[PATCH 0/8] ARM: dts: renesas: Add PMU device nodes

[Geert Uytterhoeven]

	Hi Simon, Magnus,

This patch series enables support for the ARM Performance Monitor Units
in Cortex-A7, Cortex-A9, and Cortex-A15 CPU cores on Renesas RZ/A1,
R-Car Gen2, and RZ/G1 SoCs.  This allows for better performance analysis
using the "perf" tool.

Sample output of "perf stat echo" on r8a7791/koelsch:

  - Before:

Still missing:
  - R-Mobile APE6 (no PMU interrupt documented),
  - R-Car M1A and H1 (the PMU interrupt seems to be routed to the legacy
    SH INTC only?),
  - RZ/G1C (SMP support not yet upstream).

This has been tested on r8a7791/koelsch, and boot-tested on
r7s72100/genmai, r8a7790/lager, r8a7792/blanche, and r8a7794/silk.

Thanks!

[PATCH 8/8] ARM: dts: r8a7745: Add PMU device node

[Geert Uytterhoeven]

Enable support for the ARM Performance Monitor Units in the Cortex-A7
CPU cores on RZ/G1E by adding a device node for the PMU.

New Linux output:

    hw perfevents: enabled with armv7_cortex_a7 PMU driver, 5 counters available
