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.
