Subject: Re: [PATCH v4 06/19] dt-bindings: media: i2c: max96717: add support
 for MAX96793

Hi Cosmin,

I'm preparing a test with Alvium + max96717 + max96716. I can't see away 
to overwrite cfg settings to force pixel mode or tunnel mode. Any plans 
to add this? Sometimes it is required to force the other mode than set 
by pin-strapping.
