7 menuconfig CZNIC_PLATFORMS
8 bool "Platform support for CZ.NIC's Turris hardware"
10 Say Y here to be able to choose driver support for CZ.NIC's Turris
11 devices. This option alone does not add any kernel code.
15 config TURRIS_OMNIA_MCU
16 tristate "Turris Omnia MCU driver"
17 depends on MACH_ARMADA_38X || COMPILE_TEST
20 Say Y here to add support for the features implemented by the
21 microcontroller on the CZ.NIC's Turris Omnia SOHO router.
22 This option only enables the core part of the driver. Specific
23 features can be enabled by subsequent config options.
24 To compile this driver as a module, choose M here; the module will be
25 called turris-omnia-mcu.
29 config TURRIS_OMNIA_MCU_GPIO
30 bool "Turris Omnia MCU GPIOs"
34 select GPIOLIB_IRQCHIP
36 Say Y here to add support for controlling MCU GPIO pins and receiving
37 MCU interrupts on CZ.NIC's Turris Omnia.
39 - get front button press events (the front button can be configured
40 either to generate press events to the CPU or to change front LEDs
42 - enable / disable USB port voltage regulators and to detect USB
44 - detect MiniPCIe / mSATA card presence in MiniPCIe port 0,
45 - configure resets of various peripherals on board revisions 32+,
46 - enable / disable the VHV voltage regulator to the SOC in order to be
47 able to program SOC's OTP on board revisions 32+,
48 - get input from the LED output pins of the WAN ethernet PHY, LAN
49 switch and MiniPCIe ports.
51 config TURRIS_OMNIA_MCU_SYSOFF_WAKEUP
52 bool "Turris Omnia MCU system off and RTC wakeup"
56 Say Y here to add support for CZ.NIC's Turris Omnia board poweroff
57 into true low power mode (with voltage regulators disabled) and the
58 ability to configure wake up from this mode (via rtcwake).
60 config TURRIS_OMNIA_MCU_WATCHDOG
61 bool "Turris Omnia MCU watchdog"
66 Say Y here to add support for watchdog provided by CZ.NIC's Turris
69 config TURRIS_OMNIA_MCU_TRNG
70 bool "Turris Omnia MCU true random number generator"
72 depends on TURRIS_OMNIA_MCU_GPIO
73 depends on HW_RANDOM=y || HW_RANDOM=TURRIS_OMNIA_MCU
75 Say Y here to add support for the true random number generator
76 provided by CZ.NIC's Turris Omnia MCU.
