[1] https://git.kernel.org/pub/scm/linux/kernel/git/devicetree/devicetree-rebasing.git - Remove netc_timerX nodes from arch/arm/dts/imx943-u-boot.dtsi as they are now upstream - Move dts/upstream/include/dt-bindings/reset/bcm6318-reset.h to include/dt-bindings/reset/bcm6318-reset.h as upstream has removed this file as unused (but we use it).
