drivers/perf: imx_ddr: Add DDR performance counter support to perf
Add DDR performance monitor support for iMX8QXP. The PMU consists of 3
programmable event counters and a single dedicated cycle counter.
Example usage:
$ perf stat -a -e \
imx8_ddr0/read-cycles/,imx8_ddr0/write-cycles/,imx8_ddr0/precharge/ ls
- or -
$ perf stat -a -e \
imx8_ddr0/cycles/,imx8_ddr0/read-access/,imx8_ddr0/write-access/ ls
Other events are supported, and advertised via perf list.
