Subject: [PATCH 2/2] arm64: dts: rockchip: Fix compatible for Bluetooth
Date: Mon,  8 May 2023 11:08:11 -0500	[thread overview]
Message-ID: <20230508160811.3568213-3-macroalpha82@gmail.com> (raw)
In-Reply-To: <20230508160811.3568213-1-macroalpha82@gmail.com>

From: Chris Morgan <macromorgan@hotmail.com>

The realtek Bluetooth module uses the same driver as the
realtek,rtl8822cs-bt and the realtek,rtl8723bs-bt, however by selecting
the 8723bs advanced power saving features are disabled that appear
to interfere with normal operation of the bluetooth module. This
change switches the compatible string to disable power saving. Without
this patch evtest of a paired bluetooth controller fails, with this
patch the controller operates as expected.

Fixes: b6986b7920bb ("arm64: dts: rockchip: Update compatible for bluetooth")
