If anyone has any objections, please let me know. ------------------ From: Marek Vasut <marex@xxxxxxx> [ 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.
