Roger,

The existing hierarchy prior to this series is as follows:
k3-am62p.dtsi = k3-am62p-main.dtsi + k3-am62p-mcu.dtsi +
		k3-am62p-wakeup.dtsi + k3-am62p-thermal.dtsi + <delta-1>
k3-am62p5.dtsi = k3-am62p.dtsi + <delta-2>
k3-j722s.dtsi = k3-am62p5.dtsi + <delta-3>
k3-j722s-evm.dts = k3-j722s.dtsi + <detla-4>

Based on your suggestion, you seem to propose the following hierarchy:
k3-am62p-{main,mcu,thermal,wakeup}.dtsi = AM62P specific data
k3-am62p.dtsi = k3-am62p-j722s-common-main.dtsi +
		k3-am62p-j722s-common-mcu.dtsi +
		k3-am62p-j722s-common-wakeup.dtsi +
		k3-am62p-j722s-common-thermal.dtsi +
		k3-am62p-{main,mcu,thermal,wakeup}.dtsi +
		<delta-5>
k3-am62p5.dtsi = k3-am62p.dtsi + <delta-2>
k3-j722s-{main,mcu,thermal,wakeup}.dtsi = J722S specific data
k3-j722s.dtsi = k3-am62p-j722s-common-main.dtsi +
		k3-am62p-j722s-common-mcu.dtsi +
		k3-am62p-j722s-common-wakeup.dtsi +
		k3-am62p-j722s-common-thermal.dtsi +
		k3-j722s-{main,mcu,thermal,wakeup}.dtsi +
		<delta-6>
k3-j722s-evm.dts = k3-j722s.dtsi + <delta-4>

Please let me know whether the above organization of files matches what you
expect it to look like. I will post the v6 series based on your feedback.

Regards,
Siddharth.
