Hello everyone,

Hi,

Thank you a lot for your prompt feedbacks.
I'm really sorry for all the mistakes, it is the first time that I try to
submit a patch and i thought I followed the guideline but clearly that was
not the case.

@Marek Vasut <marex@xxxxxxx> About your question to why disabling
burst-mode:
- I agree with you that Burst Mode is the preferred way to send data. For
that reason I created the new flag in a way that, if not used in dts, burst
mode remains active by default.
However, I decide to introduced this property because I have noticed that
some dual-channel panels work better in non-burst mode (even if less
efficient), and since the sn65dsi84 datasheet allows this setting, I
thought to give this opportunity to users.
What do you think about it?

Are there any further details, which panels behave this way ? Does your DSI host generate correct HS clock, ones which the DSI84 expects to receive on the DSI side ?

Such link mode properties would have to be generic properties placed in some dsi-client.yaml file in any case, such properties are not specific to this DSI8x bridge.
