Subject: [PATCH v9 1/3] dt-bindings: mfd: x-powers,axp152: Document the AXP313a variant

From: Martin Botka <martin.botka@...ainline.org>

The X-Powers AXP313a is a PMIC used on some devices with the Allwinner
H616 or H313 SoC.
According to the datasheet, the DC/DC converter PWM frequency is fixed
(to 3 MHz), so disallow the property that lets us set this frequency
for the other PMICs.
