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

Hi All,

Extend hardware support on Renesas RZ/T2H and RZ/N2H SoCs and evaluation
boards. Below are the features added for the RZ/T2H and RZ/N2H SoCs and
EVKs:
- Enable I2C0 and I2C1 support
- Enable EEPROM on I2C0
- Enable LEDs on RZ/T2H and RZ/N2H EVKs.
- Enable MMC on RZ/T2H and RZ/N2H EVKs.
- Enable MicroSD card slot on RZ/T2H and RZ/N2H EVKs.
- Enable SD card slot on RZ/T2H and RZ/N2H EVKs.

Note, patches apply on top of [0]
[0] https://web.git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-devel.git/log/?h=renesas-dts-for-v6.18

v1->v2:
- Dropped patches which are already applied from v1 in
  the renesas-dts-for-v6.18 branch
- Dropped RZN2H_PORT_PINMUX and RZN2H_GPIO macros
- Added Reviewed-by tag from Geert
- Changed led node names
- Added color/function/function-enumerator properties
- Replaced GPIO_ACTIVE_LOW with GPIO_ACTIVE_HIGH
- Moved header file inclusions to common dtsi
- Updated switch settings for led-9
- Replaced RZN2H_PORT_PINMUX with RZT2H_PORT_PINMUX
- Corrected switch settings for I2C1
- Added comment regarding DSW17 settings
- Dropped sd0-emmc-prefixes
- Added alias for mmc1
- Dropped sd1-prefixes
- Dropped sd0-sd-prefixes
- Dropped DATA4-7 from data-pins

v1: https://lore.kernel.org/all/20250812200344.3253781-1-prabhakar.mahadev-lad.rj@bp.renesas.com/

[PATCH v2 2/9] arm64: dts: renesas: r9a09g077m44-rzt2h-evk: Add user LEDs

[Prabhakar]

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

Add USER LED0-LED8, which are available on RZ/T2H EVK.

In addition, the header file inclusion has been moved into the common
rzt2h-n2h-evk-common.dtsi so that both RZ/T2H and RZ/N2H EVK DTS/I files
share the same set of bindings. This avoids duplication and keeps the
board files consistent.

[PATCH v2 7/9] arm64: dts: renesas: rzt2h/rzn2h: Enable eMMC

[Prabhakar]

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

Enable eMMC on RZ/T2H and RZ/N2H EVKs. As SDHI0 can be connected to
either eMMC0/SD0 `SD0_EMMC` macro is added.
