From 09f49bcf6f5a62467f4fcda59d6bc38f24d97c36 Mon Sep 17 00:00:00 2001 From: Biju Das Date: Thu, 23 Aug 2018 14:43:05 +0100 Subject: [PATCH] arm64: dts: renesas: r8a774a1: Add Cortex-A53 CPU cores This patch adds definitions for L2 cache for the Cortex-A53 CPU cores (512 KiB in size, organized as 32 KiB x 16 ways), adds Cortex-A53 CPU cores (setting a total of 6 cores, 2 x Cortex-A57 + 4 x Cortex-A53), and finally enables the performance monitor unit for the Cortex-A53 cores on the R8A774A1 SoC. Based on work done for r8a7796 SoC.
