Texas Instruments TAS5805M audio amplifier The TAS5805M serial control bus communicates through I2C protocols. Required properties: - compatible: "ti,tas5805m". - reg: 7-bit I2C address. - gpio,pdn: A GPIO spec to define which pin is connected to the chip's active-low power down pin. Optional properties: - gpio,hpd: GPIO used to detect external interrupt event. If specified, the driver will mute tas5805m if this GPIO is high. Unmute if this GPIO is low. Example: tas5805m@2d { compatible = "ti,tas5805m"; reg = <0x2d>; gpio,pdn = <&tlmm 127 0>; interrupt-parent = <&tlmm>; interrupts = <32 0>; gpio,hpd = <&tlmm 32 0>; pinctrl-names = "default"; pinctrl-0 = <&spkr_2_sd_n_sleep &line_out_hpd_default>; }; For more product information please see the link below: https://www.ti.com/product/TAS5805M
