Question: the status for SMMUv2 PMU driver

[Leo Yan]

Hi Will, Robin,

[ + Arm mailing list ]

Linux mainline kernel has supported SMMUv3 PMU with the driver
drivers/perf/arm_smmuv3_pmu.c, but it misses to support SMMUv2 PMU
driver.

So I want to confirm if there have any existed SMMUv2 PMU driver
can be referred, or if any block issue for upstreaming SMMUv2
driver?  Thank you for suggestions and insights.
