Subject: [PATCH v2 2/3] [media] atmel-isi: convert the pdata from pointer to structure
Date: Tue, 25 Mar 2014 18:41:27 +0800	[thread overview]
Message-ID: <1395744087-5753-3-git-send-email-josh.wu@atmel.com> (raw)
In-Reply-To: <1395744087-5753-1-git-send-email-josh.wu@atmel.com>

Now the platform data is initialized by allocation of isi
structure. In the future, we use pdata to store the dt parameters.

Signed-off-by: Josh Wu <josh.wu@atmel.com>

v1 --> v2:
 no change.
