The scmdi2c driver provides the I2C frontend attachment
  for the Sparkfun SCMD device.
The following sysctl(3) variables
  are inherited from scmd(4) :
  - hw.scmd0.debug
- If the driver is compiled with SCMD_DEBUG, this
      node will appear and can be used to set the debugging level.
  - /dev/scmdu
- character device allowing access to the register space of a main
      u, SCMD device
Thescmdi2c driver first appeared in
  NetBSD 10.0.
