Subject: Re: [PATCH v3 0/2] Improve older camss supply descriptions

btw. I looked at qcom,qcm2290-camss.yaml and if there isn't something 
very specific about qcm2290, the supply may have wrong voltrage.
I'll leave this for someone with datasheets (cc Loic):

   vdd-csiphy-1p8-supply:
     description:
       Phandle to 1.8V regulator supply to CSI PHYs pll block.

as see on the mailing list the 0.8V example was given and changed to 
1.8V, so maybe it has a reason, just making a note to be extra sure 
while touching the docs.
