[PATCH v3 0/5] dt-bindings: usb: atmel: convert Atmel USB controller bindings to YAML

[Charan Pedumuru]

This patch series converts the legacy text-based Device Tree bindings for
Atmel/Microchip USB controllers to DT schema (YAML) format.

Note:
The patch "dt-bindings: usb: atmel,at91sam9rl-udc: convert to DT schema"
depends on the patch "arm: dts: at91: remove unused #address-cells/#size-cells
from sam9x60 UDC node". If the DT schema patch is applied before the DTS
cleanup patch, `dtbs_check` will fail due to the presence of the removed
properties in the existing DTS.

Changes in v3:
- sam9x60: Add a new patch removing the unnecessary #address-cells and
  #size-cells properties from the sam9x60 UDC node.
- atmel,at91sam9rl-udc: Remove #address-cells and #size-cells from the
  atmel,at91sam9rl-udc binding properties.
- generic-ohci: Add an else condition to the generic-ohci schema properties
  for improved validation precision.
- Link to v2: https://lore.kernel.org/r/20260224-atmel-usb-v2-0-6d6a615c9c47@xxxxxxxxx

Changes in v2:
- Drop the separate YAML patches for OHCI and EHCI.
- Add the compatibles "atmel,at91rm9200-ohci" and "atmel,at91sam9g45-ehci"
  to the existing generic OHCI and EHCI binding files.
- Link to v1: https://lore.kernel.org/r/20260201-atmel-usb-v1-0-d1a3e93003f1@xxxxxxxxx
