From dad204699d870a86849a635ebec84f3259923a0e Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Thu, 4 Feb 2021 14:23:58 +0000 Subject: [PATCH] dt: Add option for dpi without DE and PCLK (for VGA666) VGA666 doesn't use the DE or PCLK signals, therefore there is no point in claiming their use. It's also then possible to use GPIOs 0&1 for DDC to read the EDID from the display.
