Not sure these PD id's can be generic and used across all RZ/G2L family
devices and RZ/V2M?

That may be another approach. I chose this one to have everything SoC
specific in a single place. With this, e.g., we can have all the SCIF
related IDs grouped together (as we know from the beginning how many SCIF
blocks a SoC has):

+#define R9A07G044_PD_SCIF0		42
+#define R9A07G044_PD_SCIF1		43
+#define R9A07G044_PD_SCIF2		44
+#define R9A07G044_PD_SCIF3		45
+#define R9A07G044_PD_SCIF4		46

If a single file with all the IDs for all the SoC will be used then, as
every SoC will have a different number of SCIFs, I2Cs, RSPIs, to keep the
DT binding backward compatibility, we will end up with these IDs not being
grouped on functionality, e.g., we may end up with something like:

+#define R9A07G044_PD_I2C0		38
+#define R9A07G044_PD_I2C1		39
+#define R9A07G044_PD_I2C2		40
+#define R9A07G044_PD_I2C3		41
+#define R9A07G044_PD_SCIF0		42
+#define R9A07G044_PD_SCIF1		43
+#define R9A07G044_PD_SCIF2		44
+#define R9A07G044_PD_SCIF3		45
+#define R9A07G044_PD_SCIF4		46
+#define R9A07G044_PD_SCI0		47
+#define R9A07G044_PD_SCI1		48
+#define R9A07G044_PD_IRDA		49
+#define R9A07G044_PD_RSPI0		50
+#define R9A07G044_PD_RSPI1		51
+#define R9A07G044_PD_RSPI2		52
+#define R9A07G044_PD_CANFD		53
+#define R9A07G044_PD_ADC		54
+#define R9A07G044_PD_TSU		55

+#define R9A07G044_PD_SCIF5		56
+#define R9A07G044_PD_SCIF6		57
+#define R9A07G044_PD_I2C4		58
+#define R9A07G044_PD_RSPI3		58
+#define R9A07G044_PD_RSPI4		59

Of course, I can adjust it if Geert wants it differently.

Thank you,
