Subject: [PATCH 01/18] platform_data: edma: Be precise with the paRAM struct
Date: Thu, 13 Mar 2014 11:18:23 +0200 [thread overview]
Message-ID: <1394702320-21743-2-git-send-email-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <1394702320-21743-1-git-send-email-peter.ujfalusi@ti.com>
The edmacc_param struct should follow the layout of the paRAM area in the
HW. Be explicit on the size of the fields (u32) and also mark the struct
as packed to avoid any padding on non 32bit architectures.
