Subject: Applied "ASoC: tse850: document axentia,tse850-pcm5142 bindings" to the asoc tree
The patch
ASoC: tse850: document axentia,tse850-pcm5142 bindings
has been applied to the asoc tree at
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git
All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark

Subject: [PATCH] ASoC: tse850: document axentia,tse850-pcm5142 bindings
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.

+Devicetree bindings for the Axentia TSE-850 audio complex
+
+Required properties:
+ - compatible: "axentia,tse850-pcm5142"
+ - axentia,ssc-controller: The phandle of the atmel SSC controller used as
+ cpu dai.
+ - axentia,audio-codec: The phandle of the PCM5142 codec.
+ - axentia,add-gpios: gpio specifier that controls the mixer.
+ - 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 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 controlls 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.
+
+Example:
+
+ &i2c {
+ codec: pcm5142@4c {
+ compatible = "ti,pcm5142";
+
+ reg = <0x4c>;
+
+ AVDD-supply = <®_3v3>;
+ DVDD-supply = <®_3v3>;
+ CPVDD-supply = <®_3v3>;
+
+ clocks = <&sck>;
+
+ pll-in = <3>;
+ pll-out = <6>;
+ };
+ };
+
+ ana: ana-reg {
+ compatible = "pwm-regulator";
+
+ regulator-name = "ANA";
+
+ pwms = <&pwm0 2 1000 PWM_POLARITY_INVERTED>;
+ pwm-dutycycle-unit = <1000>;
+ pwm-dutycycle-range = <100 1000>;
+
+ regulator-min-microvolt = <2000000>;
+ regulator-max-microvolt = <20000000>;
+ regulator-ramp-delay = <1000>;
+ };
+
+ sound {
+ compatible = "axentia,tse850-pcm5142";
+
+ axentia,ssc-controller = <&ssc0>;
+ axentia,audio-codec = <&codec>;
+
+ axentia,add-gpios = <&pioA 8 GPIO_ACTIVE_LOW>;
+ axentia,loop1-gpios = <&pioA 10 GPIO_ACTIVE_LOW>;
+ axentia,loop2-gpios = <&pioA 11 GPIO_ACTIVE_LOW>;
+
+ axentia,ana-supply = <&ana>;
+ };
