Hi Helen,

Thanks for your work.

I tested this change with the driver merged in the media-tree and it 
works as expected, great work! I have some small nits bellow but other 
then that I think it's ready to go.

When testing this I was unable to locate any up-to-date patches updating 
devicetree files to the state of the driver in staging and had to hack 
something of my own to get it working. Is there patches somewhere? Is  
their a plan to upstream the DT changes for Scarlet ?

I would split the changes to the capture script in it's own patch.
