The following commit syncs the device tree from Linux tag next-20230815 to U-boot and fixes the following to be compatible with the future syncs - - Include k3-am68-sk-base-board.dts file Remove the duplicated pinmuxes from r5 and -u-boot.dtsi files and include k3-am68-sk-common-proc-board.dts for Linux fixes to propagate to U-boot. - Fixing the mcu_timer0 Remove timer0 and use the mcu_timer0 defined in mcu-wakeup.dtsi The device manager is not functional at this point so we can't configure the clocks for the mcu_timer0, delete the properties that enable the clocks and power domains for it. - Fixing secure proxy nodes Linux DT now have these nodes defined so remove them and rename to use the Linux DT ones. - Remove cpsw node The compatible is now fixed and the node is not required in -u-boot specifically - Remove aliases and chosen node Use these from Linux and don't override when not required. - Remove dummy_clock_19_2mhz This wasn't being used anywhere so remove it. All these have been put in a single commit to not break the bisectability.
