Subject: video: fbdev: atari: Fix TT High video mode
Git-commit: 54a84a3cf0a6070a410d8e3f02c2c6aa7f1bb22d
Patch-mainline: v5.18-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
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.
