Thanks for your note. To comply to the GPL v2 liscense, we will open source the code in the future. We choose to release the biinaries but not the source code, it's because the code is not yet merged into the raspi mainline, so compiling the driver for each kernel version may be the best choice.

For GMSL serializer, deserializer, and image sensor, each part of them should have an individual driver, just like the NVIDA GMSL driver framework. But for most developpers, it still need to do a lot of work to adapt the driver, which requires strong professional skills. While there's a simpler method, which is to group all of the modules together and treat them as a single image sensor. In this way, most cameras can be adapted by modifying the configuration table.

The configuration table only needs to be done at the application layer, so that the driver compatibility will be much higher. This is the most suitable solution we can think of at this moment, and we have implemented this method on other platforms and will implement it on the raspi platform.

MAX9286 ​​and MAX9271 are ADI(MAXIM) GMSL-1 generation products, which are quite different from the current GMSL-2 (MAX9296/MAX96712), and they can not be compatible. Our suggestion is to treat a deserdes as a driver unit and hide the serdes and sensor in the configuration table for easier adaption.
