From 072552f973ad1143e296f858a820d64c20b53821 Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Sun, 13 Dec 2020 12:37:42 -0600 Subject: [PATCH] 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.
