Do you have a link to the binding documentation for this? I'm still in
the dark re: why there's a need for #calibrate-cells at all. It seems
like this should be some internal implementation detail of the Tegra
DC/..., or implicit based on the compatible value (if cell count
changes, just rev the compatible value; it's not like this is a generic
service for loosely coupled drivers).
