@lukasz92, can you post your sources on git (or anywere) please. It will really help in developing openwrt for r3p.

@lukasz92 can you offer any help or advice for the Xiaomi R3P over here please. Ilyas is working his/her butt off trying to iron it all out.
@souk it's "his" (not "her") 
i'm really not so much after advice as source code (and an explanation of what @lukasz92 did... he mentions "opensource mt7615 driver" but there are no opensource mt7615 drivers... he talks about "only needing patched mt76-core package" but the mt76 module is completely unrelated to the closed-source mt7615 modules)... so i'm not sure what this "patch" he's talking about is...
btw, @lukasz92 ... congratulations on managing to compile that... it's a real pile. i'm working on doing the same now... (and yes, you should still post your code/patches)
Not really at this moment, driver is not ready. The current target is to push support (without WiFi) for R3P device to OpenWRT, and then introduce wifi support.
@ilyas https://pastebin.com/raw/N7zLMagn this is the patch for OpenWRT 18.06.2 that will allow to build kernel module; I generated it from publicly available source on github.
As I have written, this is an early development version and will probably not work.
As development speed is promising, I hope we will see this driver in the second next release of OpenWRT.

@lukasz92 i stand corrected, humbled, and embarassed... i had no idea the mt76/mt7615 development was so far ahead... now your message makes complete sense. i had been assuming you had "patched" the closed-source (SDK) module source (which I was trying to locate)... my apologies. and thanks for the answer and the code.
Has anybody already tried it on OpenWrt? Very curious but don't have any MT7615 hardware myself.
Has anyone got the MT7615 driver running successfully?
I'm trying to add support for the Linksys EA7500-AH v2 router. The image I built off master is able to boot successful for the EA7500. The mt7615e driver is able to load and I can see both wireless interfaces in Luci, but it doesn't seem to work.
For one, I only see WEP encryption and when I enabled the interface, my wireless clients could not see the SSID.
The EA7500-AH v2 seems to be based on the EA7400 v2 with the following specs:
MT7621A SoC
MT7615N wireless chip
128 MB NAND flash
256 MB RAM
From the components used, it looks like the TP-Link RE650 matches the EA7500-AH v2. Has anyone got wireless radio working with the TP-Link RE650 repeater?
Drivers work fine on my custom build for the R6700 v2. Only thing not working are some leds, as they cannot be simply controlled by gpio.

Great! Are you building your own firmware image? Do you mind sharing the DTS file and what else you did to make it work?

@Chief, it turns out that the OpenWRT master branch driver is working after all. My issue was that when I added support for the EA7500-AH v2 router, my build somehow did not include the wpad-basic package. Adding that package makes the wireless interface works.
Do you have problem with range tho? My wireless devices fails to connect to the router when they move away from the router, e.g. when the signal passes thru walls. Can only connect reliably to the router when the wireless clients are near the router.
Try these, if not using them already: https://github.com/MeIsReallyBa/mt76/commit/133bffba8bb2cafb1583c2306a670625d187144c
Compared the 3 files with the ones I'm using, which is from the OpenWRT master branch. They are identical.

look's like you board has lost it's factory calibration data
or is not correctly configured to read it's calibration data
more info is needed openwrt version router model number etc
