i.MX95 has a more precise counting capability than i.MX93. This will add
a compatible for it.

2.34.1
i.MX95 has a DDR PMU which is almostly same as i.MX93, it now supports
read beat and write beat filter capabilities. This will add support for
i.MX95 and enhance the driver to support specific filter handling for it.
Usage:
For read beat:
~# perf stat -a -I 1000 -e imx9_ddr0/eddrtq_pm_rd_beat_filt2,counter=3,axi_mask=ID_MASK,axi_id=ID/
~# perf stat -a -I 1000 -e imx9_ddr0/eddrtq_pm_rd_beat_filt1,counter=4,axi_mask=ID_MASK,axi_id=ID/
~# perf stat -a -I 1000 -e imx9_ddr0/eddrtq_pm_rd_beat_filt0,counter=5,axi_mask=ID_MASK,axi_id=ID/
eg: For edma2: perf stat -a -I 1000 -e imx9_ddr0/eddrtq_pm_rd_beat_filt0,counter=5,axi_mask=0x00f,axi_id=0x00c/
For write beat:
~# perf stat -a -I 1000 -e imx9_ddr0/eddrtq_pm_wr_beat_filt,counter=2,axi_mask=ID_MASK,axi_id=ID/
eg: For edma2: perf stat -a -I 1000 -e imx9_ddr0/eddrtq_pm_wr_beat_filt,counter=2,axi_mask=0x00f,axi_id=0x00c/

It is hard to tell from this comment, but I figure this "more precise
capability" is not an option you can enable, but instead makes the
programming model of this device different to that of the imx93?
Thanks,

Actually, imx95 is compatible with imx93 except AXI ID filter capability.
But for AXI ID filter, imx95 is using different registers and bits from
imx93 for filter configuration. To distinguish them, I need use different
compatible because programming model cannot recognize which device is
running.
compatible = "fsl,imx95-ddr-pmu";
compatible = "fsl,imx95-ddr-pmu", "fsl,imx93-ddr-pmu";
Both above compatible is okay for me. Therefore, "fsl,imx95-ddr-pmu" is needed.

Okay.

...this. If drivers for the imx93 need changes to work on the imx95,
then `compatible = "fsl,imx95-ddr-pmu", "fsl,imx93-ddr-pmu";` cannot be
used. If they will work, with only the new imx95 features being
non-functional, then you can use it.

Yes, it is. When compatible = "fsl,imx95-ddr-pmu", "fsl,imx93-ddr-pmu" is used,
only the new imx95 features is not functional, other basic function works for
both imx95 and imx93.
