Subject: [PATCH v5] arm64: dts: mt8173: add mmsel clocks for 4K support
Date: Thu, 4 Aug 2016 10:57:18 +0800 [thread overview]
Message-ID: <1470279438-60372-1-git-send-email-bibby.hsieh@mediatek.com> (raw)
To support HDMI 4K resolution, mmsys need clcok
mm_sel to be 400MHz.
The board .dts file should override the clock rate
property with the higher VENCPLL frequency the board
supports HDMI 4K resolution.
