This is a [3/3] in a series, so presumably it depends on something, so I guess
it should be applied along with the thing it depends on. Right?

The other two are dts parts [1] [2], they have been taken to
arm-soc by Heiko.
And Heiko also gave a Reviewed-by for this patch in v1[3].
[1] https://patchwork.kernel.org/patch/9915139/
[2] https://patchwork.kernel.org/patch/9915145/

So please ask Viresh for an ACK on this one and route it through
arm-soc as well.
Thanks,
