From c750151e1107a8d46ca0f9bd30c1da276b142ec1 Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Thu, 26 Aug 2021 18:02:54 -0500 Subject: [PATCH 06/90] gpio: axp/sunxi: Remove virtual VBUS detection GPIO Now that this functionality is modeled using the device tree and regulator uclass, the named GPIO is not referenced anywhere. Remove it.
