From 555ceca0886ccf24116bd32f3b5fc550ef592188 Mon Sep 17 00:00:00 2001 From: Mark Kettenis Date: Sun, 30 Jun 2019 18:01:53 +0200 Subject: [PATCH] rockchip: clk: rk3399: handle clk_enable requests for USB3 The "simple" OF glue layer for the Designware USB3 core enables all refernced clocks. These need to be need to be implemented otherwise the driver fails to probe. A dummy implementation that simply returns success is sufficient since the RK3399 comes out of reset with all clock gates open.
