This needs to be
return !gpiod_get_value_raw(ts->gpio_pendown);
There is no such function. The gpio descriptor runpath simply assumes that
device trees can be trusted.
Sorry, this was supposed to be gpiod_get_raw_value():

I looked at various DTSes we have and they use a mix of active high and
active low annotations, so we have to go with the "raw" variant for now,
and then update to normal one once we update bad DTSes.
I just sighed and fixed all the device trees :D
Yeah, we we can land the DT fixes ahead of the driver change that would
be great. Otherwise we need a temporary application of
gpiod_get_raw_value().
