[PATCH 6.12.y-cip 00/11] Add initial support for RZ/V2N EVK

[Ovidiu Panait]

Hi,

This series adds initial support for the Renesas RZ/V2N EVK platform. It
provides the basic SoC and board dts files and enables the following core
functionality:
  - CPU (Cortex-A55 cores with operating points)
  - External clocks (audio, qextal, rtxin)
  - Pin controller (GPIO support)
  - Clock Pulse Generator (CPG)
  - System controller (SYS)
  - Serial Communication Interface (SCIF)
  - Secure Digital Host Interface and eMMC (SDHI)
  - Generic Interrupt Controller (GIC)
  - ARMv8 timer

Note that the RZ/V2N SoC shares most functionality with the RZ/V2H SoC,
which is already supported in the CIP kernels, so most of the required
driver infrastructure is already available.

Thanks,
Ovidiu

[PATCH 6.12.y-cip 01/11] dt-bindings: soc: renesas: Document Renesas RZ/V2N SoC variants and EVK

[Ovidiu Panait]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

commit abc43c0f3c3eaa7470004e4e8a190a57c612a686 upstream.

Document the Renesas RZ/V2N (R9A09G056) SoC variants, distinguishing
between configurations with and without specific hardware features such
as GPU, ISP, and cryptographic extensions. Also, document the
"renesas,rzv2n-evk" compatible string for the RZ/V2N EVK board.

[PATCH 6.12.y-cip 02/11] soc: renesas: Add config option for RZ/V2N (R9A09G056) SoC

[Ovidiu Panait]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

commit 31d358e611b7cc21349da58dd2c9118c84b0859f upstream.

Add a new Kconfig option, ARCH_R9A09G056, to enable ARM64 platform support
for the Renesas RZ/V2N SoC. Default this option to "y" when ARCH_RENESAS is
enabled, ensuring that support for the RZ/V2N SoC is automatically included.

[PATCH 6.12.y-cip 03/11] dt-bindings: soc: renesas: Document SYS for RZ/V2N SoC

[Ovidiu Panait]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

commit dc7af24bd60bdced496d03473e67ce5eb51236a5 upstream.

Add the RZ/V2N (R9A09G056) variant to the existing RZ/V2H(P) System
Controller (SYS) binding, as both IPs are very similar.

However, they have different SoC IDs, and the RZ/V2N does not have
PCIE1 configuration registers, unlike the RZ/V2H(P) SYS IP. To handle
these differences, introduce a new compatible string
`renesas,r9a09g056-sys`.

[PATCH 6.12.y-cip 05/11] dt-bindings: serial: renesas: Document RZ/V2N SCIF

[Ovidiu Panait]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

commit 5eb2d4b3e9a19f08e0ccbb81e0fbfa61de229345 upstream.

Document SCIF bindings for the Renesas RZ/V2N (a.k.a R9A09G056) SoC.
The SCIF interface in Renesas RZ/V2N is identical to the one available
in RZ/V2H(P), so `renesas,scif-r9a09g057` will be used as a fallback,
allowing reuse of the existing driver without modifications.

Add SDHI bindings for the Renesas RZ/V2N (a.k.a R9A09G056) SoC. Use
`renesas,sdhi-r9a09g057` as a fallback since the SD/MMC block on
RZ/V2N is identical to the one on RZ/V2H(P), allowing reuse of the
existing driver without modifications.

[PATCH 6.12.y-cip 07/11] dt-bindings: clock: renesas: Document RZ/V2N SoC CPG

[Ovidiu Panait]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

commit c04269c02273b24398590398c0b73605c72f17ac upstream.

Document the device tree bindings for the Renesas RZ/V2N (R9A09G056)
SoC Clock Pulse Generator (CPG).

Update `renesas,rzv2h-cpg.yaml` to include the compatible string for
RZ/V2N SoC and adjust the title and description accordingly.

Additionally, introduce `renesas,r9a09g056-cpg.h` to define core clock
constants for the RZ/V2N SoC. Note the existing RZ/V2H(P) family-specific
clock driver will be reused for this SoC.

[PATCH 6.12.y-cip 08/11] clk: renesas: rzv2h: Add support for RZ/V2N SoC

[Ovidiu Panait]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

commit f6462eb04f24447e3f9cc33071bbcb888f521985 upstream.

The clock structure for RZ/V2N is almost identical to RZ/V2H(P) SoC
with less IP blocks compared to RZ/V2H(P). For eg: CRU2/3 are present
only on the RZ/V2H(P) SoC.

Add minimal clock and reset entries required to boot the Renesas
RZ/V2N EVK and binds it with the RZ/V2H CPG family driver.

[PATCH 6.12.y-cip 09/11] arm64: dts: renesas: Add initial SoC DTSI for RZ/V2N

[Ovidiu Panait]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

commit 74e252ac272df5a1b468ebf9fb72a25dc38b9b1b upstream.

Add the initial Device Tree Source Include (DTSI) file for the Renesas
RZ/V2N (R9A09G056) SoC. Include support for the following components:
  - CPU (Cortex-A55 cores with operating points)
  - External clocks (audio, qextal, rtxin)
  - Pin controller (GPIO support)
  - Clock Pulse Generator (CPG)
  - System controller (SYS)
  - Serial Communication Interface (SCIF)
  - Secure Digital Host Interface (SDHI 0/1/2)
  - Generic Interrupt Controller (GIC)
  - ARMv8 timer

[PATCH 6.12.y-cip 10/11] arm64: dts: renesas: Add initial device tree for RZ/V2N EVK

[Ovidiu Panait]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

commit 1a42724ac93535a3aa23a60cbb89ce2635b5075c upstream.

Add the initial device tree for the Renesas RZ/V2N EVK board, based on
the R9A09G056N48 SoC. Enable basic board functionality, including:
  - Memory mapping (reserve the first 128MB for the secure area)
  - Clock inputs (QEXTAL, RTXIN, AUDIO_EXTAL)
  - PINCTRL configurations for peripherals
  - Serial console (SCIF)
  - SDHI1 with power control and UHS modes

Update the Makefile to include the new DTB.

[PATCH 6.12.y-cip 11/11] arm64: dts: renesas: Add CN15 eMMC and SD overlays for RZ/V2H and RZ/V2N EVKs

[Ovidiu Panait]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

commit 3d6c2bc7629c8b1bfd75416767122096bb75ba7b upstream.

Introduce device tree overlays for supporting the eMMC (RTK0EF0186B02000BJ)
and microSD (RTK0EF0186B01000BJ) sub-boards connected via the CN15
connector on the RZ/V2H and RZ/V2N evaluation kits.

These overlays enable SDHI0 with appropriate pin control settings, power
regulators, and GPIO handling. Both sub-boards are supported using shared
overlay files that can be applied to either EVK due to their identical
connector layout and interface support.

To support this, new DT overlay files are added:
- `rzv2-evk-cn15-emmc.dtso` for eMMC
- `rzv2-evk-cn15-sd.dtso` for microSD

Additionally, the base DTS files for both EVKs are updated to include a
fixed 1.8V regulator (`reg_1p8v`) needed by the eMMC sub-board and
potential future use cases such as HDMI output.

This confused me, because the overlays are not here, but we already
have them in tree, so we should be ok.

While comments from 6.1 apply, I don't believe they should block
merge. So I can apply this if it passes testing and there are no other
comments.
