From a64bb9cda8b12f599766c7dfe81770d2082a133a Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Tue, 21 Dec 2010 21:05:14 -0700 Subject: OMAP4: powerdomains: add PRCM partition data; use OMAP4 PRM functions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit OMAP4 powerdomain control registers are split between the PRM hardware module and the PRCM_MPU local PRCM. Add this PRCM partition information to each OMAP4 powerdomain record, and convert the OMAP4 powerdomain function implementations to use the OMAP4 PRM instance functions. Also fixes a potential null pointer dereference of pwrdm->name. The autogeneration scripts have been updated.
