Sync all am642-evm/am642-sk related DT files with Linux v6.5-rc1. - drop timer1 in favor of main_timer0 in am64-main.dtsi. Need to delete clock & power domain properties of main_timer1 in -r5.dts else won't boot. This is because timer_init is done during rproc_start to start System Firmware, but we can't do any clock/power-domain operations before System Firmware starts. - same constraint applies to main_uart0 - drop cpsw3g custom DT property 'mac_efuse' and custom DT node cpsw-phy-sel as driver picks these from standard property/node. - include board dts file in -r5 dts file to avoid duplication of nodes. Include -u-boot.dtsi on top. - drop duplicate nodes in -r5 dts and -u-boot.dtsi Signed-off-by: Roger Quadros <rogerq@kernel.org> Tested-by: Nishanth Menon <nm@ti.com> Reviewed-by: Nishanth Menon <nm@ti.com>
