Merge tag 'asoc-tohdmitx' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into HEAD
ASoC: tohdmitx bindings The patch on this branch adds bindings for tohdmitx, including a header to be used in DT bindings which needs to be shared with the arm-soc tree in order to allow system DTs to be merged. # gpg: Signature made Fri 14 Jun 2019 11:43:33 AM PDT # gpg: using RSA key ADE668AA675718B59FE29FEA24D68B725D5487D0 # gpg: issuer "broonie@kernel.org" # gpg: Good signature from "Mark Brown <broonie@sirena.org.uk>" [full] # gpg: aka "Mark Brown <broonie@debian.org>" [full] # gpg: aka "Mark Brown <broonie@kernel.org>" [full] # gpg: aka "Mark Brown <broonie@tardis.ed.ac.uk>" [full] # gpg: aka "Mark Brown <broonie@linaro.org>" [unknown] # gpg: aka "Mark Brown <Mark.Brown@linaro.org>" [unknown] * tag 'asoc-tohdmitx' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound: ASoC: meson: add tohdmitx DT bindings

+* Amlogic HDMI Tx control glue

+Required properties:
+- compatible: "amlogic,g12a-tohdmitx"
+- reg: physical base address of the controller and length of memory
+ mapped region.
+- #sound-dai-cells: should be 1.
+
+Example on the S905X2 SoC:
+
+tohdmitx: audio-controller@744 {
+ compatible = "amlogic,g12a-tohdmitx";
+ reg = <0x0 0x744 0x0 0x4>;
+ #sound-dai-cells = <1>;
+};
+
+Example of an 'amlogic,axg-sound-card':
+
+sound {
+ compatible = "amlogic,axg-sound-card";
