 * We have no docs for the CHT Crystal Cove PMIC. The Asus Zenfone-2 kernel
 * code has 2 Crystal Cove regulator drivers, one calls the PMIC a "Crystal
 * Cove Plus" PMIC and talks about Cherry Trail, so presumably that one
 * could be used to get register info for the regulators if we need to
 * implement regulator support in the future.
 *
 * For now the sole purpose of this driver is to make

 * CHT Crystal Cove PMIC.
