      arm64: dts: rockchip: update dynamic-power-coefficient for rk3399 · 45a995c0

      This patch updates the dynamic-power-coefficient for big cluster on
      rk3399 SoCs.
      
      The dynamic power consumption of the CPU is proportional to the square of
      the Voltage (V) and the clock frequency (f). The coefficient is used to
      calculate the dynamic power as below -
      Pdyn = dynamic-power-coefficient * V^2 * f
      Where Voltage is in uV, frequency is in MHz.
      
      As the following is the tested data on rk3399's big cluster.
      frequency(MHz)  Voltage(V)  Current(mA) Dynamic-power-coefficient
      24              0.8         15
      48              0.8         23          ~417
      96              0.8         40          ~443
      216             0.8         82          ~438
      312             0.8         115         ~430
      408             0.8         150         ~455
      So the dynamic-power-coefficient average value is about 436.

      arm64: dts: rockchip: fix include reference · 6bf1c2d2
      Arnd Bergmann authored
      The way we handle include paths for DT has changed a bit, which
      broke a file that had an unconventional way to reference a common
      header file:
      
      arch/arm64/boot/dts/rockchip/rk3399-gru-kevin.dts:47:10: fatal error: include/dt-bindings/input/linux-event-codes.h: No such file or directory
      
      This removes the leading "include/" from the path name, which fixes it.
      
      Fixes: d5d332d3
      
       ("devicetree: Move include prefixes from arch to separate directory")
