The "renesas,scif" compatible value is currently used for the SCIF variant in all Renesas SoCs of the R-Car and RZ families. However, the variant used in the RZ family is not the common "SH-4(A)" variant, but the "SH-2(A) with FIFO data count register" variant, as it has the "Serial Extension Mode Register" (SCEMR), just like on sh7203, sh7263, sh7264, and sh7269. Use the (already documented) SoC-specific "renesas,scif-r7s72100" compatible value to differentiate. The "renesas,scif" compatible value can still be used as a common denominator for SCIF variants with the "SH-4(A)" register layout (i.e. ignoring the SCEMR register). Note that currently both variants are treated the same, but this may change if support for the SCEMR register is ever added.
