From d0c5ac04e7feedbc069f26f4dcbf35b521ae7fc5 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 4 Mar 2021 01:41:38 +0100 Subject: [PATCH 01/76] drm/mcde/panel: Inverse misunderstood flag A recent patch renaming MIPI_DSI_MODE_EOT_PACKET to MIPI_DSI_MODE_NO_EOT_PACKET brought to light the misunderstanding in the current MCDE driver and all its associated panel drivers that MIPI_DSI_MODE_EOT_PACKET would mean "use EOT packet" when in fact it means the reverse. Fix it up by implementing the flag right in the MCDE DSI driver and remove the flag from panels that actually want the EOT packet.
