From 39101f1314ba38fca8b2ab8ed42622529d18342e Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Mon, 11 Jul 2022 17:50:32 +0200 Subject: [PATCH] video: fbdev: atari: Fix VGA modes The pixclock values in the vga and vga70 modes are wrong, as they should use the 25.175 MHz clock instead of the 32 MHz clock. Swap the left and right margins to match f25.{right,left} (struct pixel_clock declares them in a different order), and update the hsync lengths to match what the driver programs by default. Correct the (wrong) floating-point vrefresh value for the vga mode.
