Re: [PATCH 3/3] input: gpio_keys: Make use of the device property API

[sergk sergk2mail <sergk.admin@xxxxxxxxx>]

Sorry to interrupt with question, but I guess this thread has right
people for related to this topic question.
The question is reversed to the topic - how to, having working touch
driver in Android and Windows determine which exactly gpio pin is used
as INT\WAKE gpio by the driver?
Or for example even when I have some variant of such gpio pin how to
ensure that it is exactly this gpio?
For example practical task: I am trying to determine which exactly
gpio pin is responsible for INT/WAKE touchscreen on Chuwi Vi10
(baytrail x86_64 Arch 4.4.2 vanilla kernel with my custom config).
Exploring /sys/class/gpio/* have guessed that in Android it is
probably gpio134 but in Linux 4.4.2 probably gpio393. How to compare
such pins and ensure that in Linux 393 gpio is the same as 134 in
Android?
Is this possible to do in any predictable (not guessing or enumerating
all range) way?

Regards and thanks for replies,
                                                 Serge Kolotylo.
