Subject: [PATCHv8 17/18] I2C: OMAP: Do not set the XUDF if the underflow is not reached
Date: Thu, 12 Apr 2012 18:36:34 +0530 [thread overview]
Message-ID: <1334235995-6727-18-git-send-email-shubhrajyoti@ti.com> (raw)
In-Reply-To: <1334235995-6727-1-git-send-email-shubhrajyoti-l0cyMroinI0@public.gmane.org>
Currently in the 1.153 errata handling while waiting for transmitter
underflow if NACK is got the XUDF flag is also set.
The flag is set after wait for the condition is over.
