Subject: [PATCH 5/5] pcmcia: sa1111: make use of device clock
Date: Tue, 12 Nov 2013 07:32:12 +0400 [thread overview]
Message-ID: <1384227132-10501-5-git-send-email-dbaryshkov@gmail.com> (raw)
In-Reply-To: <1384227132-10501-1-git-send-email-dbaryshkov@gmail.com>
Use per-device clock (instead of calling cpufreq_get(0), which can
return 0 if no cpu frequency driver is selected) to program timings.
