Thanks, I have applied the following:
From: Sergei Shtylyov <sergei.shtylyov@xxxxxxxxxxxxxxxxxx>
Subject: [PATCH] arm64: dts: renesas: r8a77980: add SMP support
Add the device nodes for 3 more Cortex-A53 CPU cores; adjust the interrupt
delivery masks for the ARM GIC and Architectured Timer.
Based on the original (and large) patch by Vladimir Barinov.
