From 65d833038e27656f881f8902289152879a5c3d99 Mon Sep 17 00:00:00 2001 From: Philipp Tomsich Date: Fri, 24 Mar 2017 19:24:25 +0100 Subject: [PATCH] rockchip: clk: rk3399: add clocking support for Ethernet The Ethernet driver for the RK3288/3399 GMAC makes sure that the clock is ungated through a call to clk_set_rate(...). Even though nothing needs to be done on the RK3399 (the clock gates are open and the clock is external), we need to implement enough support to at least return success to enable driver probing.
