[PATCH/RFC v2] arm64: r8a77965 Salvator-X SoC/board support prototype

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

 



From: Magnus Damm <damm+renesas@xxxxxxxxxxxxx>

Here's V2 of a simple prototype hack to get the R-Car M3-N SoC working with
the r8a77965 Salvator-X. This version has been updated to fit on top of
"renesas-drivers-2018-01-09-v4.15-rc7".

The following patches are picked from renesas-bsp @ kernel.org and
in particular the recent "rcar-3.5.9.rc2" release:

dca5c4d1adc6 arm64: renesas: Add Renesas R8A77965 Kconfig support
6f3c0086b8b2 soc: renesas: identify R-Car M3N
711dec8fc1df soc: renesas: rcar-rst: Add R8A77965 support (*)
c8418d81dd26 clk: renesas: Add r8a77965 CPG Core Clock Definitions
d642ad7d1a40 clk: renesas: cpg-mssr: Add support for R-Car M3N (*)
4cec6dcde2f5 arm64: dts: r8a77965: Add Renesas R8A77965 SoC support (*)
92be4952a4d5 arm64: dts: r8a77965-salvator-x: Add Salvator-X board on R8A77965 SoC support (*)
1c69363cc1eb arm64: dts: r8a77965-salvator-x: Add reserved memory regions

Commits above original author is Kihara-san:
Signed-off-by: Takeshi Kihara <takeshi.kihara.df@xxxxxxxxxxx>

Commits marked with (*) above have been updated to fit on upstream

Since this is prototype code and not suitable for mainline merge as-is:
