From bb4e6ff01ac356f82327d980e45fee8a65491328 Mon Sep 17 00:00:00 2001 From: Nickey Yang Date: Mon, 18 Sep 2017 17:05:37 +0800 Subject: [PATCH] arm64: dts: rockchip: Correct MIPI DPHY PLL clock on rk3399 There is a further gate in between the mipidphy reference clock and the actual ref-clock input to the dsi host, making the clock hirarchy look like clk_24m --> Gate11[14] --> clk_mipidphy_ref --> Gate21[0] --> clk_dphy_pll Fix the clock reference so that the whole clock subtree gets enabled when the dsi host needs it.
