From 4a453314883d9d0a500107b508500ffffdca2f6d Mon Sep 17 00:00:00 2001 From: Rahul Sharma Date: Thu, 25 Jul 2013 10:37:34 +0530 Subject: [PATCH] clk/exynos5250: add mout_hdmi mux clock for hdmi hdmi driver needs to change the parent of hdmi clock frequently between pixel clock and hdmiphy clock. hdmiphy is not stable after power on and for a short interval while changing the phy configuration. For this duration pixel clock is used to clock hdmi. This patch is exposing the mux for changing parent.
