Subject: [PATCH v2 1/2] ARM: dts: exynos/i9100: Fix BCM4330 Bluetooth reset
|
||
|
|
polarity
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
Fixes: 8620cc2f99b7 ("ARM: dts: exynos: Add devicetree file for the Galaxy S2")
