From 0c3492467c99f3d0d83a48012ee6e672b016759c Mon Sep 17 00:00:00 2001 From: Santosh Shilimkar Date: Mon, 27 Sep 2010 14:02:57 -0600 Subject: omap4: control: Add ctrl_pad_base to omap_globals On omap4 control module is divided in four IP blocks. - CTRL_MODULE_CORE 0x4a002000 - CTRL_MODULE_PAD_CORE 0x4a100000 - CTRL_MODULE_WKUP 0x4a30c000 - CTRL_MODULE_PAD_WKUP 0x4a31e000 Addressing all the modules with single base address is not possible considering 16 bit offsets. The mux code manages the pad core and pad wakeup related base address inside the mux framework. For other usage only control core and control pad bases are necessary. So this patch maps only needed pad control base address which is used by device drivers and infrastructure code The main control core base is still kept same in this patch to keep git-bisect working. This will be fixed in the relevant patch in this series.

To ensure that git bisect work across commits, all changes are clubbed together 1. Move the common control base address to control core 2. Remove the manually coeded defines and use the ones from headers. 3. Fix the the status register define in id.c for OMAP4 4. Fix all the register define in hsmmc.c 5.
