Subject: [PATCHv2 3/3] s5p-tv: hdmi: use hdmiphy as PHY
Date: Tue, 08 Apr 2014 16:37:36 +0200

In-reply-to: <1396967856-27470-1-git-send-email-t.stanislaws@samsung.com>
References: <1396967856-27470-1-git-send-email-t.stanislaws@samsung.com>
Sender: linux-kernel-owner@vger.kernel.org

The HDMIPHY (physical interface) is controlled by a single
bit in a power controller's regiter. It was implemented
as clock. It was a simple but effective hack.

This patch makes S5P-HDMI driver to control HDMIPHY via PHY interface.
