2015-03-31ARM: OMAP2+: clock: add low-level support for regmapTero Kristo1-1/+1
Some of the TI clock providers will be converted to use syscon, thus low-level regmap support is needed for the clock drivers also. This patch adds this support, which can be enabled for individual drivers in later patches. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-03-31ARM: OMAP2+: CM: move SoC specific init calls within a generic APITero Kristo1-10/+54
This gets rid of need for some exported driver APIs, and simplifies the initialization of the CM driver. Done in preparation to make CM a separate driver. The init data is now also passed to the SoC specific implementations, allowing future expansion to add feature flags etc. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-03-27ARM: OMAP2+: CM: determine CM base address from device treeTero Kristo1-6/+67
There is no need to provide the CM base address through a low-level API from the low-level IO init, as this information is available through DT. Re-routed the parsing function to be called from the CM drivers also to simplify the implementation under io.c. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-03-27ARM: OMAP2+: PRCM: split PRCM module init to their own driver filesTero Kristo1-0/+51
Splits the clock related provider module inits under their own driver files. Previously this was done for all modules under the common PRM driver. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2014-10-27ARM: OMAP2+: CM: add common APIs for cm_module_enable/disableTero Kristo1-0/+45
Adds a generic CM driver API for enabling/disabling modules. The SoC specific implementations are registered through cm_ll_data. Signed-off-by: Tero Kristo <t-kristo@ti.com> Tested-by: Nishanth Menon <nm@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2014-10-27ARM: OMAP4+/AM33xx: CM: add common API for cm_wait_module_idleTero Kristo1-0/+26
Adds a generic CM driver API for waiting module to enter idle / standby. The SoC specific implementations are registered through cm_ll_data.

2014-10-27ARM: OMAP2+: CM: add common API for cm_wait_module_readyTero Kristo1-4/+7
This patch consolidates the parameters provided for the SoC specific cm_*_wait_module_ready calls, adds the missing cm_ll_data function pointers and uses the now generic call from the mach-omap2 board code. SoC specific *_wait_module_ready calls are also made static so they can only be accessed through the generic CM driver API only.

2014-05-15ARM: OMAP2+: PRCM: cleanup some header includesTero Kristo1-1/+1
Some of the includes are totally unnecessary, remove some others in preparation to make the PRCM its own driver. Signed-off-by: Tero Kristo <t-kristo@ti.com> [paul@pwsan.com: updated to apply; fixed build error on OMAP2xxx-only configs] Signed-off-by: Paul Walmsley <paul@pwsan.com>

2012-11-08ARM: OMAP2+: PRCM: split and relocate the PRM/CM globals setupPaul Walmsley1-1/+21
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. At this point arch/arm/plat-omap/include/plat/prcm.h is empty; a subsequent patch will remove it, and remove the #include from all the files that #include it.

2012-11-08ARM: OMAP2+: CM/clock: convert _omap2_module_wait_ready() to use ↵Paul Walmsley1-0/+48
SoC-independent CM functions Convert the OMAP clock code's _omap2_module_wait_ready() to use SoC-independent CM functions that are provided by the CM code, rather than using a deprecated function from mach-omap2/prcm.c. This facilitates the future conversion of the CM code to a driver, and also removes a mach-omap2/prcm.c user. mach-omap2/prcm.c will be removed by a subsequent patch. Some modules have IDLEST registers that aren't in the CM module, such as the AM3517 IDLEST bits. So we also need a fallback function for these non-CM odd cases. Create a temporary one in mach-omap2/clock.c, intended to exist until the SCM drivers are ready. Signed-off-by: Paul Walmsley <paul@pwsan.com> Tested-by: Vaibhav Hiremath <hvaibhav@ti.com>
2012-10-21ARM: OMAP2+: CM: prepare for use of cm_ll_data function pointersPaul Walmsley1-0/+71
There are several CM operations which behave similarly across OMAP2+ SoCs, but which have slight differences in their underlying implementations. This patch creates the support code for this function pointer registration process. No function pointers are included yet, but a subsequent patch will create these for the module IDLEST registers. This patch allows other code to use CM-provided data and operations without needing to know which SoC is currently in use. A further description of the concept is provided in the patch entitled "ARM: OMAP2+: PRM: prepare for use of prm_ll_data function pointers". Signed-off-by: Paul Walmsley <paul@pwsan.com>
