From 305398bfce771179f82940f428714651e6f3ad76 Mon Sep 17 00:00:00 2001 From: Aidan MacDonald Date: Wed, 10 May 2023 12:50:43 +0100 Subject: [PATCH] power: supply: axp20x_usb_power: Use regmap field for VBUS disabling The POWER_SUPPLY_PROP_ONLINE property allows controlling the VBUS enable state on supported PMICs. Switch to regmap fields to reduce dependence on variant IDs.
