The above binding was written by me in txt, while the mtd one is
authored by Masami Hiramatsu. I will change this to yaml in the next
version.

Why is this in txt file when mtd one is in yaml.
doc/device-tree-bindings/firmware/uboot,fwu-mdata-mtd.yaml

Thanks,

[PATCH v5 01/23] dt/bindings: Add bindings for FWU Metadata storage device

[Sughosh Ganu]

Add bindings needed for accessing the FWU metadata partitions. These
include the compatible string which point to the access method and the
actual device which stores the FWU metadata.

The current patch adds basic bindings needed for accessing the
metadata structure on GPT partitioned block devices.

+FWU Metadata Access Devicetree Binding
+
+The FWU Multi Bank Update feature uses a metadata structure, stored on
+a separate partition for keeping information on the set of updatable
+images. The device tree node provides information on the storage
+device that contains the FWU metadata.
+
+Required properties :
+
+- compatible : "u-boot,fwu-mdata-gpt";
+- fwu-mdata-store : should point to the storage device which contains
+   the FWU metadata partition.
+
+Example :
+   fwu-mdata {
+   compatible = "u-boot,fwu-mdata-gpt";
+   fwu-mdata-store = <&sdmmc1>;
+   };
