> it's an i.MX6SL, I thought we mentioned that on the web page.

Your website only says: "Processor 1 GHz ARM A9 CPU"

> Two from freescale for the imx6 and imx7

Ok, but you are using imx6.

> There's also another one written by lab126

Nope. That's the same driver from Freescale. You can download the kindle source to verify. https://www.amazon.com/gp/help/customer/display.html?nodeId=...

> then you have the u-boot drivers.

u-boot just draws a splash screen.

> you have the 5bit waveform support, which is a whole other story (with iffy GPL implications for some vendors I won't name).

I don't understand what you're trying to communicate. Why would a EPD waveform have any GPL implications? An EPD waveform is not software, it is a set of timing values and that's it.

> the display was designed based on our requirements

I'm having difficulty understanding what that means. It sounded like you were saying E Ink designed a panel for you, but maybe what you're saying is just that E Ink had a panel that met your requirements.

there are two epdc drivers in the kindle gpl releases. the source for the lab126 one is only available in the tarballs you linked (named mxc_epdc_fb_lab126.c).

as for the waveforms, I'm talking about support for the REAGL (sic) waveforms. grep for it in the linux source in the tarballs you linked to.

and e ink did not have a panel that met our requirements, and designed a new one after we talked with them.

edit; just to be clear, we don't use the lab126 driver, it was just an example of there being more drivers for the imx6 generation epdc.
