Hi,

As I've been going through my holiday email I found that Goodix has
released a new datasheet (datasheet rev 0.6 from 2020-12-11) where
this moves from 120 ms to 180 ms.  Sigh.

I'm hoping that we can just land it with the 120 though and then I'll
send a follow-up patch to change to 180.  This will avoid spamming
everyone with a v9 of the patch series.  Please yell if there are any
objections to that plan.  I'd also be fine if you wanted to just
change it to 180 when landing it.

Thanks much!
