The MCU CPSW Common Platform Time Sync (CPTS) provides possibility to
timestamp TX PTP packets and all RX packets.
This enables corresponding support in TI AM65x/J721E MCU CPSW driver.

Should this be TI_K3_AM65_CPTS ?
instead of 'imply TI_K3_AM65_CPTS' don't you want to do this:
'depends on TI_K3_AM65_CPTS || !TI_K3_AM65_CPTS'
Right, I'll try. It seems your defconfig is produced by randconfig as
I can't get broken cfg TI_AM65_CPTS=m and TI_K3_AM65_CPSW_NUSS=y
with neither one below:
make ARCH=arm64 O=k3-arm64 defconfig
make ARCH=arm64 O=k3-arm64 allnoconfig
make ARCH=arm64 O=k3-arm64 allyesconfig
