- menuconfig CZNIC_PLATFORMS
- bool "Platform support for CZ.NIC's Turris hardware"
- depends on ARCH_MVEBU || COMPILE_TEST
- help
- Say Y here to be able to choose driver support for CZ.NIC's Turris
- devices. This option alone does not add any kernel code.
- if CZNIC_PLATFORMS
- config TURRIS_OMNIA_MCU
- tristate "Turris Omnia MCU driver"
- depends on MACH_ARMADA_38X || COMPILE_TEST
- depends on I2C
- help
- Say Y here to add support for the features implemented by the
- microcontroller on the CZ.NIC's Turris Omnia SOHO router.
- 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.

- bool "Turris Omnia MCU GPIOs"
- default y
- depends on GPIOLIB
- depends on OF
- select GPIOLIB_IRQCHIP
- help
- Say Y here to add support for controlling MCU GPIO pins and receiving
- MCU interrupts on CZ.NIC's Turris Omnia.
- This enables you 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),
- - enable / disable USB port voltage regulators and to detect USB
- overcurrent,
- - detect MiniPCIe / mSATA card presence in MiniPCIe port 0,
- - configure resets of various peripherals on board revisions 32+,
- - enable / disable the VHV voltage regulator to the SOC in order to be
- able to program SOC's OTP on board revisions 32+,
- - get input from the LED output pins of the WAN ethernet PHY, LAN
- switch and MiniPCIe ports.
- config TURRIS_OMNIA_MCU_SYSOFF_WAKEUP
- bool "Turris Omnia MCU system off and RTC wakeup"
- default y
- depends on RTC_CLASS
- help
- Say Y here to add support for CZ.NIC's Turris Omnia board poweroff
- into true low power mode (with voltage regulators disabled) and the
- ability to configure wake up from this mode (via rtcwake).
- config TURRIS_OMNIA_MCU_WATCHDOG
- bool "Turris Omnia MCU watchdog"
- default y
- depends on WATCHDOG
- select WATCHDOG_CORE
- help
- Say Y here to add support for watchdog provided by CZ.NIC's Turris
- Omnia MCU.

- bool "Turris Omnia MCU true random number generator"
- default y
- depends on TURRIS_OMNIA_MCU_GPIO
- depends on HW_RANDOM=y || HW_RANDOM=TURRIS_OMNIA_MCU
- help
- Say Y here to add support for the true random number generator
- provided by CZ.NIC's Turris Omnia MCU.
