The led GPIOs will be active-high, while the power GPIO will be active-low (i.e.
|

gpiod_is_active_low(power) will be true).
|
||||
|
||||
The second parameter of the gpiod_get() functions, the con_id string, has to be
|

the <function>-prefix of the GPIO suffixes ("gpios" or "gpio", automatically
|

looked up by the gpiod functions internally) used in the device tree. With above
|
||||
"led-gpios" example, use the prefix without the "-" as con_id parameter: "led".
|

|

Internally, the GPIO subsystem prefixes the GPIO suffix ("gpios" or "gpio")
|
||||
with the string passed in con_id to get the resulting string
|

(snprintf(... "%s-%s", con_id, gpio_suffixes[]).

Since the "power" GPIO is mapped as active-low, its actual signal will be 0

property is handled during mapping and is thus transparent to GPIO consumers.

Since the "led" GPIOs are mapped as active-high, this example will switch their

signals to 1, i.e. enabling the LEDs. And for the "power" GPIO, which is mapped

as active-low, its actual signal will be 0 after this code. Contrary to the legacy

integer GPIO interface, the active-low property is handled during mapping and is
