drivers/perf: add DDR Sub-System Driveway PMU driver for Yitian 710 SoC
Add the DDR Sub-System Driveway Performance Monitoring Unit (PMU) driver
support for Alibaba T-Head Yitian 710 SoC chip. Yitian supports DDR5/4
DRAM and targets cloud computing and HPC.
Each PMU is registered as a device in /sys/bus/event_source/devices, and
users can select event to monitor in each sub-channel, independently. For
example, ali_drw_21000 and ali_drw_21080 are two PMU devices for two
sub-channels of the same channel in die 0. And the PMU device of die 1 is
prefixed with ali_drw_400XXXXX, e.g. ali_drw_40021000.
Due to hardware limitation, one of DDRSS Driveway PMU overflow interrupt
shares the same irq number with MPAM ERR_IRQ. To register DDRSS PMU and
MPAM drivers successfully, add IRQF_SHARED flag.
