Subject: [PATCH v2 4/5] MIPS: XBurst: fix the JZ4755's clocksource input frequency value
Date: Thu, 28 Jun 2012 22:32:33 +0400 [thread overview]
Message-ID: <1340908354-17895-5-git-send-email-antonynpavlov@gmail.com> (raw)
In-Reply-To: <1340908354-17895-1-git-send-email-antonynpavlov@gmail.com>
The 40 KHz frequency value was used to parry
__lshrdi3() error on little-endian MIPS because
the __lshrdi3() function is used in clocksource code.
The true value of the JZ4755's external clock frequency is 24 MHz.
