From ccc91b3ed3f641efa8e9050c587ef509b0e2be3a Mon Sep 17 00:00:00 2001 From: Andreas Kemnade Date: Thu, 8 Dec 2022 22:57:23 +0100 Subject: [PATCH] mfd: twl: Fix TWL6032 phy vbus detection TWL6032 has a few charging registers prepended before the charging registers the TWL6030 has. To be able to use common register defines declare the additional registers as additional module. At the moment this affects the access to CHARGERUSB_CTRL1 in phy-twl6030-usb. Without this patch, it is accessing the wrong register on TWL6032. The consequence is that presence of Vbus is not reported.
