From 59c433df0378f573a9928a8c94573fdf570138a6 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/4] arm64: dts: r8a7795: 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.
