2012-09-23ARM: OMAP4460/4470: PMU: Enable PMU for OMAP4460/70Jon Hunter3-10/+11
OMAP4460 and OMAP4470 devices have dedicated PMU interrupts and so add these interrupts to the MPU HWMOD so we can use these for PMU events on these devices. The PMU interrupts need to be the first interrupts in the array of interrupts as the ARM PMU driver assumes this. By using these dedicated interrupts we only need to enable the MPU and DEBUG sub-systems for PMU to work. This is different to OMAP4430 that did not have dedicated interrupts and required other power domains in addition to the DEBUG sub-system to be enabled so we could route the PMU events to the CTI interrupts. Hence, OMAP4460 and OMAP4470 devices can use the same list of HWMODs to create the PMU device that is using by OMAP3.

2012-09-23ARM: OMAP2+: PMU: Add runtime PM supportJon Hunter1-1/+7
The original implementation of this patch was done by Ming Lei for PMU on OMAP4 [1]. Since then the PM runtime calls have been moved into the ARM PMU code and this greatly simplifies the changes. The another differnce since the original version, is that it is no longer necessary to call pm_runtime_get/put during the PMU initialisation was we are no longer accessing the hardware at this stage. By adding runtime PM support, we can ensure that the appropriate power and clock domains are kept on while PMU is being used.

2012-09-23ARM: OMAP4430: PMU: prepare to create PMU device via HWMODMing Lei1-4/+12
For OMAP4430 PMU events are routed to the CPU via the cross trigger interface (CTI) because there are no dedicated interrupts. In order to route the PMU events via the CTI IRQs, the following modules must be enabled: l3_instr, l3_main_3, debugss Therefore, build the arm-pmu device via these three HWMODs. However, the CTI support for this platform still needs some work. Until that's finished, temporarily disable the PMU on OMAP4430.

2012-09-23ARM: OMAP2+: PMU: Convert OMAP2/3 devices to use HWMODJon Hunter5-29/+95
Convert OMAP2/3 devices to use HWMOD for creating a PMU device. To support PMU on OMAP2 devices we only need to use MPU sub-system and so we can simply use the MPU HWMOD to create the PMU device. To support PMU on OMAP3 devices, we need to use the MPU and DEBUG sub-systems and so use these HWMODs to create the PMU device for OMAP3. The MPU HWMOD for OMAP2/3 devices is currently missing the PMU interrupt and so add the PMU interrupt to the MPU HWMOD for these devices. This change also moves the PMU code out of the mach-omap2/devices.c files into its own pmu.c file as suggested by Kevin Hilman to de-clutter devices.c.

2012-09-23ARM: OMAP2+: clockdomain/hwmod: add workaround for EMU clockdomain idle problemsPaul Walmsley8-25/+88
The idle status of the IP blocks and clocks inside the EMU clockdomain isn't taken into account by the PRCM hardware when deciding whether the clockdomain is idle. Add a workaround flag in the clockdomain code, CLKDM_MISSING_IDLE_REPORTING, to deal with this problem, and add the code necessary to support it. If CLKDM_MISSING_IDLE_REPORTING is set on a clockdomain, the clockdomain will be forced active whenever an IP block inside that clockdomain is in use, even if the clockdomain supports hardware-supervised idle. When the kernel indicates that the last active IP block inside the clockdomain is no longer used, the clockdomain will be forced idle, or, if that mode is not supported in the hardware, it will be placed into hardware-supervised idle.

2012-09-23ARM: OMAP: Add a timer attribute for timers that can interrupt the DSPJon Hunter5-3/+39
Some instances of the DMTIMER peripheral on OMAP devices have the ability to interrupt the on-chip DSP in addition to the ARM CPU. Add a DMTIMER attribute to indicate which timers can interrupt the DSP. By using the omap_dm_timer_request_by_cap() API, driver will now be able to allocate a DMTIMER that can interrupt the DSP based upon this attribute and not require the driver to know which instance has this capability. DMTIMERs that have the ability to interrupt the DSP on OMAP devices are as follows ... - OMAP1 (OMAP5912/16xx/17xx) devices - All 8 DMTIMERs - OMAP2/3/4 devices - DMTIMERs 5-8 Please note that for OMAP3+, timer8 has the ability to interrupt the DSP and generate a PWM output.

