Subject: [PATCH] ARM: dts: exynos: fix polarity of VBUS GPIO of Origen
Git-commit: a08137bd1e0a7ce951dce9ce4a83e39d379b6e1b
Patch-mainline: v6.1-rc1
References: git-fixes
EHCI Oxynos (drivers/usb/host/ehci-exynos.c) drives VBUS GPIO high when
trying to power up the bus, therefore the GPIO in DTS must be marked as
"active high". This will be important when EHCI driver is converted to
gpiod API that respects declared polarities.
