From b18f1ecaaf4aa8704a02de1accf8c94fa06f1ceb Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Tue, 4 Apr 2023 00:12:32 +0200 Subject: drm/bridge: lt9211: Do not generate HFP/HBP/HSA and EOT packet Do not generate the HS front and back porch gaps, the HSA gap and EOT packet, as these packets are not required. This makes the bridge work with Samsung DSIM on i.MX8MM and i.MX8MP.
