I've just unearthed this topic in my mailbox and tried a port myself based on your V2 patch.

You will find the updated version in a branch of my staging repo here:
https://git.openwrt.org/?p=openwrt/staging/adrian.git;a=shortlog;h=refs/heads/mr6400

(Most recent patch there.)

Despite several minor issues (sorting, rebase, etc.) I've also addressed the following major issues:
1. Use gpio-export again instead of gpio-hog, so LTE can be switched on/off
2. Added adb-enablemodem
3. Removed the phy-swap in DTS. This is not present in the mach-file for mr6400, only in the one for the fritzbox 4020 you took as blueprint.
4. Adjusted ports 2 vs. 3 in 02_network based on your assessment. This will most probably be wrong again now, as this might be influenced by the phy-swap.
5. LAN/WAN LEDs still won't work properly, as at least one will need to be changed to ucidef_set_led_switch, and I cannot check that without the device.

Best

Adrian
