From 585a60f24bf86671b17ca7420e82b9404ff18502 Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Fri, 29 Jan 2016 14:49:24 -0800 Subject: clk: imx: return correct frequency for Ethernet PLL The i.MX 7 designs Ethernet PLL provides a 1000MHz reference clock. Store the reference clock in the clk_pllv3 structure according to the PLL type.
