2009-05-25ARM: OMAP2/3: Remove OMAP_PRM_REGADDR and OMAP2_PRM_BASETony Lindgren
Remove OMAP_PRM_REGADDR and use processor specific defines instead. Also fold in a patch from Kevin Hilman to add _OFFSET #defines for the PRCM registers to be used with the prm_[read|write]_* macros. These are used extensively in the forthcoming OMAP PM support. Also remove now unused OMAP2_PRM_BASE. Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2009-02-19[ARM] omap: add support for bypassing DPLLsRussell King
This roughly corresponds with OMAP commits: 7d06c48, 3241b19, 88b5d9b, 18a5500, 9c909ac, 5c6497b, 8b1f0bd, 2ac1da8. For both OMAP2 and OMAP3, we note the reference and bypass clocks in the DPLL data structure. Whenever we modify the DPLL rate, we first ensure that both the reference and bypass clocks are enabled. Then, we decide whether to use the reference and DPLL, or the bypass clock if the desired rate is identical to the bypass rate, and program the DPLL appropriately. Finally, we update the clock's parent, and then disable the unused clocks. This keeps the parents correctly balanced, and more importantly ensures that the bypass clock is running whenever we reprogram the DPLL. This is especially important because the procedure for reprogramming the DPLL involves switching to the bypass clock. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2009-02-08[ARM] OMAP2 SDRC: separate common OMAP2/3 code from OMAP2xxx codePaul Walmsley
Separate SDRC code common to OMAP2/3 from mach-omap2/sdrc2xxx.c to mach-omap2/sdrc.c. Rename the OMAP2xxx-specific functions to use an 'omap2xxx' prefix rather than an 'omap2' prefix, and use "sdrc" in the function names rather than "memory." Mark several functions as static that should not be used outside the sdrc2xxx.c file. linux-omap source commit is bf1612b9d8d29379558500cd5de9ae0367c41fc4.

2009-02-08[ARM] OMAP2 SDRC: rename memory.c to sdrc2xxx.cPaul Walmsley
Rename arch/arm/mach-omap2/memory.c to arch/arm/mach-omap2/sdrc2xxx.c, since it contains exclusively SDRAM-related functions. Most of the functions are also OMAP2xxx-specific - those which are common will be separated out in a following patch. linux-omap source commit is fe212f797e2efef9dc88bcb5db7cf9db3f9f562e.
