-	    rtcwake)
-	  - true random number generator (if available on the MCU)

-	  - GPIO pins
-	    - to get front button press events (the front button can be

-	      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
+	  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
