Subject: [PATCH v13 11/14] clk: mediatek: Add hdmi_ref HDMI PHY PLL reference clock output
Date: Tue, 8 Mar 2016 14:27:26 +0100 [thread overview]
Message-ID: <1457443649-12133-12-git-send-email-p.zabel@pengutronix.de> (raw)
In-Reply-To: <1457443649-12133-1-git-send-email-p.zabel@pengutronix.de>
The configurable hdmi_ref output of the PLL block is derived from
the tvdpll_594m clock signal via a configurable PLL post-divider.
It is used as the PLL reference input to the HDMI PHY module.
