Subject: [RFC PATCH v2 05/14] x86/hpet: Relocate flag definitions to a header file
Date: Wed, 27 Feb 2019 08:05:09 -0800 [thread overview]
Message-ID: <1551283518-18922-6-git-send-email-ricardo.neri-calderon@linux.intel.com> (raw)
In-Reply-To: <1551283518-18922-1-git-send-email-ricardo.neri-calderon@linux.intel.com>
Users of HPET timers (such as the hardlockup detector) need the definitions
of these flags to interpret the configuration of a timer as passed by
platform code.
