When I look at the platform documentation I get the impression that this
should be: <0 480 94>, <94 609 32>;

Can you confirm that the last signal is correctly described?

Hi Bjorn,

Thanks for your review.

Yes, I confirmed by double checking the entries in downstream 'pdc-sm8150.c'.
The pdc pins in the 2nd range start from 94 and end at 124, so a total
of 31 entries, but both 94 and 124 pins included.

Or, am I missing something?

Thanks,
Bhupesh
