From e8b595f7b058c7909e410f3e0736d95e8f909d01 Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Mon, 4 Jul 2022 19:11:47 +0300 Subject: [PATCH] drm/msm/hdmi: make hdmi_phy_8996 OF clk provider On MSM8996 the HDMI PHY provides the PLL clock to the MMCC. As we are preparing to convert the MSM8996 to use DT clocks properties (rather than global clock names), register the OF clock provider. While we are at it, also change the driver to use clk_parent_data rather parent_names to setup a link to the XO clock.
