Subject: Re: [PATCH v5 1/2] ASoC: google: dt-bindings: modify machine bindings
 for two MICs case

Hi Rob,
Could you please kindly review this patch ?

 I had got your "reviewed-by" on v1 patch, the v1 depends on this patch series
(https://patchwork.kernel.org/patch/11773221) at that time.

Now, that patch what I depended (11773221) had made modification and
it was Applied to
   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-next
commit e158d2d83cab ("ASoC: google: dt-bindings: Add sc7180-trogdor
machine bindings")

I noted what I did on cover letter
v2:
- Documentation: Modify the dimc-gpios property description and examples.

That is why I bother you again to review it. Please let me know if
this looks good to you.
Thanks!
