[PATCH v2 0/5] enable DMA and CPSW nodes for am62ax SoC family

Hello again everyone!
This patch series syncs TI's am62ax device tree files with what has been merged in the v6.3-rc4 of the Linux Kernel. This series will also enable YMODEM support to make automated testing (which uses the UART boot method to load the bootloaders)
Thanks for reviewing ~Bryan
Changed from v1: [0]
o Rebased on top of -next branch o dropped 'u-boot,dm-spl' for the new 'bootph-pre-ram' properties

Hello again everyone!
This patch series syncs TI's am62ax device tree files with what has been merged in the v6.3-rc4 of the Linux Kernel. This series will also enable YMODEM support to make automated testing (which uses the UART boot method to load the bootloaders)
Thanks for reviewing ~Bryan
