[PATCH 5.10 09/25] ARM: dts: exynos: Fix BCM4330 Bluetooth reset polarity in I9100

From: Greg Kroah-Hartman
Date: Fri Jan 14 2022 - 03:19:28 EST


From: Paul Cercueil <paul@xxxxxxxxxxxxxxx>

commit 9cb6de45a006a9799ec399bce60d64b6d4fcc4af upstream.

The reset GPIO was marked active-high, which is against what's specified
in the documentation. Mark the reset GPIO as active-low. With this
change, Bluetooth can now be used on the i9100.
