From a33c6a22f6d616caab6f5a5bfaa7ee01ea567d82 Mon Sep 17 00:00:00 2001 From: Martin Botka Date: Sat, 1 Apr 2023 01:18:48 +0100 Subject: [PATCH] dt-bindings: mfd: x-powers,axp152: Document the AXP313a variant 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.
