Subject: [PATCH v3 03/16] clk: sunxi-ng: h3: h5: Allow some clocks to set parent rate
Date:   Thu,  1 Mar 2018 22:34:29 +0100
Message-Id: <20180301213442.16677-4-jernej.skrabec@siol.net>
In-Reply-To: <20180301213442.16677-1-jernej.skrabec@siol.net>
References: <20180301213442.16677-1-jernej.skrabec@siol.net>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Some units have to be able to set it's own clock precisely to work
correctly. Allow them to do so by adding CLK_SET_RATE_PARENT flag.

Add this flag to DE, TCON and HDMI clocks.
