From 2804ba4edef5b4de01d4c580eb9ab4000f822a53 Mon Sep 17 00:00:00 2001 From: Jisheng Zhang Date: Wed, 20 Jan 2016 19:27:23 +0800 Subject: [PATCH] net: mvneta: Try to get named core clock first Some platforms may provide more than one clk for the mvneta IP, for example Marvell BG4CT provides one clk for the mac core, and one clk for the AXI bus logic. To support for more than one clock, we'll need to distinguish between the clock by name. Change clock probing to first try to get "core" clock before falling back to unnamed clock.
