Dear All,

This patch series adds USB2.0 support for the Renesas R9A09G047 SoC and
enables it on the RZ/G3E SMARK II board.

Kind regards,
Tommaso

The USB2.0 wiring on the RZ SMARC Carrier-II board is the same for the
RZ/G3E and RZ/G3L SoMs, so the nodes belong in the shared
renesas-smarc2.dtsi. Enabling them there breaks the RZ/G3L SMARC EVK
build, as the r9a08g046 (RZ/G3L) SoC DTSI describes neither the USB2.0
host (OHCI/EHCI) nor function (HSUSB) instances:

Error: arch/arm64/boot/dts/renesas/renesas-smarc2.dtsi:94.1-7 Label or path ehci0 not found

Add minimal placeholder nodes carrying only the reg property.
The remaining properties will be filled in once USB2.0 support for
RZ/G3L is complete.

Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:
- [Medium] Placeholder DT nodes omit mandatory properties (e.g. `compatible`), causing schema validation failures.
- [Low] Newly added USB device tree nodes are not sorted by unit-address.

commit cc298f15a0f37ec626ccaf22949b2e2fb488034f
Author: Tommaso Merciai <tommaso.merciai.xr@bp.renesas.com>

arm64: dts: renesas: r9a08g046: Add USB2.0 placeholder nodes

This commit adds placeholder USB2.0 devicetree nodes to the RZ/G3L SoC DTSI.
It resolves build errors caused by the shared SMARC Carrier-II board file
enabling these nodes. The nodes currently only contain the reg property.

[Severity: Medium]
Will these placeholder nodes cause devicetree schema validation failures?

Since they omit mandatory properties like compatible strings, compiling the
devicetree with dtbs_check enabled might produce structurally invalid nodes.
Because the shared board file enables them, they could be treated as malformed
active devices. Could the basic required properties be included now?

[Severity: Low]
This isn't a bug, but should these nodes be sorted by their unit-address?

The ohci1 node at usb@11e90000 is placed before ehci0 at usb@11e10100, which
breaks the ascending numerical address ordering convention. Sorting them as
usb@11e10000, usb@11e10100, usb@11e30000, pcie@11e40000, usb@11e90000, and
usb@11e90100 might be preferred.

The Renesas RZ/G3E ("R9A09G047") SoC supports 1x channel with OTG/DRD
and 1x channel with host interface.

Add the EHCI, OHCI, USB2.0 PHY and reset control nodes for USB2.0 channels
in R9A09G047 SoC DTSI.

[Severity: Low]
This isn't a bug, but should these newly added device tree nodes be sorted by
their unit-address?

The new nodes (starting with usb@15800000) are appended after the existing
usb-phy@15870000 node, which breaks the ascending unit-address order.

Additionally, within the new block itself, the nodes appear to be grouped by
peripheral type rather than being sorted numerically by their unit-address,
resulting in usb@15810000 being placed before usb@15800100.

Enable USB2.0 support on the RZ/G3E EVK board. The USB1B_1A_HOST and
USB5_4_HOST connectors support host operation only, while USB0_OTG
supports both host and peripheral operation.
