[PATCH v2 0/2] arm64: dts: r8a7795: FCPF and FDP1 device nodes

[Kieran Bingham]

Hi Simon,

Here is my updated series for the dts updates in relation to the RCar/FDP1.

The fcpf patch has collected a reviewed-by from Geert, whilst the fdp1
patch has collected a reviewed by from both Laurent and Geert, with a
small change to remove the labels, as they will not be referenced.

You responded to my previous set for these with the following comment:

> These patches look good to me. My assumption is that they

Your assumption was correct, and they could be applied without breakage.

RobH has acked the binding for the RCar FCPF, but I have not seen an ack for
the FDP1 binding yet. I'll follow that up, and ping you on the fdp1 dts patch
when it resolved.

Regards

Kieran

Hi Simon,

The bindings for this have now been acked by RobH.

Thanks, I have queued these up for v4.9.

There was a small amount of fuzz when applying the first patch,
please check to make sure it has been applied correctly once
it hits the devel branch of the renesas tree.
