This is a note to let you know that I've just added the patch titled arm64: dts: renesas: ulcb-kf: Remove flow control for SCIF1 to the 5.4-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-ulcb-kf-remove-flow-control-for-sc.patch and it can be found in the queue-5.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit dabb2fd0846a090677f98cc9ec06cf81fe0e6f29 Author: Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx> Date: Thu May 25 10:48:22 2023 +0200 arm64: dts: renesas: ulcb-kf: Remove flow control for SCIF1 [ Upstream commit 1a2c4e5635177939a088d22fa35c6a7032725663 ] The schematics are misleading, the flow control is for HSCIF1. We need SCIF1 for GNSS/GPS which does not use flow control.
