[PATCH v2 3/3] arm64: dts: renesas: Add LVDS decoder to R-Car V3M Eagle

Fri Mar 9 13:51:40 UTC 2018


The R-Car V3M Eagle board includes a transparent LVDS decoder, connected
to the on-chip LVDS encoder output on one side and to HDMI encoder
ADV7511w on the other one.

As the decoder does not need any configuration it has been so-far
omitted from DTS. Now that a driver for transparent LVDS decoder is
available, describe it in DT as well.
