ARM: dts: r8a7790: Add PMU device nodes
Enable support for the ARM Performance Monitor Units in the Cortex-A15
and Cortex-A7 CPU cores on R-Car H2 by adding device nodes for the two
PMUs.
New Linux output:
hw perfevents: enabled with armv7_cortex_a15 PMU driver, 7 counters available
hw perfevents: /pmu-1: failed to probe PMU!
hw perfevents: /pmu-1: failed to register PMU devices!
The last two lines are due to the Cortex-A7 CPU cores being described in
DT, but not enabled by the firmware.
