[PATCH] arm64: dts: zii-ultra: add PCIe PHY supply
From: Lucas Stach <l.stach@pengutronix.de>
Date: 2021-08-20 22:46:05
The ZII Ultra board uses the same design as the EVK board supplying PCIE_VPH with 3.3V. Add this connection to the DT to allow the PCIe driver to enable the internal PHY regulator, as required by the reference manual.
