Subject: [PATCH v8 01/10] clk: fix initial state of critical clock's parents
Date: Tue, 17 May 2016 13:05:02 +0800	[thread overview]
Message-ID: <1463461511-25019-2-git-send-email-erin.lo@mediatek.com> (raw)
In-Reply-To: <1463461511-25019-1-git-send-email-erin.lo@mediatek.com>

From: James Liao <jamesjj.liao@mediatek.com>

This patch fixed wrong state of parent clocks if they are registered
after critical clocks.
