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
+ This option only enables the core part of the driver. Specific
+ features can be enabled by subsequent config options.
To compile this driver as a module, choose M here; the module will be
called turris-omnia-mcu.
