That driver does not exist in upstream or -next. Looks like this is a
patch from some downstream tree, which you should not use as base for
sending patches upstream.

It seems you need to send patches for the entire driver + bindings.

Sorry, my bad, I should have read the cover letter, which mentions the
dependency on https://patchwork.kernel.org/project/linux-arm-msm/list/?series=505483&archive=both&state=*

Can this be const struct lpg_channel_data? I think that will move it to
rodata which is only a good thing.

I agree.
@Bjorn, can we make it const struct?

I like it and have updated the driver patches accordingly.


Seems like I still have a couple of more comments from Uwe left to
resolve on v9 of the driver, I'll fix those up and post the driver
again.

Thanks,
