Thanks for your patch! > Signed-off-by: Gaku Inami <[email protected]> Reviewed-by: Geert Uytterhoeven <[email protected]> 411 for the A53 cores sounds a bit low to me, though. Documentation/devicetree/bindings/arm/cpu-capacity.txt uses 578. Perhaps you already took into account the maximum clock frequencies? According to the binding document, you should not do that (cfr. "final capacities are 1024 for cluster0 and 446 for cluster1" in the bindings doc). > --- a/arch/arm64/boot/dts/renesas/r8a7795.dtsi > +++ b/arch/arm64/boot/dts/renesas/r8a7795.dtsi > @@ -123,6 +127,7 @@ > enable-method = "psci"; > clocks =<&cpg CPG_CORE R8A7795_CLK_Z2>; > operating-points-v2 = <&cluster1_opp>; > + capacity-dmips-mhz = <411>; > }; Gr{oetje,eeting}s, Geert -- Geert Uytterhoeven -- There's lots of Linux beyond ia32 -- [email protected] In personal conversations with technical people, I call myself a hacker.
