ASoC: Updates for v4.10

There's been a few bits of framework work this time around and quite a lot of cleanups and improvements to existing code: - Support for stereo DAPM controls from Chen-yu Tsai. - Some initial work on the of-graph sound card from Morimoto-san, the main bulk of this is currently in binding review. - Lots of Renesas cleanups from Morimoto-san and sunxi work from Chen-yu Tsai. - regmap conversions of the remaining AC'97 drivers from Lars-Peter Clausen. - A new version of the topology ABI from Mengdong Lin. - New drivers for Cirrus Logic CS42L42, Qualcomm MSM8916-WCD, and Realtek RT5665. -----BEGIN PGP SIGNATURE----- iQFHBAABCAAxFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAlhO62YTHGJyb29uaWVA a2VybmVsLm9yZwAKCRAk1otyXVSH0H6eB/9yhC3kyWNissnPZ7S9iY8b5J8NGVpW y5RQz4/ngD/H949z6WXbYo8jPWH9cpkr64ED68TsJ8CPUdJXEZAgC91yjgrrq0W6 9es76Y8SCjwx7kuxs4Vzi7oJNY7Srca7NmUHfrFIAu8+vV88U731RKsF6TR1yT1I 6W4FZnetHNVcuFf4Di66cxntgJt/wD2s06TPpLLDjs1AqZSIhfFDIsCOSuvldcoX clr/zEHVzh4gJV36JGDPvxDjjK5dqL/j1X3VlLSKlZYmzW4WK44patXVVhmZkhns tfi1RaXAWE/LmiJJ6pmgrpdCIsQJqZp2nkdRZ+pF52b2QfXDv2gI1Bcy =Gsj0 -----END PGP SIGNATURE----- Merge tag 'asoc-v4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Updates for v4.10 There's been a few bits of framework work this time around and quite a lot of cleanups and improvements to existing code: - Support for stereo DAPM controls from Chen-yu Tsai. - Some initial work on the of-graph sound card from Morimoto-san, the main bulk of this is currently in binding review. - Lots of Renesas cleanups from Morimoto-san and sunxi work from Chen-yu Tsai. - regmap conversions of the remaining AC'97 drivers from Lars-Peter Clausen. - A new version of the topology ABI from Mengdong Lin. - New drivers for Cirrus Logic CS42L42, Qualcomm MSM8916-WCD, and Realtek RT5665.

+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,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
+            \                /

+
+   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.
