From b7e312dea1d8378b8f311ce9096759b5accb1939 Mon Sep 17 00:00:00 2001 From: Trent Piepho Date: Tue, 5 Feb 2019 00:17:39 +0000 Subject: dt-bindings: imx6q-pcie: Add description of imx7d pcie phy There is a separate PHY device with its own registers on imx7d. It's currently unused, but a PCIe erratum on imx7d will require it for the workaround.
