Subject: [PATCH 2/2] ARM: dts: pandaboard es: add bluetooth uart for HCI
Date: Sat,  3 Oct 2020 16:10:01 +0200	[thread overview]
Message-ID: <eab9ebb735ab68f104623aa083b0e15f6ac263ea.1601734200.git.hns@goldelico.com> (raw)
In-Reply-To: <cover.1601734200.git.hns@goldelico.com>

The wl271 bluetooth uart is connected to uart2.
Setup a serdev uart child and separate bluetooth and uart2 pinmux
from wl12xx pinmux to better group the pins and muxes.
