[PATCH 2/8] [RFC] arm64: dts: renesas: Add R-Car H3 SiP (4 x 1 GiB) support

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

 




Add support for the R-Car H3 System-in-Package (r8j7795), which contains:
  - an R-Car H3 SoC (r8a7795),
  - 4 channels of 1 GiB of RAM (4 GiB total),
  - HyperFlash (not yet described).

Signed-off-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>

Questions:
  - Should this file be named r8j7795-4g.dtsi instead?
  - Do other versions (different memory configuration) of r8j7795 exist?
    If yes, how are they named?
