2023-01-09ARM: omap2: simplify clock2xxx headerArnd Bergmann
Only one of the functions in clock2xxx.h is used in a file other than the one it is declared in, so remove the extra declarations, and make the symbols static. Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2017-03-08clk: ti: convert to use proper register definition for all accessesTero Kristo
Currently, TI clock driver uses an encapsulated struct that is cast into a void pointer to store all register addresses. This can be considered as rather nasty hackery, and prevents from expanding the register address field also. Instead, replace all the code to use proper struct in place for this, which contains all the previously used data. This patch is rather large as it is touching multiple files, but this can't be split up as we need to avoid any boot breakage.

2014-05-08ARM: OMAP2+: raw read and write endian fixVictor Kamensky
All OMAP IP blocks expect LE data, but CPU may operate in BE mode. Need to use endian neutral functions to read/write h/w registers. I.e instead of __raw_read[lw] and __raw_write[lw] functions code need to use read[lw]_relaxed and write[lw]_relaxed functions. If the first simply reads/writes register, the second will byteswap it if host operates in BE mode. Changes are trivial sed like replacement of __raw_xxx functions with xxx_relaxed variant.

2013-10-19ARM: OMAP2: CM/PM: remove direct register accesses outside CM codeTero Kristo
Users of the CM funtionality should not access the CM registers directly by themselves. Thus, added new CM driver APIs for the OMAP2 specific functionalities which support the existing direct register accesses, and changed the platform code to use these. This is done in preparation for moving the CM code into its own individual driver. Signed-off-by: Tero Kristo <t-kristo@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>

2012-11-08ARM: OMAP2+: PRCM: split and relocate the PRM/CM globals setupPaul Walmsley
Split omap2_set_globals_prcm() into PRM, CM, and PRCM_MPU variants, since these are all separate IP blocks. This should make it easier to move the PRM, CM, PRCM_MPU code into drivers/ in future patchsets.

2012-11-08ARM: OMAP2xxx: clock: remove global 'dclk' variablePaul Walmsley
Remove the global 'dclk' variable, instead replacing it with a variable local to the dpllcore clock type C file. This removes some of the special-case code surrounding the OMAP2xxx clock init. This patch is a prerequisite for the removal of the omap_prcm_restart() code from arch/arm/mach-omap2/prcm.c. It also cleans up some special-case OMAP2xxx clock code in the process.

2012-10-31ARM: OMAP: Split sram.h to local headers and minimal shared headerTony Lindgren
Most of the defines are specific to omap1 and omap2+, and should be in the local headers. Only minimal function prototypes need to be shared. As discussed on linux-arm-kernel, we want to avoid relative includes for the arch/arm/*omap* shared code: http://www.spinics.net/lists/linux-omap/msg80520.html So this patch re-adds a minimal plat/sram.h. The new plat/sram.h must not be included from drivers, that will break build for omap2+ CONFIG_MULTIPLATFORM. Note that this patch temporarily adds two more relative includes; Those will be removed in the following patch. Signed-off-by: Tony Lindgren <tony@atomide.com>

2010-12-21OMAP2/3: PRCM: split OMAP2/3-specific PRCM code into OMAP2/3-specific filesPaul Walmsley
In preparation for adding OMAP4-specific PRCM accessor/mutator functions, split the existing OMAP2/3 PRCM code into OMAP2/3-specific files. Most of what was in mach-omap2/{cm,prm}.{c,h} has now been moved into mach-omap2/{cm,prm}2xxx_3xxx.{c,h}, since it was OMAP2xxx/3xxx-specific. This process also requires the #includes in each of these files to be changed to reference the new file name. As part of doing so, add some comments into plat-omap/sram.c and plat-omap/mcbsp.c, which use "sideways includes", to indicate that these users of the PRM/CM includes should not be doing so.

2010-01-26OMAP2xxx clock: move the DPLL+CORE composite clock code into ↵Paul Walmsley
mach-omap2/clkt2xxx_dpllcore.c Move the DPLL+CORE composite clock functions from clock2xxx.c to mach-omap2/clkt2xxx_dpllcore.c. This is intended to make the clock code easier to understand, since all of the functions needed to manage the OMAP2 DPLL+CORE clock are now located in their own file, rather than being mixed with other, unrelated functions. Clock debugging is also now more finely-grained, since the DEBUG macro can now be defined for the DPLL+CORE clock alone. This should reduce unnecessary console noise when debugging. Also, if at some future point the mach-omap2/ directory is split into OMAP2/3/4 variants, this clkt file can be placed in the mach-omap2xxx/ directory, rather than shared with other chip types that don't use this clock type.
