Looks like some of the STi files are a little wavering on convention,
but I suggest the extra '\n's are superfluous.

This should be a device type, not a model number.

To the uninitiated c8sectpfe is pretty indecipherable.
How about *-c8sectpfe-demod?

Please use the predetermined DEFINES for the flags cell.

I would put *-names *under* the properties they pertain to and in the
same format i.e. one per line in this case, for easy eye-match.

Why the '\n'?

If you are adding this property, I would get Wolfram or one of the DT
guys to Ack it.

Why not use the whole name "reset"?
"-gpio" should be "-gpios".
So, in full: "reset-gpios"?
Flags: GPIO_ACTIVE_HIGH ?
