After comparing CPU core performance over a wide range of SoCs, I had been wondering for a long time why DMIPS/MHZ for the Cortex-A15 CPU cores on R-Mobile APE6 is slightly higher than on R-Car Gen2 SoCs. It turned out to be untrue, as the R-Mobile APE6 DTS contains a wrong crystal osciallator freqency, causing the CPU cores on R-Mobile APE6 to run 4% faster than assumed by Linux. The first patch fixes this. The two other patches contain small improvements and a small fix, none of which have any functional impact. I plan to queue this in renesas-devel for v6.9. Thanks for your comments!
