11 Say Y here to be able to choose driver support for CZ.NIC's Turris
12 devices. This option alone does not add any kernel code.

19 depends on I2C
20 help
21 Say Y here to add support for the features implemented by the
22 microcontroller on the CZ.NIC's Turris Omnia SOHO router.
23 This option only enables the core part of the driver. Specific
24 features can be enabled by subsequent config options.
25 To compile this driver as a module, choose M here; the module will be
26 called turris-omnia-mcu.

37 Say Y here to add support for controlling MCU GPIO pins and receiving
38 MCU interrupts on CZ.NIC's Turris Omnia.
39 This enables you to
40 - get front button press events (the front button can be configured
41 either to generate press events to the CPU or to change front LEDs
42 panel brightness),
43 - enable / disable USB port voltage regulators and to detect USB
44 overcurrent,
45 - detect MiniPCIe / mSATA card presence in MiniPCIe port 0,
46 - configure resets of various peripherals on board revisions 32+,
47 - enable / disable the VHV voltage regulator to the SOC in order to be
48 able to program SOC's OTP on board revisions 32+,
49 - get input from the LED output pins of the WAN ethernet PHY, LAN
50 switch and MiniPCIe ports.
