From: Philipp Zabel Date: Mon, 30 Nov 2015 21:07:53 +0000 (+0100) Subject: clk: mediatek: Add hdmi_ref HDMI PHY PLL reference clock output X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=4585945bf1d348d006f7270beea3dae09fee3413;p=openwrt%2Fstaging%2Fblogic.git clk: mediatek: Add hdmi_ref HDMI PHY PLL reference clock output 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.
