ARM: dts: exynos: Fix BCM4330 Bluetooth reset polarity in I9100 2022-01-16T08:11:13+00:00 Paul Cercueil paul@crapouillou.net 2021-10-31T23:41:36+00:00 1b24117dcfa858b89616b0d41f290c60facef755 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.
