Subject: [PATCH 4/6] ARM: dts: i.MX27: Increase "clock-latency" value
Date: Sat, 20 Jul 2013 11:17:57 +0400 [thread overview]
Message-ID: <1374304679-27338-4-git-send-email-shc_work@mail.ru> (raw)
In-Reply-To: <1374304679-27338-1-git-send-email-shc_work@mail.ru>
i.MX27 CPU can be clocked with a 32 kHz quartz, and not just 32768 Hz,
so increase "clock-latency" value, which will ensure that we use two
clock cycles on frequency change.
