Subject: [U-Boot] [PATCH 1/3] gpio: Build the da8xx_gpio code for the davinci644x device
Date: Fri, 18 Jan 2013 16:19:48 +0100 [thread overview]
Message-ID: <1358522390-10161-1-git-send-email-holger@freyther.de> (raw)
The differences include the number of GPIOs and that one is
not required to set the pinmux on request.