Move the OMAP1-specific RNG device creation off to mach-omap1/devices.c, and create a omap_device-backed registration function for OMAP2+ devices in mach-omap2/devices.c. As a nice side-benefit, we can also get rid of arch/arm/plat-omap/devices.c, thanks to some recent changes from Tony. One change from the previous behavior is that the RNG devices are now registered unconditionally. This should allow the RNG drivers to be loaded as modules, even if the original kernel was not built that way. Signed-off-by: Paul Walmsley <paul@pwsan.com>

Some IP blocks might not be using/controlling more than one reset line, this check loosens the restriction to fully use hwmod framework for those drivers. E.g.: ipu has reset lines: mmu_cache, cpu0 and cpu1. - As of now cpu1 is not used and hence (with previous check) the IP block isn't fully enabled by hwmod code. - Usually ipu and dsp processors configure their mmu module first and then enable the processors, this involves: * Deasserting mmu reset line, and enabling the module. * Deasserting cpu0 reset line, and enabling the processor. The ones portrayed in this example are controlled through rproc_fw_boot in drivers/remoteproc/remoteproc_core.c While at it, prevent _omap4_module_disable if all the hardreset lines on an IP block are not under reset. This will allow the driver to: a. Deassert the reset line. b. Enable the hwmod through runtime PM default callbacks. c. Do its usecase. d. Disable hwmod through runtime PM. e. Assert the reset line.

2012-09-23ARM: OMAP4: hwmod data: add support for lostcontext_maskTero Kristo2-0/+10
Currently hwmod only provides the offset for the context lose register, and if we attempt to share the same register between two or more hwmods, the resulting context loss counts get wrong. Thus, we need a way to specify which bits are used for the context loss information for each. This is accomplished by adding a new field to the omap4 prcm struct, 'lostcontext_mask', which specifies a bit-mask to use for filtering the register. Mark the affected hwmods appropriately. 'l4_abe' hwmod uses the LOSTMEM_AESSMEM bit of RM_ABE_AESS_CONTEXT register, as l4_abe doesn't have its own dedicated register for this purpose. This register is shared with 'aess' hwmod, thus both hwmods must also specify which bits of the register are used for them. This patch only adds the hwmod data, but a future patch should add code support such that only the specified bits are read and cleared by the context lose counter update code. If a hwmod doesn't specify 'lostcontext_mask' (default behavior), the whole contents of the context register should be used without any filtering.

On OMAP4, there is no support to read previous logic state or previous memory state achieved when a power domain transitions to RET. Instead there are module level context registers. In order to support the powerdomain level logic/mem_off_counters on OMAP4, instead use the previous power state achieved (RET) and the *programmed* logic/mem RET state to derive if a powerdomain lost logic or did not. If the powerdomain is programmed to enter RET state and lose logic in RET state, knowing that the powerdomain entered RET is good enough to derive that the logic was lost as well, in such cases.

2012-09-23ARM: OMAP2+: hwmod code: convert missing clockdomain warnings to debug messagesPaul Walmsley1-2/+4
The decision was made a few months ago to allow struct omap_hwmod records and struct clk records to omit clockdomain information if the clockdomain is not software-controllable. See for example commit 868c157df9721675c19729eed2c96bac6c3f1d01 ("ARM: OMAP2+: hwmod: remove prm_clkdm, cm_clkdm; allow hwmods to have no clockdomain"). So convert an existing pr_warning() to a pr_debug() (regarding missing clockdomains in clocks), and add a pr_debug() for missing hwmod clockdomains. It's still useful to enable these messages for debugging, since missing clockdomains can cause hard-to-debug problems with power management; see for example commit 6c4a057bffe9823221eab547e11fac181dc18a2b ("ARM: OMAP4: clock data: Force a DPLL clkdm/pwrdm ON before a relock").

2012-09-23ARM: OMAP2+: omap_device: expose hwmod assert/deassert to omap devicesOmar Ramirez Luna2-0/+59
This API is meant to be an interface to hwmod assert/deassert function, omap devices can call them through their platform data to control their reset lines, they are expected to know the name of the reset line they are trying to control.

2012-09-23ARM: OMAP: hwmod code: remove unused hwmod function prototypesIgor Grinberg1-7/+0
Several hwmod function prototypes appear to not have an implementation because the corresponding functions were removed or renamed. Those prototypes are unneeded anymore - remove them.

These fixes are needed to fix non-omap build breakage for twl-core driver and to fix omap1_defconfig compile when led driver changes and omap sparse IRQ changes are merged together. Also fix warnings for omaps not using pinctrl framework yet.

smatch and string-wrapping cleanups for the OMAP subarch code. These changes fix some of the more meaningful warnings that smatch returns for the OMAP subarch code, and unwraps strings that are wrapped at the 80-column boundary, to conform with the current practice. Basic build, boot, and PM logs are available here: http://www.pwsan.com/omap/testlogs/warnings_a_cleanup_3.7/20120912025927/
