Hi Rob,
How about like this:
diff --git a/Documentation/devicetree/bindings/mtd/fsl-quadspi.txt b/Documentation/devicetree/bindings/mtd/fsl-quadspi.txt
index 00c587b..7a9a523 100644
--- a/Documentation/devicetree/bindings/mtd/fsl-quadspi.txt
+++ b/Documentation/devicetree/bindings/mtd/fsl-quadspi.txt
@@ -4,6 +4,8 @@ Required properties:
- compatible : Should be "fsl,vf610-qspi", "fsl,imx6sx-qspi",
"fsl,imx7d-qspi", "fsl,imx6ul-qspi",
"fsl,ls1021-qspi"
+ Invalid compatible just for SOC flag:
+ "fsl,ls2080a-qspi"
- reg : the first contains the register location and length,
the second contains the memory mapping address and length
- reg-names: Should contain the reg names "QuadSPI" and "QuadSPI-memory"
Thanks for your review.
