Subject: [PATCH v3] arm64: tegra: jetson-tx1: Fix USB_VBUS_EN0 regulator
Date: Thu, 19 Nov 2020 15:23:45 +0800 [thread overview]
Message-ID: <20201119072345.447793-1-jckuo@nvidia.com> (raw)
USB Host mode is broken at OTG port of Jetson-TX1 platform because
USB_VBUS_EN0 regulator (regulator@11) is being overwritten by vdd-cam-1v2
regulator. This commit rearrange USB_VBUS_EN0 to be regulator@14.
Fixes: 257c8047be44 ("arm64: tegra: jetson-tx1: Add camera supplies")
