Subject: [PATCH 3/7] HPET: allow non-power-of-two frequencies
Date: Wed, 28 Sep 2005 09:12:16 +0200 (MEST) [thread overview]
Message-ID: <20050928071216.23025.43840.balrog@turing> (raw)
In-Reply-To: <20050928071155.23025.43523.balrog@turing>
It was only the RTC hardware that restricted interrupt frequencies to a
power of two. There is no reason to take over this restriction into the
HPET driver, so remove the offending check.
