| menuconfig CZNIC_PLATFORMS |
| bool "Platform support for CZ.NIC's Turris hardware" |
| 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. |

| config TURRIS_OMNIA_MCU_TRNG |
| 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. |
