Subject: [PATCH 2/2] ARM: dts: msm8974: castor: Add Bluetooth-related nodes
Date: Fri, 23 Jul 2021 20:21:01 +0000	[thread overview]
Message-ID: <20210723202101.65371-2-juw@posteo.de> (raw)
In-Reply-To: <20210723202101.65371-1-juw@posteo.de>

From: Bjorn Andersson <bjorn.andersson@linaro.org>

Castor has a BCM4339 attached to BLSP2 UART7, add the necessary nodes to
define the uart as well as the serdev BCM.
