The RZ/A2 uses a modified SCIF that until recently was only used in
Renesas MCU devices (not MPU devices).
So, while it functions mostly the same as a normal SCIF, some things
needed to be shifted around.
In the end, a standard compatible = "renesas,scif" is all that is really
needed (not a SoC specific "renesas,scif-r7s9210").
Becase there is no device tree yet, here is sample of what it would
look like:
scif0: serial@e8007000 {
compatible = "renesas,scif-r7s9210", "renesas,scif";
reg = <0xe8007000 18>;
interrupts = <GIC_SPI 265 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 266 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 267 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 265 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 268 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 268 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&mstp4_clks R7S9210_CLK_SCIF0>;
clock-names = "fck";
power-domains = <&cpg_clocks>;
status = "disabled";
};
