-# HAL for MOST Sound Card
-
-## Introduction
-This Hardware Abstraction Layer (HAL) is intended to control MOST audio via
-standard ALSA mixer controls. Therefore the HAL add's controls to the MOST sound
-card. Modification of the mixer controls is mapped to control commands which are
-send to MOST nodes.
-
-The HAL requires to access the UNICENS V2 binding which is setting up the MOST
-network and the MOST node.
-
-Please check the following required components:
-* MOST Linux Driver
-* User must be member of "audio" group
-* UNICENS V2 binding
-* [K2L MOST150 Audio 5.1 Kit](https://www.k2l.de/products/74/MOST150%20Audio%205.1%20Kit/)
-
-## Possible Modifications
-Check if you need to adapt the default path for UNICENS configuration, e.g.
-```
-#define XML_CONFIG_PATH "/opt/AGL/unicens2-binding/config_multichannel_audio_kit.xml"
-```
-
-Check if you need to adapt the name of the MOST sound card.
-```
-#define ALSA_CARD_NAME  "Microchip MOST:1"
-```
-
-You can check your MOST sound card name by calling ```aplay -l```, e.g.
-```
-aplay -l
-**** List of PLAYBACK Hardware Devices ****
-card 0: PCH [HDA Intel PCH], device 0: 92HD90BXX Analog [92HD90BXX Analog]
-  Subdevices: 1/1
-  Subdevice #0: subdevice #0
-card 1: ep016ch [Microchip MOST:1], device 0: ep01-6ch []
-  Subdevices: 1/1
-  Subdevice #0: subdevice #0
-card 2: ep022ch [Microchip MOST:2], device 0: ep02-2ch []
-  Subdevices: 1/1
-  Subdevice #0: subdevice #0
-
-```
-Choose the first sound card with 6 channels, e.g. if you see ```ep01-6ch``` just
-take ```Microchip MOST:1```.
-
-If you get messed up with card enumeration the following action may help:
-- Unplug your MOST USB hardware from target
-- Call ```sudo rm /var/lib/alsa/asound.state```
-- Connect MOST USB hardware after reboot or restart of ALSA

-WRAP-JSON facility

-==================

-

-The facility wrap-json is based on the pack/unpack API on the

-libray jansson. The two chapters below are copied from the

-documentation of jansson library copyrighted by Petri Lehtinen

-(see at end).

-

-Building Values

----------------

-

-This section describes functions that help to create, or *pack*, complex

-JSON values, especially nested objects and arrays. Value building is

-based on a *format string* that is used to tell the functions about the

-expected arguments.

-

-For example, the format string `"i"` specifies a single integer value,

-while the format string `"[ssb]"` or the equivalent `"[s, s, b]"`

-specifies an array value with two strings and a boolean as its items:

-

-    /* Create the JSON integer 42 */

-    wrap_json_pack(&result, "i", 42);

-

-    /* Create the JSON array ["foo", "bar", true] */

-    wrap_json_pack(&result, "[ssb]", "foo", "bar", 1);

-

-Here's the full list of format specifiers. The type in parentheses

-denotes the resulting JSON type, and the type in brackets (if any)

-denotes the C type that is expected as the corresponding argument or

-arguments.

-

-`s` (string) \[const char \*\]

-

-:   Convert a null terminated UTF-8 string to a JSON string.

-

-`s?` (string) \[const char \*\]

-

-:   Like `s`, but if the argument is *NULL*, output a JSON null value.

-

-`s*` (string) \[const char \*\]

-

-:   Like `s`, but if the argument is *NULL*, do not output any value.

-    This format can only be used inside an object or an array. If used

-    inside an object, the corresponding key is additionally suppressed

-    when the value is omitted. See below for an example.

-

-`s#` (string) \[const char \*, int\]

-

-:   Convert a UTF-8 buffer of a given length to a JSON string.

-

-`s%` (string) \[const char \*, size\_t\]

-

-:   Like `s#` but the length argument is of type size\_t.

