Subject: [PATCH v11 4/4] G45 TWI: remove open drain setting for twi function gpios
Date: Tue, 8 Nov 2011 12:11:03 +0100 [thread overview]
Message-ID: <b56adb1bfd2c2188d759ee9cbd5f38208e561667.1346225321.git.n.voss@weinmann.de> (raw)
In-Reply-To: <cover.1346225321.git.n.voss@weinmann.de>
The G45 datasheets explicitly states that setting the open drain property
on peripheral function gpios is not allowed. (How about other A91 chips?)
