There are tons of mobile drivers out there. When VR and AR just started to pick up, hackers used to make relatively inexpensive FPGA-based solutions, but nowadays you can get an aftermarket board with proper mipi or eDP driver for under $30. I've even seen dual-display drivers on Ali specifically for VR. There are also many kits similar to whatever was used in Rift DK2 (just a smartphone screen w/ driver).
Using this thing isn't a problem. Getting it cheap - is. At $150 it's actually on the edge of being cost-effective to just get a pair of blocks and tear them down for DIY HMD project. You'll probably end up with something similar to OSVR at nearly identical BOM tally, but it's DIY - fun and education is priceless.
Eh? You have the display IC driver source and it can be compiled with any ARM/MIPS whatever platform out there? I guess not. You rely on the already made most probably MIPI interface, which pretty closed legal wise.
They are bought as a whole and Chinese use them as lego. Nobody will write and addon that requires something so specific like that, China is very weak on software, they make pretty interesting HW products, but the software side is always lacking or stolen.
It went offtopic, but product as such as such small quantities is like drop in bucket, to your ambitious claim seeing in various smart home devices, that would require basically whole software stack rewrite and basic hardware upgrade, that also ain't feasible in times like these. Those smart devices will not ever use some additional converters or boards, just price wise, they have to talk to screen directly without any additional BOM, to remain competitive, not just vaporware, basically like this waterblock is.
You can have fun at home an source parts from Ali. But not on commercial scale.
