+Subject: [PATCH 3/4] arm64: dts: r8a7795-es1: Update cpu capacity-dmips-mhz
+
+Since the cpu_capacity for CA53 was set smaller than expected, the
+behavior of scheduler may not be suitable a little. This patch fixes
+the reasonable value to fit current implementation. This value should
+be updated again when the turbo mode and big little architecture will
+support with cpu capacity features.
