From fc6634ac0e5380aeb1063275a2e9a583d41b2306 Mon Sep 17 00:00:00 2001 From: Bibby Hsieh Date: Thu, 4 Aug 2016 10:57:18 +0800 Subject: [PATCH] arm64: dts: mt8173: add mmsel clocks for 4K support 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.
