[PATCH v2 0/7] Enable Ethernet and SDHI on RZ/G2UL SMARC EVK

[Biju Das]

This patch series aims to enable Ethernet and SDHI on RZ/G2UL
SMARC EVK. This patches also adds pinctrl support to SoC
dtsi and enables scif0 and audio clk pins.

This patch series depend upon [1], [2], [3]  and [4]
[1] https://patchwork.kernel.org/project/linux-renesas-soc/list/?series=628396

[4] https://patchwork.kernel.org/project/linux-renesas-soc/patch/20220401175427.19078-1-biju.das.jz@bp.renesas.com/

v1->v2:
 * Added Rb tag from Geert
 * Updated gpios property for vccq_sdhi1 regulator and removed
   sdhi1 node as it is enabled in common.

[PATCH v2 5/7] arm64: dts: renesas: rzg2ul-smarc: Enable microSD on SMARC platform

[Biju Das]

Enable the microSD card slot connected to SDHI1 on the RZ/G2UL SMARC
platform by removing the sdhi1 override which disabled it, and by adding
the necessary pinmux required for SDHI1.

This patch also adds gpios property to vccq_sdhi1 regulator.

RZ/G2UL SoM has both 64GB eMMC and microSD connected to SDHI0.

Both these interfaces are mutually exclusive and the SD0 device
selection is based on SW1[2] on SoM module.

Set SW1[2] to position OFF for selecting eMMC

[PATCH v2 7/7] arm64: dts: renesas: rzg2ul-smarc-som: Enable Ethernet on SMARC platform

[Biju Das]

Enable Ethernet{0,1} interfaces on RZ/G2UL SMARC EVK.

Ethernet0 pins are muxed with CAN0, CAN1, SSI1 and RSPI1 pins and Ethernet0
device selection is based on the SW1[3] switch position.

Set SW1[3] to position OFF for selecting CAN0, CAN1, SSI1 and RSPI1.
Set SW1[3] to position ON for selecting Ethernet0.

This patch disables Ethernet0 on RZ/G2UL SMARC platform by default.
