From 435ee357e9c4e09032e4919b4b815fce1fc7d555 Mon Sep 17 00:00:00 2001 From: Jitao Shi Date: Tue, 1 Jun 2021 11:42:27 +0800 Subject: soc/mediatek/mt8195: add power and power control for eDP 1. Add API of TVD_PLL1 mt_pll_set_tvd_pll1_freq() for setting rate. 2. Add API of TVD_PLL1 edp_mux_set_sel() for mux sel. 3. Add eDP power domain control.
