[PATCH v3 1/4] dt-bindings: mfd: x-powers,axp152: Document AXP318W

From: Jerome Brunet

Date: Fri Jul 17 2026 - 04:45:55 EST


From: Andre Przywara <andre.przywara@xxxxxxx>

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.
