Subject: [PATCH 04/17] mfd: dbx500-prcmu: Introduce TCDM mapping struct
Date: Wed, 5 Sep 2012 11:59:00 +0200 [thread overview]
Message-ID: <1346839153-6465-5-git-send-email-loic.pallardy-ext@stericsson.com> (raw)
In-Reply-To: <1346839153-6465-1-git-send-email-loic.pallardy-ext@stericsson.com>
TCDM size varies between DBs models.
This patch introduces a new structure aimed to handle the TCDM
dynamically.
Each SoC from ux500 family declares its mapping and pass it to
prcmu early init.
