/*
 * This module implements suspend and resume commands for entering
 * and exiting ILI9225G sleep mode.  These commands are expected
 * to work the same on both HaoRan and Formike LCDs, but the
 * current measurement resistor that allows one to see the actual
 * power supply current drawn by the LCD is present only on lunalcd2
 * boards.
