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. -----BEGIN PGP SIGNATURE----- iQFHBAABCgAxFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAl0D6tUTHGJyb29uaWVA a2VybmVsLm9yZwAKCRAk1otyXVSH0DEzB/4gIkIbWlgOEl1S8fNCh2ZkmTSudsof 8Sf8dsM+ZAQgren2sUg0dVpM2t6sc0Aq4OkNoC51VbxhSXM1Cpka3djDMsb59L4Z 74Lok9kA0S4nZ+qlLGh5KK4vFrVI7DAusxkl6vDVghR78T+FDwe5mVAKffYgRUsa pswq8IeYrFk1KocIT3y3BFt7qhiERaPNLUtC2RCPaHjNoWPZHGaPG7Y+fWeoZ8gn blh7FNvSQwiBATEFXpg0pH7ZZHjIHN7pHeCF2ZfnV0pMi0ylYq8bZqM24hbvbHBZ x+16nYtYpQdMJYxR7TJReARUGb/Koi6nHBNv1oulF0lmsiP1JCNwKZwp =4nXg -----END PGP SIGNATURE----- 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";
|
||||
|
||||
[...]
|
||||
|
||||
dai-link-x {
|
||||
sound-dai = <&tdmif_a>;
|
||||
dai-format = "i2s";
|
||||
dai-tdm-slot-tx-mask-0 = <1 1>;
|
||||
|
||||
codec-0 {
|
||||
sound-dai = <&tohdmitx TOHDMITX_I2S_IN_A>;
|
||||
};
|
||||
|
||||
codec-1 {
|
||||
sound-dai = <&external_dac>;
|
||||
};
|
||||
};
|
||||
|
||||
dai-link-y {
|
||||
sound-dai = <&tdmif_c>;
|
||||
dai-format = "i2s";
|
||||
dai-tdm-slot-tx-mask-0 = <1 1>;
|
||||
|
||||
codec {
|
||||
sound-dai = <&tohdmitx TOHDMITX_I2S_IN_C>;
|
||||
};
|
||||
};
|
||||
|
||||
dai-link-z {
|
||||
sound-dai = <&tohdmitx TOHDMITX_I2S_OUT>;
|
||||
|
||||
codec {
|
||||
sound-dai = <&hdmi_tx>;
|
||||
};
