Subject: [PATCH 4/4] gpu: drm: exynos_hdmi: Use consolidated function on binding PHY DT property
Date: Tue, 23 Aug 2016 18:13:39 +0900	[thread overview]
Message-ID: <1471943619-6102-5-git-send-email-woogyom.kim@gmail.com> (raw)
In-Reply-To: <1471943619-6102-1-git-send-email-woogyom.kim@gmail.com>

Handle legacy and raw 'phy' parsing in single function.
And it also removes goto condition.
