Low-level access to Kobo eink panel
I've started hacking on the screen level on the Kobo platform.
It seems all the code we need to drive the panel is in the kernel source, under linux-126.96.36.199/drivers/video/mxc; in particular the relevant files are attached to this post.
"epdfb_dc.c" is already compilable as a stand-alone program, provided you add a "main" function to it.
I'm trying to do something useful with those functions but I haven't figured out yet how to use them. I'm sharing the info in case someone else wants to work on this.
