Subject: [PATCH/RFC] video: fbdev: atari: Fix TT High video mode
Date: Sun,  1 Nov 2020 11:27:59 +0100	[thread overview]
Message-ID: <20201101102759.2890612-1-geert@linux-m68k.org> (raw)

The horizontal resolution (640) for the TT High video mode (1280x960) is
definitely bogus.  While fixing that, correct the timings to match the
TTM195 service manual.

Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
---
Untested on actual hardware, hence the RFC.
