| Date: September 2024 |
| KernelVersion: 6.11 |
| Contact: Marek Behún <kabel@kernel.org> |
| 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. |
| |
| Only available if board information is burned in the MCU (older |
| revisions have board information burned in the ATSHA204-A chip). |

| Date: September 2024 |
| KernelVersion: 6.11 |
| Contact: Marek Behún <kabel@kernel.org> |
| 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. |

| Date: September 2024 |
| KernelVersion: 6.11 |
| Contact: Marek Behún <kabel@kernel.org> |
| 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. |
| |
| This file configures whether front button power on is enabled. |
| |
| This file is present only if the power off feature is supported |
| by the firmware. |

| Description: (RO) Newer versions of the microcontroller firmware report the |
| features they support. These can be read from this file. If the |
| MCU firmware is too old, this file reads 0x0. |
