This is a note to let you know that I've just added the patch titled arm64: dts: qcom: sc7280: Remove CTS/RTS configuration to the 6.10-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-qcom-sc7280-remove-cts-rts-configuration.patch and it can be found in the queue-6.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 958d715c7a19dea209397afcab094a851b0c2588 Author: Viken Dadhaniya <quic_vdadhani@xxxxxxxxxxx> Date: Wed Apr 24 13:28:53 2024 +0530 arm64: dts: qcom: sc7280: Remove CTS/RTS configuration [ Upstream commit 2b96407b8f10f1d71b58cb35704eb91b8ea78db1 ] For IDP variant, GPIO 20/21 is used by camera use case and camera driver is not able acquire these GPIOs as it is acquired by UART5 driver as RTS/CTS pin. UART5 is designed for debug UART for all the board variants of the sc7280 chipset and RTS/CTS configuration is not required for debug uart usecase. Remove CTS/RTS configuration for UART5 instance and change compatible string to debug UART. Remove overwriting compatible property from individual target specific file as it is not required.
