Hi,
I missing some functionality in the current GPIO interface which I am using in an
embedded environment.
It is not possible to specify if an output is low or high active on arch level.
IOW I want to activate or deactivate (on driver level) an output without having
to know if an output is high or low active, which should be specified on arch level.
Currently I created a structure with the gpio number and a boolean is_inverted,
and I added two functions called gpio_activate and gpio_deactivate, these
functions allow me to control the hardware independent of the low level
implementation, for example gpio_activate(RESET).
My question is if there is already such an solution or will the GPIO interface
support this functionality in the future?
Best regards,
Niels Langendorff
