* ARM: OMAP4+: PRM: get rid of cpu_is_omap44xx calls from interrupt initTero Kristo2015-03-311-2/+4
| | | | | | | | | | The compatible DT node is now passed with the prm init, so there is no need to do node matching here again. Added a new flag to the init data also, to detect default IRQ support for OMAP4. Also, any booting omap4 DT setup always has a PRM node, so there is no need to check against the special case where it would be missing. Signed-off-by: Tero Kristo <t-kristo@ti.com>
* ARM: OMAP2+: PRM: move SoC specific init calls within a generic APITero Kristo2015-03-311-0/+1
| | | | | | | | | This gets rid of need for some exported driver APIs, and simplifies the initialization of the PRM driver. Done in preparation to make PRM 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>
* ARM: OMAP2+: control: determine control module base address from DTTero Kristo2015-03-271-1/+0
| | | | | | | | | | There is no need to provide the control module base address through a low-level API from the low-level IO init, as this information is available through DT. This patch adds a new API to initialize the control module though, but mostly makes the old API obsolete. The old API can be completely removed once OMAP3 is made DT only.

* ARM: OMAP3: PRM: add support for legacy iomapping initTero Kristo2015-01-301-0/+1
| | | | | | | | | | | | As the legacy clock data is being moved under clock driver, the clock data will be using the same low level infrastructure for register accesses. This requires the clk_memmaps to be initialized properly. This patch adds a support hook to the PRM driver to initialize the mappings.

* ARM: OMAP2+: hwmod: Add support for per hwmod/module context lost countRajendra Nayak2012-11-211-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OMAP4 has module specific context lost registers which makes it now possible to have module level context loss count, instead of relying on the powerdomain level context count.

Update the module specific context_lost_counter and clear the hardware bits just after enabling the module. omap_hwmod_get_context_loss_count() now returns the hwmod context loss count them on platforms where they exist (OMAP4), else fall back on the pwrdm level counters for older platforms.

* ARM: OMAP2+: PRM: create PRM reset source API for the watchdog timer driverPaul Walmsley2012-10-211-1/+43
| | | | | | | | | | | | | | | | | | The OMAP watchdog timer driver needs to determine what caused the SoC to reset for its GETBOOTSTATUS ioctl. So, define a set of standard reset sources across OMAP SoCs. For OMAP2xxx, 3xxx, and 4xxx SoCs, define mappings from the SoC-specific reset source register bits to the standardized reset source IDs. Create SoC-specific PRM functions that read the appropriate per-SoC register and use the mapping to return the standardized reset bits. Register the SoC-specific PRM functions with the common PRM code via prm_register(). Create a function in the common PRM code, prm_read_reset_sources(), that calls the SoC-specific function, registered during boot. This patch does not yet handle some SoCs, such as AM33xx. Those SoCs were not handled by the code this will replace. Signed-off-by: Paul Walmsley <paul@pwsan.com>
* ARM: OMAP2+: PRM: prepare for use of prm_ll_data function pointersPaul Walmsley2012-10-211-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | There are several PRM operations which behave similarly across OMAP2+ SoCs, but which have slight differences in their underlying implementations. For example, to fetch the SoC's last reset sources, different registers are read across OMAP2xxx, 3xxx, and 44xx, and different bits are used on each SoC. But the information returned is so similar that a single, common interface for drivers is useful. This patch creates the support code for this function pointer registration process. No function pointers are included yet, but a subsequent patch will create one for the reset source API. To illustrate the end goal with the above reset source example, each per-SoC driver will use its own low-level implementation function -- e.g., prm2xxx.c would contain omap2xxx_prm_read_reset_sources(). This function would read the appropriate register and remap the register bits to a standard set of reset source bits. When the prm2xxx.c driver is loaded, it would register this function with the common PRM driver, prm.c. prm.c would then export a common function, omap_prm_read_reset_sources(). Calling it would call through to the function pointer for the currently-registered SoC PRM driver. This will allow other drivers to use PRM-provided data and operations without needing to know which SoC is currently in use. Signed-off-by: Paul Walmsley <paul@pwsan.com>
* OMAP2/3: PRCM: split OMAP2/3-specific PRCM code into OMAP2/3-specific filesPaul Walmsley2010-12-211-348/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* OMAP4: PRCM: reorganize existing OMAP4 PRCM header filesPaul Walmsley2010-12-211-17/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | Split the existing cm44xx.h file into cm1_44xx.h and cm2_44xx.h files so they match their underlying OMAP hardware modules. Add clockdomain offset information. Add header files for the MPU local PRCM, prcm_mpu44xx.h, and for the SCRM, scrm44xx.h. SCRM register offsets still need to be added; TI should do this. Move the "_MOD" macros out of the prcm-common.h header file, into the header file of the hardware module that they belong to. For example, OMAP4430_PRM_*_MOD macros have been moved into the prm44xx.h header. Adjust #includes of all files that used the old PRCM header file names to point to the new filenames. The autogeneration scripts have been updated accordingly.
