Use double backticks instead of quotes for sysfs attribute value.
This makes sphinx generate the "mcu" and "cpu" values in monospace when
rendering to HTML.

Description: (RO) Contains device first MAC address. Each Turris Omnia is
|
|
allocated 3 MAC addresses. The two additional addresses are
|
|
computed from the first one by incrementing it.
|

|
|
Description: (RW) The front button on the Turris Omnia router can be
|
|
configured either to change the intensity of all the LEDs on the
|
|
front panel, or to send the press event to the CPU as an
|
|
interrupt.
|
|
|
|
This file switches between these two modes:
|
|
- ``mcu`` makes the button press event be handled by the MCU to
|
|
change the LEDs panel intensity.
|
|
- ``cpu`` makes the button press event be handled by the CPU.

|
|
Description: (RW) Newer versions of the microcontroller firmware of the
|
|
Turris Omnia router support powering off the router into true
|
|
low power mode. The router can be powered on by pressing the
|
|
front button.
|
|
