+Subject: [PATCH] arm64: dts: ls2081ardb: Add DTS support for NXP LS2081ARDB
+
+This patch add support for NXP LS2081ARDB board which has
+LS2081A SoC.
+
+LS2081A SoC is 40-pin derivative of LS2088A SoC
+So, from functional perspective both are same.
+Hence,ls2088a SoC dtsi files are included from ls2081ARDB dts
