From dd5297cc8b8b8422b0876b2e7fea8cc2eec4aa2d Mon Sep 17 00:00:00 2001 From: Christian Hewitt Date: Sat, 13 Oct 2018 16:07:06 +0400 Subject: [PATCH] arm64: dts: meson-gxl-s905x-khadas-vim enable Bluetooth This enables Bluetooth support for the following models: - Khadas VIM basic (AP6212) using firmware BCM43438A1.hcd - Khadas VIM pro (AP6255) using firmware BCM4345C0.hcd The AP6212 module used on the VIM basic has an ID clash with another device. To get Bluetooth working you either need to apply a kernel patch to drivers/bluetooth/btbcm.c so 0x2209 loads BCM43438A1 or the BCM43438A1.hcd firmware must be renamed to BCM43430A1.hcd.
