Subject: [PATCH] i2c: i801: Add support for Intel Comet Lake PCH-V
Date: Thu, 16 Jan 2020 09:46:51 +0200 [thread overview]
Message-ID: <20200116074651.529380-1-jarkko.nikula@linux.intel.com> (raw)
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.
