   4 Subject: mfd: lpc_ich: Enable GPIO driver for DH89xxCC
   5
   6 Based on the Intel Datasheet for the DH89xxCC PCH, the GPIO driver
   7 is the same as ICH_v5_GPIO, minus the fact the DH89xxCC also has
   8 blink support. However, blink support isn't supported by the GPIO
   9 driver so we should use ICH_v5_GPIO. Tested and working on a Meraki
  10 MX100-HW.
