 @deffn {Interface Driver} {linuxgpiod}
-Linux provides userspace access to GPIO through libgpiod since Linux kernel version v4.6.
-The driver emulates either JTAG or SWD transport through bitbanging.

-@deffn {Config Command} {linuxgpiod gpiochip} @var{chip}
-Set the GPIO chip number for all GPIOs used by linuxgpiod. If GPIOs use
-different GPIO chips then the individual GPIO configuration commands (i.e., not
-@command{linuxgpiod jtag_nums} or @command{linuxgpiod swd_nums}) can be used to
-set chip numbers independently for each GPIO.

-be specified to enable JTAG transport. These pins can also be specified
-individually.

+Linux provides userspace access to GPIO through libgpiod since Linux kernel
+version v4.6. The driver emulates either JTAG or SWD transport through
+bitbanging. There are no driver-specific commands, all GPIO configuration is
+handled by the generic command @ref{adapter gpio, @command{adapter gpio}}. This
+driver supports the resistor pull options provided by the @command{adapter gpio}
+command but the underlying hardware may not be able to support them.
