From: Yicong Yang <yangyicong@xxxxxxxxxxxxx>

Support new version of DDRC/SLLC PMU identified with updated ACPI HID and
register definition. In order to support this, we do a preliminary refactor
to initialize device of each version by using driver data of each HID
rather than checking the version. This will also make the driver easier to
maintain and extend, since only the HID specific information along
with the new HID will be added to support the new version without touching
the common logic.

Two new Uncore PMU drivers is also added to support the monitoring the
events of the system bus (by NoC PMU) and the DVM opertaions (by MN PMU).

Junhao He (7):
drivers/perf: hisi: Extend struct hisi_pmu_dev_info
drivers/perf: hisi: Simplify the probe process for each DDRC version
drivers/perf: hisi: Add support for HiSilicon DDRC v3 PMU driver
drivers/perf: hisi: Use ACPI driver_data to retrieve SLLC PMU
information
drivers/perf: hisi: Add support for HiSilicon SLLC v3 PMU driver
drivers/perf: hisi: Relax the event number check of v2 PMUs
drivers/perf: hisi: Add support for HiSilicon MN PMU driver

Yicong Yang (2):
drivers/perf: hisi: Support PMUs with no interrupt
drivers/perf: hisi: Add support for HiSilicon NoC PMU
