+Subject: drm/bridge: ti-sn65dsi83: Do not generate HFP/HBP/HSA and EOT packet
+
+From: Marek Vasut <marex@denx.de>
+
+[ Upstream commit f4d324fb5628773907dd90342d18f978bd9a6d09 ]
+
+[ Upstream commit ca161b259cc84fe1f4a2ce4c73c3832cf6f713f1 ]
+
+Do not generate the HS front and back porch gaps, the HSA gap and
+EOT packet, as per "SN65DSI83 datasheet SLLSEC1I - SEPTEMBER 2012
+- REVISED OCTOBER 2020", page 22, these packets are not required.
+This makes the TI SN65DSI83 bridge work with Samsung DSIM on i.MX8MN.
