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
depends on OF
depends on GPIOLIB
depends on HW_RANDOM
depends on RTC_CLASS
select GPIOLIB_IRQCHIP
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)
- 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
Other 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.
if TURRIS_OMNIA_MCU
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.
