From 59c433df0378f573a9928a8c94573fdf570138a6 Mon Sep 17 00:00:00 2001 From: Gaku Inami Date: Wed, 15 Nov 2017 11:28:32 +0900 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.
