This obsolete binding is (and won't be) supported for STM32MP15x variant of dwc_eth_qos driver.

I am currenty upstream the support in U-boot of the support of the final binding
aligned with Kernel one.

"net: dwc_eth_qos: implement reset-gpios for stm32"
http://patchwork.ozlabs.org/patch/1257377/

=> phy-handle and "reset-gpios" in sub node PHY
