Yep, I know that in general a DSA switch can be configured via the
platform data as any other device. But in this particular case, the
particular 88E6060 switch support can not be switched to the DSA
implementation because the DSA implementation does not support
configuration via the platform data.

I checked the kernel code and the OpenWrt patches and found the only
board with the 88E6060 switch and this board utilizes DTS for its
configuration:

openwrt $ grep -rn 'mv88e6060'
build_dir/target-mips_mips32_musl/linux-ath25/linux-5.10.87/arch/
openwrt $ grep -rn 'mv88e6060' target/linux/
target/linux/ath79/dts/ar9132_tplink_tl-wr941-v2.dts:68: compatible =
"marvell,mv88e6060";

So, I can not find which example you mean. But I may not have
understood your input. Please explain where I made a mistake?
