The patches should be prefixed like 'arm64: dts: ...'.

What does the suffix number '1' mean here?

The bindings/soc/fsl/bman-portals.txt says: Must include
"fsl,bman-portal-<hardware revision>".

> +		reg = <0x0 0x4000 0x4000000 0x4000>;

Can we write it in the same way how the example in the bindings doc
does? 

	reg = <0x0 0x4000>, <0x4000000 0x4000>;

It's more obvious to tell that it has two memory regions.

> +		interrupts = <0 173 0x4>;

Can we use GIC_SPI and IRQ_TYPE_LEVEL_HIGH which are defined by
headers in include/dt-bindings/interrupt-controller/ to make it more
readable?

Will be removed, was used to differentiate between different revisions
on PPC, inherited from there.

This is satisfied by device tree fix-ups performed by the bootloader
adding the correct version. I'll introduce a comment about this here.
