From: Andre Przywara <andre.przywara@arm.com> The X-Powers AXP318W is a PMIC used on some newer Allwinner devices. Among a large number of both DCDC and LDO regulators it features the usual ADC/IRQ/power key parts. Like other recent PMICs, it lacks the DC/DC converter PWM frequency control register, that rate is fixed here (1.5MHz on DCDC1, 3 MHz on the others). Add the new compatible string, and add that to the list of PMICs without the PWM frequency property. Also add more input supply properties, for the split DCDC and ALDO supplies. The PMIC features *two* switched outputs, hanging of DCDC1, and the manual calls them swout1 and swout2, so follow suit here and add those names to the pattern for matching the node names.
