[PATCH 4/4] rcar-du: add R8A7794 TCON support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Now that we have the TCON encoder driver, we can start enabling TCON support
for the  R-Car SoCs. We have only tested the code on R8A7794 so far, so  let
it  be the first supported SoC...

Based on a large patch by Andrey Gusakov.
