For university research purposes, I am searching for a specific part of Nexus 6, and Samsung Galaxy S6 source code. Particularly, I am interested in "network" & "storage" driver source codes. I have visited developer resources for both Samsung (which are said to be open-sourced), and Motorolla, but was unable to find the desired code.
I also have the pure Android source code on this website, but I guess the drivers for "network" & "storage" might be hardware-specific.
I am having a hard time locating "network" & "storage" drivers for the mentioned two devices. In case the code I am looking for is open-sourced, can anybody please let me know where they are located?
