From 2ad7b7560fd586a8b72eb52df9483c203943eec9 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Wed, 9 Dec 2015 19:39:03 +0100 Subject: [PATCH] Doc: Micrel-ksz90x1.txt: Document deprecated MAC OF properties Phy properties are expected to be found in the PHY OF node. However this Micrel driver also allows them to be placed into the MAC OF node. This is deprecated. Document it as such, and remove the example using the deprecated method to prevent people copying it into new device tree files.
