From 50252c318fe2fcfcbd0832fa835e7fd1fafd7d2d Mon Sep 17 00:00:00 2001 From: Peter Robinson Date: Sun, 10 Sep 2017 19:30:02 +0100 Subject: [PATCH 2/2] ARM: dts: bcm2837-rpi-3-b: Add bcm43438 serial slave Add BCM43438 (bluetooth) as a slave device of uart0 (pl011/ttyAMA0). This allows to automatically insert the bcm43438 to the bluetooth subsystem instead of relying on userspace helpers (hciattach). Overwrite chosen/stdout-path to use 8250 aux uart as console.
