Not very detailed, but enough to "read between the lines" based on past experience. When you have a lot of experience with a lot of hardware, little hints can give away the whole secret.
Basically, I went from the device teardowns that identified the chips (epson) on K3, and backtracked to crossreference the part number and find a PDF with that part.
For the K4 and K5, I found eink literature from Freescale, which identified the eink controller integrated into the iMX508 SoC, and from there backtracked to a project for the illiad that has partial support for the same eink controller.
I found the "not known in this forum" secret ioctl for the k4/k5 (buried in very complex code) and extracted the essential ioctl parameters, then simplified it by "defaulting" a lot of stuff.
The freescale eink controller has a LOT of untapped potential here that we can explore (especially with a custom kernel)...
Basically, after multiple failed attempts in past months, I decided I really needed it now, and just kept looking (pretty much continuously for two days) until I found the secrets I needed to write code.
