SubjectRe: [PATCH v5 3/3] arm64: dts: renesas: Add LVDS decoder to R-Car V3M Eagle
Hi Jacopo,

Thanks for your patch.

This one must depend on '[PATCH v2 0/5] arm64: dts: renesas: r8a77970:
enable HDMI output' or something similar not yet in renesas-drivers
repository correct?

In the next version would you care to include the LVDS commit from the
dependency series and squash this change into that one or in some other
good manger stack to two? Laurent told me he did not like 5/5 in that
patch-set as it did not yet have the LVDS decoder node due to no driver
existed at that time when I posted that even if it's not strictly needed
to get the display working :-)

I also think you should split this last patch out to a separate series
as it should go in Simon's tree while the driver and documentation is
going in earlier in a different tree right?

On a side note, do you plan to update the Gen2 boards DTS files which
also have a decoder which are not yet described in DT?
