From c17133e086994b3626cc373de8ca22cd8d293a0c Mon Sep 17 00:00:00 2001 From: Sekhar Nori Date: Wed, 9 Aug 2017 19:32:47 +0530 Subject: [PATCH] ARM: dts: dra71-evm: workaround incorrect DP83867 RX_CTRL pin strap The DRA71 EVM straps the DP83867 GigaBit Ethernet phy's RX_DV/RX_CTRL pin in mode 1. Unfortunately, the phy data manual disallows this. Add "ti,dp83867-rxctrl-strap-quirk" property to the phy's device-tree node to allow kernel to enable software workaround for this incorrect strap setting. This is as suggested by the phy's datamanual and ensures proper operation of this PHY. This needs to be done for both instances of this PHY present on the board.
