Hi Marek,
Hi,
Thank you for testing and keeping up with this. I will wait for more
feedback if there is any (Frieder? Lucas? Michael?). If there are no
objections, then I can merge it in a week or two ?
I'll try to use your approach on the tc358775. Hopefully, I'll find
some time this week.
So ... I wonder ... shall I apply these patches or not ?
As mentioned on IRC, I tried it to port it for the mediatek DSI
host, but I gave up and got doubts that this is the way to go. I
think this is too invasive (in a sense that it changes behavior)
I would argue it makes the behavior well defined. If that breaks some
drivers that depended on the undefined behavior before, those should be
fixed too.
and not that easy to implement on other drivers.
How so ? At least the DSIM and STM32 DW DSI host can switch lanes to
LP11 state. Is the mediatek host not capable of that ?
Given that this requirement is far more common across DSI bridges,
I'd favor a more general solution which isn't a workaround.
I think we only had a look at the TI DSI83 / ICN6211 / Toshiba TC358767
bridges, but we did not look at many panels, did we ? Do panels require
lanes in non-LP11 state on start up ?
Was there any progress on the generic LP11 solution, I think you did
mention something was in progress ? How would that even look like ?
