Hi Nishanth,

The maintainers have picked up the driver and bindings, as follows:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?=
id=3D29057cc5bddc785ea0a11534d7ad2546fa0872d3

Do you have time to work on the "DONOTMERGE" dts patch?

I guess I should be explicit about this: Lets keep this dts patch as "DONOT=
MERGE" in subject line for driver subsystem maintainer (I don't want a repe=
at of cpufreq maintainers picking up dts and associated warnings that are n=
ow pending fixes), resubmit at next rc1 and I can queue up the dts once the=
 maintainers pick up the driver and bindings.