-

-`+` \[const char \*\]

-

-:   Like `s`, but concatenate to the previous string. Only valid after

-    `s`, `s#`, `+` or `+#`.

-

-`+#` \[const char \*, int\]

-

-:   Like `s#`, but concatenate to the previous string. Only valid after

-    `s`, `s#`, `+` or `+#`.

-

-`+%` (string) \[const char \*, size\_t\]

-

-:   Like `+#` but the length argument is of type size\_t.

-

-`n` (null)

-

-:   Output a JSON null value. No argument is consumed.

-

-`b` (boolean) \[int\]

-

-:   Convert a C int to JSON boolean value. Zero is converted to `false`

-    and non-zero to `true`.

-

-`i` (integer) \[int\]

-

-:   Convert a C int to JSON integer.

-

-`I` (integer) \[json\_int\_t\]

-

-:   Convert a C json\_int\_t to JSON integer.

-

-`f` (real) \[double\]

-

-:   Convert a C double to JSON real.

-

-`o` (any value) \[json\_t \*\]

-

-:   Output any given JSON value as-is. If the value is added to an array

-    or object, the reference to the value passed to `o` is stolen by the

-    container.

-

-`O` (any value) \[json\_t \*\]

-

-:   Like `o`, but the argument's reference count is incremented. This is

-    useful if you pack into an array or object and want to keep the

-    reference for the JSON value consumed by `O` to yourself.

-

-`o?`, `O?` (any value) \[json\_t \*\]

-

-:   Like `o` and `O`, respectively, but if the argument is *NULL*,

-    output a JSON null value.

-

-`o*`, `O*` (any value) \[json\_t \*\]

-

-:   Like `o` and `O`, respectively, but if the argument is *NULL*, do

-    not output any value. This format can only be used inside an object

-    or an array. If used inside an object, the corresponding key is

-    additionally suppressed. See below for an example.

-

-`[fmt]` (array)

-

-:   Build an array with contents from the inner format string. `fmt` may

-    contain objects and arrays, i.e. recursive value building is

-    supported.

-

-`{fmt}` (object)

-

-:   Build an object with contents from the inner format string `fmt`.

-    The first, third, etc. format specifier represent a key, and must be

-    a string (see `s`, `s#`, `+` and `+#` above), as object keys are

-    always strings. The second, fourth, etc. format specifier represent

-    a value. Any value may be an object or array, i.e. recursive value

-    building is supported.

-

-Whitespace, `:` and `,` are ignored.

-

-More examples:

-

-    /* Build an empty JSON object */

-    wrap_json_pack(&result, "{}");

-

-    /* Build the JSON object {"foo": 42, "bar": 7} */

-    wrap_json_pack(&result, "{sisi}", "foo", 42, "bar", 7);

-

-    /* Like above, ':', ',' and whitespace are ignored */

-    wrap_json_pack(&result, "{s:i, s:i}", "foo", 42, "bar", 7);

-

-    /* Build the JSON array [[1, 2], {"cool": true}] */

-    wrap_json_pack(&result, "[[i,i],{s:b}]", 1, 2, "cool", 1);

-

-    /* Build a string from a non-null terminated buffer */

-    char buffer[4] = {'t', 'e', 's', 't'};

-    wrap_json_pack(&result, "s#", buffer, 4);

-

-    /* Concatenate strings together to build the JSON string "foobarbaz" */

-    wrap_json_pack(&result, "s++", "foo", "bar", "baz");

-

-    /* Create an empty object or array when optional members are missing */

-    wrap_json_pack(&result, "{s:s*,s:o*,s:O*}", "foo", NULL, "bar", NULL, "baz", NULL);

-    wrap_json_pack(&result, "[s*,o*,O*]", NULL, NULL, NULL);

-

-Parsing and Validating Values

------------------------------

-

-This section describes functions that help to validate complex values

-and extract, or *unpack*, data from them. Like building values

-&lt;apiref-pack&gt;, this is also based on format strings.

