This is a note to let you know that I've just added the patch titled arm64: dts: renesas: beacon kit: Fix choppy Bluetooth Audio to the 5.10-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: arm64-dts-renesas-beacon-kit-fix-choppy-bluetooth-au.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 5f02974d1a032f903b45ce305e797fa8ec61dd4e Author: Adam Ford <aford173@xxxxxxxxx> Date: Sun Dec 13 12:37:42 2020 -0600 arm64: dts: renesas: beacon kit: Fix choppy Bluetooth Audio [ Upstream commit db030c5a9658846a42fbed4d43a8b5f28a2d7ab7 ] The Bluetooth chip is capable of operating at 4Mbps, but the max-speed setting was on the UART node instead of the Bluetooth node, so the chip didn't operate at the correct speed resulting in choppy audio. Fix this by setting the max-speed in the proper node.
