From e39eed8f476b6f8861318fc122b546158edce259 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Mon, 10 Sep 2018 12:58:36 +0900 Subject: [PATCH] ARM: uniphier: remove ad-hoc clock enabling for EHCI The MIO clock is enabled by default, and the STDMAC clock is enabled by the clk driver. The ad-hoc way to enable the clock is no longer needed.
