From 280fa349757bb240c650882feee5a861150ccc2d Mon Sep 17 00:00:00 2001 From: Matthias Kaehlcke Date: Tue, 9 Apr 2019 16:14:05 -0700 Subject: ARM: dts: rockchip: Add BT_EN to the power sequence for veyron Add GPIO D5 (BT_ENABLE_L) as reset-GPIO to the power sequence for the Bluetooth/WiFi module. On devices with a Broadcom module the signal needs to be asserted to use Bluetooth. Note that BT_ENABLE_L is a misnomer in the schematics, the signal actually is active-high.
