Re: [Lcd-linux] [PATCH 1/2] MISC: driver for the character LCD found in ARM refdesigns

[Mattia Jona-L. <mat...@gm...>]

Hello Viktar, Linus & Ivan,

I'm certainly willing to submit lcd-linux in the Linux kernel
upstream. I was thinking about it, also because it is not
very efficient to introduce modifications just to keep it synced with
the normal kernel development.
Just give me some days to prepare an official announcement to the
kernel mailing list.

As far as I understood you work with embedded ARM based boards. This
could be a very good testbed for lcd-linux
since up to now I only tested it on i386 and sparc architectures, but
never on embedded systems.

What are the hardware requirements to make the display work on the ARM system?

Regards,

Mattia
