Yes, there is a probability, so we also need to modify the dsi.c

it looks like disabling EOTP, not enabling.

What does EOTP do?

EoTp is End of Transmission packet (EoTp) defined in dsi spec.

What changed? How do you verify EOTP works? As new print statements are added, maybe also paste that […]

We test it with dsi protocol tool. The protocol tool can receiver the EoTp packet.

Yes, you are right.

The comment lets me misunderstood the "MIPI_DSI_MODE_EOT_PACKET". /* disable EoT packets in HS mode */ MIPI_DSI_MODE_EOT_PACKET = BIT(9),

I'll correct the wrong setting in soc dsi.

Looks more like debug information. Otherwise, please rephrase to be better understandable.

Yes, this is debug info.

I'll remove next patchset.

soc/mediatek: dsi: Fix EoTp flag

SoC will transmit the EoTp (End of Transmission packet) when MIPI_DSI_MODE_EOT_PACKET flag is set.

Enabling EoTp will make the line time larger, so the hfp and hbp should be reduced to keep line time.
