From 55d8a65308a5099155683c5a9bba3b8577988111 Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Tue, 8 Dec 2009 16:18:47 -0700 Subject: OMAP2/3: move SDRC macros to mach-omap2/sdrc.h clock34xx.c contains some macros which probably belong in mach-omap2/sdrc.h. Move those macros to mach-omap2/sdrc.h.

Instead, define the data in a .c file. Russell King proposed this new arrangement: http://marc.info/?l=linux-omap&m=125967425908895&w=2 This patch also deals with most of the flagrant checkpatch violations. While here, separate the prcm_config data structures out into their own files, opp2xxx.h and opp24{2,3}0_data.c, and only build in the OPP tables for the target device. This should save some memory. In the long run, these prcm_config tables should be replaced with OPP code.
