31 **Attribute:** ``/config/gpio-consumer/example-name/live``
33 **Attribute:** ``/config/gpio-consumer/example-name/dev_name``
37 The read-only ``dev_name`` attribute exposes the name of the device as it will
42 The ``'live'`` attribute allows to trigger the actual creation of the device
60 **Attribute:** ``/config/gpio-consumer/example-name/con_id/0/key``
62 **Attribute:** ``/config/gpio-consumer/example-name/con_id/0/offset``
64 **Attribute:** ``/config/gpio-consumer/example-name/con_id/0/drive``
66 **Attribute:** ``/config/gpio-consumer/example-name/con_id/0/pull``

70 **Attribute:** ``/config/gpio-consumer/example-name/con_id/0/transitory``
78 The ``'key'`` attribute represents either the name of the chip this GPIO
80 attribute: if its value is >= 0, then ``'key'`` represents the label of the
95 Once the confiuration is complete, the ``'live'`` attribute must be set to 1 in
126 The following debugfs attribute groups will be created:
132 **Attribute:** ``/sys/kernel/debug/gpio-virtuser/$dev_name/gpiod:foo/values``
134 **Attribute:** ``/sys/kernel/debug/gpio-virtuser/$dev_name/gpiod:foo/values_atomic``
141 The ``values_atomic`` attribute works the same as ``values`` but the kernel
