[PATCH 12/23] arm: dts: k3-am642-r5-sk: Use am642-sk.dts and k3-am642-sk-u-boot.dtsi

Nishanth Menon
2023-04-14T08:00:57Z

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