From b30fe36734df3c48ec35438052ee8b28bf7a6a44 Mon Sep 17 00:00:00 2001 From: Srinidhi N Kaushik Date: Wed, 20 May 2020 11:55:36 -0700 Subject: soc/intel/tigerlake: Remove MIPI clock setting from devicetree In Tiger Lake we have support for enabling MIPI clocks at runtime in ACPI. Hence remove setting pch_islclk from devcietree and chip.h. Also update functions which reference pch_isclk.
