| help |
| Say Y here to add support for the features implemented by the |
| microcontroller on the CZ.NIC's Turris Omnia SOHO router. |
| The features include: |
| - board poweroff into true low power mode (with voltage regulators |
| disabled) and the ability to configure wake up from this mode (via |
| rtcwake) |
| - true random number generator (if available on the MCU) |
| - MCU watchdog |
| - GPIO pins |
| - to get front button press events (the front button can be |
| configured either to generate press events to the CPU or to change |
| front LEDs panel brightness) |
| - to enable / disable USB port voltage regulators and to detect |
| USB overcurrent |
| - to detect MiniPCIe / mSATA card presence in MiniPCIe port 0 |
| - to configure resets of various peripherals on board revisions 32+ |
| - to enable / disable the VHV voltage regulator to the SOC in order |
| to be able to program SOC's OTP on board revisions 32+ |
| - to get input from the LED output pins of the WAN ethernet PHY, LAN |
| switch and MiniPCIe ports |
| To compile this driver as a module, choose M here; the module will be |
| called turris-omnia-mcu. |
