM configuration file.

The syntax is ${CardIdByName:CARDNAME[#INDEX]}.
The CARDNAME is the ALSA's soundcard name (short form).
The INDEX is the instance (0 = first, 1 = second etc.).
Example: ${CardIdByName:HDA Intel PCH}
(which is identical to ${CardIdByName:HDA Intel PCH#0})

There is a big issue to validate all possible configuration paths.
Let create ucm2/ucm.conf file which describe the lookups. It may
be also customized later to follow the kernel-side development.

Syntax:
DefineRegex.VariableName {
String "something to match"
Regex "(me)thi(ng)"
}
Result:
- configuration variable "VariableName" is equal to "mething"
- configuration variable "VariableName1" is equal to "me"
- configuration variable "VariableName2" is equal to "ng"
Notes:
The "Flags" string in the DefineRegex compound may specify
the compilation flags (e = extended, i = ignore case,
s = no substitutes, n = newline). See 'man 3 regex' for
more details.

It may be useful for the library files to use the runtime configuration
variables.
Example:
Define.Var1 "hw:${CardId},2"
Value.PlaybackPCM "${var:Var1}"

It is not necessary to maintain this information in sync in the configuration
files. Fill the missing entries to the complementary devices.

With the conditionals, it may be useful to define the devices
in the included configuration files. To satisfy the specification
requirements (device naming) those device names might require
to be renamed or deleted wrong references from the conflicting
or supported lists.

The new ucm2 expects that the longname directory is shared with
the driver directory. Fix that for 'Syntax 2'.

Otherwise, the conf_format is not set in this scenario.
