    You are over simplifying things.

    1) The code is open[1]
    2) the decision comes from TI, Nokia can only do so much before shipping
    3) I know many people in Nokia have pushed very hard, and cleaned up
    the driver a lot themselves
    4) There are other companies, Intel is using SGX too

    Anyway, there are other examples, like tidspbridge, which Nokia has
    spent a lot of time cleaning up, and TI made a great effort to push
    into staging. And others already in mainline, like
    sh_mobile_ceu_camera.
