ASoC: add TA5720 digital amplifier DT bindings The Texas Instruments TAS5720L/M device is a high-efficiency mono Class-D audio power amplifier optimized for high transient power capability to use the dynamic power headroom of small loudspeakers. Its digital time division multiplexed (TDM) interface enables up to 16 devices to share the same bus.

Texas Instruments TAS5720 Mono Audio amplifier
The TAS5720 serial control bus communicates through the I2C protocol only. The
serial bus is also used for periodic codec fault checking/reporting during
audio playback. For more product information please see the links below:
ASoC: Replace HTTP links with HTTPS ones Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

Required properties:
ASoC: tas5720: add basic support for TAS5722 devices The TI TAS5722 digital amplifier is very similar to the TAS5720 from an overall and register map perspective. Therefore the existing driver can be extended easily to support this additional device. This commit allows TAS5722 devices to be used in a "subset" type of fashion, without exposing any of the additional features they offer.

- reg : I2C slave address
- dvdd-supply : phandle to a 3.3-V supply for the digital circuitry
- pvdd-supply : phandle to a supply used for the Class-D amp and the analog
Example:
tas5720: tas5720@6c {
compatible = "ti,tas5720";
reg = <0x6c>;
dvdd-supply = <&vdd_3v3_reg>;
pvdd-supply = <&amp_supply_reg>;
