Hi Kumar,

Here are the device tree bindings for the TPS65219: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/Documentation/devicetree/bindings/regulator/ti,tps65219.yaml?h=ti-linux-6.1.y

Here are two examples of implementations for different AM62 boards.

AM625 Beagleplay: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/arch/arm64/boot/dts/ti/k3-am625-beagleplay.dts?h=ti-linux-6.1.y#n712

SK-AM62-LP: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/arch/arm64/boot/dts/ti/k3-am62-lp-sk.dts?h=ti-linux-6.1.y#n151
