From 554f269f0f384d34f7e8052242df3b97be325924 Mon Sep 17 00:00:00 2001 From: Gayatri Kammela Date: Thu, 12 Dec 2019 10:38:47 -0800 Subject: [PATCH] platform/x86: intel_pmc_core: Add Intel Elkhart Lake support Add Intel Elkhart Lake to the list of the platforms that driver supports for the PMC device. Just like Ice Lake and Tiger Lake, Elkhart Lake can also reuse all the Cannon Lake PCH IPs. Also, it uses the same PCH IPs of Tiger Lake, no additional effort is needed to enable but to simply reuse them.
