[PATCH 21/23] arm: dts: k3-am642-r5-evm: Use am642-evm.dts and k3-am642-evm-u-boot.dtsi

Nishanth Menon
2023-04-14T08:00:33Z

Use am642-evm.dts to represent the Board and selectively
enable/override the configurations necessary. And since
am642-evm-u-boot.dtsi also needs to setup common properties, instead
of re-inventing everything, just reuse the definitions.
