From b3e079ba90ed7ee0e618a441844f3274c6e49e3b Mon Sep 17 00:00:00 2001

Subject: [PATCH 4/4] arm64: Update the energy model on CA53 for R-Car Gen3
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 will support with cpu capacity
features.
