Subject: [PATCH 3/3] i2c-omap: Enable workaround for Errata 1.153 based on
Date: Thu, 20 Aug 2009 11:21:16 -0500 [thread overview]
Message-ID: <1250785276-31713-4-git-send-email-m-sonasath@ti.com> (raw)
In-Reply-To: <1250785276-31713-3-git-send-email-m-sonasath-l0cyMroinI0@public.gmane.org>
Silicon Errata 1.153 has been fixed on OMAP 3630|4430 with the use of a later
version of I2C IP block.
The errata impacts OMAP 2420|2430|3430, enable the workaround for these based
on I2C IP block revision number instead of OMAP CPU type
