Ok. In the next version I will update the bindings like below

-title: Microchip MPFS {Q,}SPI Controller Device Tree Bindings
+title: Microchip FPGA {Q,}SPI Controllers
+
+description:
+  SPI and QSPI controllers on the Microchip PolarFire SoC and they are based
+ on the "soft"  fabric IP cores.
 oneOf:
       - items:
+          - const: microchip,mpfs-qspi
+          - const: microchip,coreqspi-rtl-v2
+      - const: microchip,coreqspi-rtl-v2
       - const: microchip,mpfs-spi

Is that ok?

Thanks,
