[PATCH 0/7] arm64: dts: renesas: r8a779md: Add support for R-Car M3Le R8A779MD SoC and Geist board

[Marek Vasut]

Add support for the Renesas R-Car M3Le (R8A779MD) SoC, a register-compatible
variant of the R8A77965 (M3-N) with reduced set of peripherals. Add support
for the Geist board based on the Renesas R-Car R8A779MD (M3Le).

The DU part does probe, and to the best of my knowledge, should correctly
describe the hardware, but is otherwise untested due to no remote display
access. Note that the DU uses ports 0 and 2, which is unusual.

VIN is also untested due to no remote hardware access.

[PATCH 1/7] dt-bindings: display: renesas,du: Document Renesas R-Car R8A779MD M3Le

[Marek Vasut]

Extend the Renesas DU display bindings to support the Renesas R-Car
R8A779MD M3Le SoC. This SoC is similar to R-Car R8A77965 M3-N SoC,
except the HDMI port@1 is not present.

[PATCH 7/7] arm64: dts: renesas: r8a779md: Add support for R-Car M3Le R8A779MD Geist

[Marek Vasut]

From: Nguyen Tran <nguyen.tran.pz@bp.renesas.com>

Add support for the Geist board based on the Renesas R-Car R8A779MD (M3Le)
SoC, a register-compatible variant of the R8A77965 (M3-N) with reduced set
of peripherals. The Geist board design references the Renesas Salvator-X/XS
boards, adapting their configuration for the R8A779MD SoC.

I am not sure you need a new compatible value: is the DU really
different than on R-Car M3-N, or does it just lack some wiring? ...

Perhaps port@1 can be present (and thus required), but left unconnected

Your arch/arm64/boot/dts/renesas/r8a779md.dtsi only has two entries
in renesas,cmms and renesas,vsps?

 "BIT(3) | BIT(0)", given R-Car M3Le dropped DU1, not DU3?

I also don't know where "M3Le does not support 4K output." (which is
a VSP2 limitation) is to be handled.

While CP2000 exists in two variants (-CP and -OTP, cfr. the link below),
there is just "CP2500"[2].

I am not sure disabling sdhi3 is correct.
The R-Car M3Le documentation says:

   "M3Le does not support MMC1.
    M3Le supports one MMC channel (MMC0) only.
    SD3 is used only for SDHI and is not used for MMC.
    M3Le does not support MMC HS400 class transfer rate."

The main R-Car Gen3 documentation says:

   "This LSI has four SD card interfaces (SDHI0 to SDHI3), two of
    which can also be used as MMC interfaces (SDHI2 and SDHI3)."

So while MMC1 is indeed sdhi3, sdhi3 can still be used in SD mode?
Do we need a new compatible value, as R-Car M3Le does not support HS400?

Shouldn't the following be disabled, too?
  - ohci1, ehci1, and usb2_phy1,
  - cmm1 and vspd1 (cfr. DU below).

Assuming the DU needs a new compatible value...

> +       renesas,cmms = <&cmm0>, <&cmm3>;
> +       renesas,vsps = <&vspd0 0>, <&vspd1 0>;

Shouldn't this be

    renesas,vsps = <&vspd0 0>, <&vspd0 1>;

? DU1 is unused, but DU3 is used.
