From 628550e2b4a9499ae92222a2e2c5902c456a56ef Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Sat, 21 Aug 2021 00:44:02 +0200 Subject: [PATCH] arm64: dts: zii-ultra: add PCIe PHY supply 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.
