Hello,
can you please queue up this to kernel v6.1-stable ?

    drm/bridge: ti-sn65dsi83: 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 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.

It solves a real issue with some displays not working without it.

Thanks,
Francesco
