[-- Attachment #1: Type: text/plain, Size: 147212 bytes --]
From: Krzysztof Helt <krzysztof.h1@wp.pl>
This is a basic port from 2.4 kernel to 2.6. Acceleration is lost
and big endian support probably too. The driver works in 8, 16
and 32 bit mode.
Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl>

This is a first trial of porting this driver. The driver work may
contain many bugs.

There was a 1.4.11C, which I believe was included in 2.4.26-pre2 .
And if my IRISA e-mail address is still in the source, it's probably

I noticed it after I started this port. Anyway, this driver is
very basic comparing to the 2.4 version. I'll try update the
driver if time will allow, I learned I cannot promise finishing
drivers because real life always steps up in the most unexpected
moment.
I welcome any help to fix big endian (PPC) support for this
driver as I do not have hardware to do this.

I hope, that Antonio can do this in order to avoid resend of this
big patch.
Best regards,
Krzysztof

Thanks for doing this. I change the VESA_* constants to FB_BLANK_*
constants. It's just a simple substitution, but let me know if it's
correct. (I don't know what to do with FB_BLANK_UNBLANK.)

Thank you. I assume that FB_BLANK_NORMAL means screen off.
Add this case for FB_BLANK_UNBLANK:
case FB_BLANK_UNBLANK:
video = video | PM3VideoControl_ENABLE;
break;

Krzysztof
