From 56868deece922283b367d08f1d647726d5b307d9 Mon Sep 17 00:00:00 2001 From: Joachim Eastwood Date: Sun, 1 May 2016 22:58:20 +0200 Subject: [PATCH] stmmac: dwmac-socfpga: add PM ops and resume function Implement the needed PM callbacks in the driver instead of relying on the init/exit hooks in stmmac_platform. This gives the driver more flexibility in how the code is organized. Eventually the init/exit callbacks will be deprecated in favor of the standard PM callbacks and driver remove function.
