From 508dc163f183f99f4683365ef3a6443658979846 Mon Sep 17 00:00:00 2001 From: Lean Sheng Tan Date: Wed, 16 Jun 2021 01:32:22 -0700 Subject: soc/intel/common: Move PMC EPOC related code to Intel common code Move PMC EPOC related code to intel/common/block because it is generic for most Intel platforms and ADL, TGL & EHL use it. Add a kconfig 'PMC_EPOC' to guard this common EPOC code. The PMC EPOC register indicates which external crystal oscillator is connected to the PCH. This frequency is important for determining the IP clock of internal PCH devices.
