From ecd0cec04ca672b9ca8d003ef2a07429f7d4c101 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Wed, 4 Apr 2018 01:31:20 +0100 Subject: [PATCH] net: sun8i-emac: remove support for old binding The original DT binding used by U-Boot's sun8i-emac driver was not really agreed upon, and deviated from the "official" binding now used by the kernel. Since now all U-Boot users have been converted to the new binding, we can remove support for the old DT nodes from the driver.
