This CLKIN is used by the PLL 19 internal 1.8MHz. This CLKIN is used by the PLL. In addition to PLL, the PDM 20 reference clock is also selectable: PLL, IVCLK 20 reference clock is also selectable: PLL, IVCLKIN, BCLK or MCLK. 21 For system integration the dt-bindings/sound/t 21 For system integration the dt-bindings/sound/tas2552.h header file provides 22 defined values to select and configure the PLL 22 defined values to select and configure the PLL and PDM reference clocks. 23 23 24 Example: 24 Example: 25 25 26 tas2552: tas2552@41 { 26 tas2552: tas2552@41 { 27 compatible = "ti,tas2552"; 27 compatible = "ti,tas2552"; 28 reg = <0x41>; 28 reg = <0x41>; 29 vbat-supply = <®_vbat>; 29 vbat-supply = <®_vbat>; 30 iovdd-supply = <®_iovdd>; 30 iovdd-supply = <®_iovdd>; 31 avdd-supply = <®_avdd>; 31 avdd-supply = <®_avdd>; 32 enable-gpio = <&gpio4 2 GPIO_ACTIVE_HI 32 enable-gpio = <&gpio4 2 GPIO_ACTIVE_HIGH>; 33 }; 33 }; 34 34 35 For more product information please see the li 35 For more product information please see the link below: 36 https://www.ti.com/product/TAS2552 36 https://www.ti.com/product/TAS2552
