From f53938d2c79ae3c768dc92b1c3d898dfe820a491 Mon Sep 17 00:00:00 2001 From: Jarkko Nikula Date: Thu, 16 Jan 2020 09:46:51 +0200 Subject: i2c: i801: Add support for Intel Comet Lake PCH-V Add support for Intel Comet Lake PCH-V which is based on Intel Kaby Lake. Difference between it and other Comet Lake variants is that former uses previous iTCO version 4 and latter use version 6 like Intel Cannon Lake PCH.
