[PATCH v7 0/2] usb: dwc3: add Altera Agilex5 DWC3 support

[adrian.ho.yin.ng@altera.com]

From: Adrian Ng Ho Yin <adrian.ho.yin.ng@altera.com>

Agilex5 integrates a Synopsys DesignWare USB3 controller that is probed
through dwc3-generic-plat. This series adds:

1. dt-bindings for compatible "altr,agilex5-dwc3"
2. matching entry in dwc3-generic-plat

arm64 DTS enablement is posted separately.

changelog:
v6->v7:
* Drop arm64 DTS patches from this series (DTS must not be mixed into a
  USB-targeted series). DTS is reposted separately.

v6 patch link:
https://lore.kernel.org/all/cover.1788886615.git.adrian.ho.yin.ng@altera.com/

v5->v6:
* Make snps,dis_u2_susphy_quirk and snps,dis_u3_susphy_quirk required.

v5 patch link:
https://lore.kernel.org/all/cover.1788757821.git.adrian.ho.yin.ng@altera.com/

v4->v5:
* Binding: replace unevaluatedProperties: false with additionalProperties:
  false, and allow only the extra DWC3 properties used on this SoC via
  "foo: true".

v4 patch link:
https://lore.kernel.org/all/cover.1788503540.git.adrian.ho.yin.ng@altera.com/

v3->v4:
* Drop clk binding/driver patches; reuse AGILEX5_USB31_SUSPEND_CLK for
  both "ref" and "suspend".
* Update altr,agilex5-dwc3.yaml per review.
* Limit the series to USB binding, DTS, and dwc3-generic-plat.

v3 patch link:
https://lore.kernel.org/all/cover.1786518803.git.adrian.ho.yin.ng@altera.com/

v2->v3:
* Drop dma_addressable_bits; describe 40-bit DMA limit with dma-ranges.
* Keep Agilex5 support in dwc3-generic-plat as a compatible match only.

v2 patch link:
https://lore.kernel.org/all/cover.1765249127.git.adrianhoyin.ng@altera.com/

v1->v2:
* Flattened model + dwc3-generic-plat instead of dwc3-of-simple.
* Split USB3 add vs USB0 disable in DTS (still wrongly kept in USB
  series until v7).

v1 patch link:
