Subject: [PATCH v3 2/2] x86, tsc: Add missing Baytrail frequency to the table
Date: Thu, 6 Feb 2014 13:49:25 +0200 [thread overview]
Message-ID: <1391687365-10922-2-git-send-email-mika.westerberg@linux.intel.com> (raw)
In-Reply-To: <1391687365-10922-1-git-send-email-mika.westerberg@linux.intel.com>
Intel Baytrail is based on Silvermont core so MSR_FSB_FREQ[2:0] == 0 means
that the CPU reference clock runs at 83.3MHz. Add this missing frequency to
the table.
