From 26b2c68b61764cc743e9684727c6b124a4201cc2 Mon Sep 17 00:00:00 2001 From: Harini Katakam <harini.katakam@xilinx.com> Date: Wed, 13 Mar 2019 19:41:19 +0530 Subject: [PATCH] arm64: zynqmp: dt: Add optional gpio phy reset properties Add gpio phy reset via I2C expander TCA6416 on board ZCU102. A warning call trace is observer in probe when this reset is called from context that can sleep. Keep this commented until that is resolved in phylib.
