-Devicetree bindings for the Axentia TSE-850 audio complex

-Required properties:
-  - compatible: "axentia,tse850-pcm5142"
-  - axentia,cpu-dai: The phandle of the cpu dai.
-  - axentia,audio-codec: The phandle of the PCM5142 codec.

-  - axentia,loop1-gpios: gpio specifier that controls loop relays on channel 1.
-  - axentia,loop2-gpios: gpio specifier that controls loop relays on channel 2.
-  - axentia,ana-supply: Regulator that supplies the output amplifier. Must
-    support voltages in the 2V - 20V range, in 1V steps.

-The 'loop1' gpio pin controls two relays, which are either in loop position,
-meaning that input and output are directly connected, or they are in mixer
-position, meaning that the signal is passed through the 'Sum' mixer. Similarly
-for 'loop2'.
-
-In the above, the 'loop1' relays are inactive, thus feeding IN1 to the mixer
-(if 'add' is active) and feeding the mixer output to OUT1. The 'loop2' relays
-are active, short-cutting the TSE-850 from channel 2. IN1, IN2, OUT1 and OUT2
-are TSE-850 connectors and DAC is the PCB name of the (filtered) output from
-the PCM5142 codec.

+description: |
+  The TSE-850 is an FM Transmitter Station Equipment, designed to generate
+  baseband signals for FM, mainly the DARC subcarrier, but other signals
+  are also possible.
+
+  The schematics explaining the gpios are as follows::
+
+                 loop1 relays
+     IN1 +---o  +------------+  o---+ OUT1
+              \                /
+               +              +
+               |   /          |
+               +--o  +--.     |
+               |  add   |     |
+               |        V     |
+               |      .---.   |
+     DAC +----------->|Sum|---+
+               |      '---'   |
+               |              |
+               +              +
+     IN2 +---o--+------------+--o---+ OUT2
+                 loop2 relays
+
+  The 'loop1' gpio pin controls two relays, which are either in loop
+  position, meaning that input and output are directly connected, or
+  they are in mixer position, meaning that the signal is passed through
+  the 'Sum' mixer. Similarly for 'loop2'.
+
+  In the above, the 'loop1' relays are inactive, thus feeding IN1 to the
+  mixer (if 'add' is active) and feeding the mixer output to OUT1. The
+  'loop2' relays are active, short-cutting the TSE-850 from channel 2.
+  IN1, IN2, OUT1 and OUT2 are TSE-850 connectors and DAC is the PCB name
+  of the (filtered) output from the PCM5142 codec.
