Hi all,
This patch series contains fixes and improvements for clock descriptions
of the Renesas R-Mobile APE6 SoC and the APE6-EVM development board.
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!
