Subject: [PATCH 2/3 v4] spi: s3c64xx: for DT platofrms always get the chipselect info from DT node
Date: Thu, 12 Jun 2014 18:43:40 +0530	[thread overview]
Message-ID: <1402578821-27338-2-git-send-email-ch.naveen@samsung.com> (raw)
In-Reply-To: <1402578821-27338-1-git-send-email-ch.naveen@samsung.com>

Use controller_data structure only for the Non Device tree  platforms.
For Device tree platforms, always derive the chipselect info from
DT node.
