From 15d4325fd6c79ec8e44f99053d2d0d2538b17a8a Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Mon, 15 Mar 2021 06:37:14 +0000 Subject: [PATCH] arm64: dts: renesas: beacon kit: Fix choppy Bluetooth Audio stable inclusion from stable-5.10.20 commit 072552f973ad1143e296f858a820d64c20b53821 bugzilla: 50608 -------------------------------- [ 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.
