Rodolfo, currently data->capture_clear is false by default, and there
is no way of setting it in the pps-gpio driver.
How would you suggest setting it?

I think that driver needs a review... in fact, by using gpiod_*() functions we should be able to remove both assert_falling_edge and capture_clear flags.

Will it be OK to setting PPS_WIDTHASSERT by default?

I think they can both be asserted by default. Why should someone may prefer to disable one of them?

Ciao,

Rodolfo