-

-While a JSON value is unpacked, the type specified in the format string

-is checked to match that of the JSON value. This is the validation part

-of the process. In addition to this, the unpacking functions can also

-check that all items of arrays and objects are unpacked. This check be

-enabled with the format specifier `!` or by using the flag

-`JSON_STRICT`. See below for details.

-

-Here's the full list of format specifiers. The type in parentheses

-denotes the JSON type, and the type in brackets (if any) denotes the C

-type whose address should be passed.

-

-`s` (string) \[const char \*\]

-

-:   Convert a JSON string to a pointer to a null terminated UTF-8

-    string. The resulting string is extracted by using

-    json\_string\_value() internally, so it exists as long as there are

-    still references to the corresponding JSON string.

-

-`s%` (string) \[const char \*, size\_t \*\]

-

-:   Convert a JSON string to a pointer to a null terminated UTF-8 string

-    and its length.

-

-`n` (null)

-

-:   Expect a JSON null value. Nothing is extracted.

-

-`b` (boolean) \[int\]

-

-:   Convert a JSON boolean value to a C int, so that `true` is converted

-    to 1 and `false` to 0.

-

-`i` (integer) \[int\]

-

-:   Convert a JSON integer to C int.

-

-`I` (integer) \[json\_int\_t\]

-

-:   Convert a JSON integer to C json\_int\_t.

-

-`f` (real) \[double\]

-

-:   Convert a JSON real to C double.

-

-`F` (integer or real) \[double\]

-

-:   Convert a JSON number (integer or real) to C double.

-

-`o` (any value) \[json\_t \*\]

-

-:   Store a JSON value with no conversion to a json\_t pointer.

-

-`O` (any value) \[json\_t \*\]

-

-:   Like `O`, but the JSON value's reference count is incremented.

-

-`[fmt]` (array)

-

-:   Convert each item in the JSON array according to the inner format

-    string. `fmt` may contain objects and arrays, i.e. recursive value

-    extraction is supported.

-

-`{fmt}` (object)

-

-:   Convert each item in the JSON object according to the inner format

-    string `fmt`. The first, third, etc. format specifier represent a

-    key, and must be `s`. The corresponding argument to unpack functions

-    is read as the object key. The second fourth, etc. format specifier

-    represent a value and is written to the address given as the

-    corresponding argument. **Note** that every other argument is read

-    from and every other is written to.

-

-    `fmt` may contain objects and arrays as values, i.e. recursive value

-    extraction is supported.

-

-`!`

-

-:   This special format specifier is used to enable the check that all

-    object and array items are accessed, on a per-value basis. It must

-    appear inside an array or object as the last format specifier before

-    the closing bracket or brace.

-

-`*`

-

-:   This special format specifier is the opposite of `!`. This is the default.

-    It must appear inside an array or object as the last format specifier

-    before the closing bracket or brace.

-

-Whitespace, `:` and `,` are ignored.

-

-Examples:

-

-    /* root is the JSON integer 42 */

-    int myint;

-    wrap_json_unpack(root, "i", &myint);

-    assert(myint == 42);

-

-    /* root is the JSON object {"foo": "bar", "quux": true} */

-    const char *str;

-    int boolean;

-    wrap_json_unpack(root, "{s:s, s:b}", "foo", &str, "quux", &boolean);

-    assert(strcmp(str, "bar") == 0 && boolean == 1);

-

-    /* root is the JSON array [[1, 2], {"baz": null} */

-    wrap_json_check(root, "[[i,i], {s:n}]", "baz");

-    /* returns 0 for validation success, nothing is extracted */

-

-    /* root is the JSON array [1, 2, 3, 4, 5] */

-    int myint1, myint2;

-    wrap_json_unpack(root, "[ii!]", &myint1, &myint2);

-    /* returns -1 for failed validation */

-

-    /* root is an empty JSON object */

-    int myint = 0, myint2 = 0, myint3 = 0;

-    wrap_json_unpack(root, "{s?i, s?[ii]}",

-                "foo", &myint1,

-                "bar", &myint2, &myint3);

-    /* myint1, myint2 or myint3 is no touched as "foo" and "bar" don't exist */
