From 224771c947640613a822e7c8fa0d6d7d87fbd266 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Wed, 22 Apr 2020 12:46:07 +0200 Subject: [PATCH] ARM: dts: stm32: Enable Bluetooth on AV96 The WiFi/Bluetooth chip is attached to USART2 on AV96 as well, describe it in DT to make it available. Remove BT LED and turn it into a shutdown GPIO, because the GPIO line controls the BT_REG_ON signal. The LED is just an indicator connected to the same line, but not the primary function.
