We want to remove plat/cpu.h. To do this, let's first split it to private soc.h to mach-omap1 and mach-omap2. We have to keep plat/cpu.h around until the remaining drivers are fixed, so let's include the local soc.h in plat/cpu.h and for drivers still including plat/cpu.h. Once the drivers are fixed not to include plat/cpu.h, we can remove the file. This is needed for the ARM common zImage support.

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. This patch is an equal collaboration with Jon Hunter <jon-hunter@ti.com>.

Kevin discovered that commit c8d82ff6 ("ARM: OMAP2/3: hwmod data: Add 32k-sync timer data to hwmod database") broke CORE idle on OMAP3. This prevents device low power states. The root cause is that the 32K sync timer IP block does not support smart-idle mode[1], and so the hwmod code keeps the IP block in no-idle mode while it is active. This in turn prevents the WKUP clockdomain from transitioning to idle. There is a hardcoded sleep dependency that prevents the CORE_L3 and CORE_CM clockdomains from transitioning to idle when the WKUP clockdomain is active[2], so the chip cannot enter any device low power states. It turns out that there is no need to take the 32k sync timer out of idle. The IP block itself probably does not have any native idle handling at all, due to its simplicity. Furthermore, the PRCM will never request target idle for this IP block while the kernel is running, due to the sleep dependency that prevents the WKUP clockdomain from idling while the CORE_L3 clockdomain is active. So we can safely leave the 32k sync timer in target-force-idle mode, even while we continue to access it. This workaround is implemented by defining a new clockdomain flag, CLKDM_ACTIVE_WITH_MPU, that indicates that the clockdomain is guaranteed to be active whenever the MPU is inactive. If an IP block's main functional clock exists inside this clockdomain, and the IP block does not support smart-idle modes, then the hwmod code will place the IP block into target force-idle mode even when enabled. The WKUP clockdomains on OMAP3/4 are marked with this flag. (On OMAP2xxx, no OCP header existed on the 32k sync timer.) Other clockdomains also should be marked with this flag, but those changes are deferred until a later merge window, to create a minimal fix. Another theoretically clean fix for this problem would be to implement PM runtime-based control for 32k sync timer accesses. These PM runtime calls would need to located in a custom clocksource, since the 32k sync timer is currently used as an MMIO clocksource. But in practice, there would be little benefit to doing so; and there would be some cost, due to the addition of unnecessary lines of code and the additional CPU overhead of the PM runtime and hwmod code - unnecessary in this case. Another possible fix would have been to modify the pm34xx.c code to force the IP block idle before entering WFI. But this would not have been an acceptable approach: we are trying to remove this type of centralized IP block idle control from the PM code.

In preparation for OMAP_CHIP() removal, split clkdm_init() into four functions. This allows some of them to be called multiple times: for example, clkdm_register_clkdms() can be called once to register clockdomains that are common to a group of SoCs, and once to register clockdomains that are specific to a single SoC. The appropriate order to call these functions - which is enforced by the code - is: 1. clkdm_register_platform_funcs() 2. clkdm_register_clkdms() (can be called multiple times) 3. clkdm_register_autodeps() (optional; deprecated) 4. clkdm_complete_init() Convert the OMAP2, 3, and 4 clockdomain init code to use these new functions.

Add a new function, clkdm_in_hwsup(), that returns true if a clockdomain is configured for hardware-supervised idle. It does not actually read the hardware; rather, it checks an internal flag in the struct clockdomain, which is changed when the clockdomain is switched in and out of hardware-supervised idle. This should be safe, since all changes to the idle mode should pass through the clockdomain code.

Add a new clockdomain flag, CLKDM_NO_AUTODEPS, which, when marked on a clockdomain, will prevent "autodeps" from being associated with the clockdomain. ("Autodeps" are sleep dependencies and wakeup dependencies from/to processor modules that are automatically added to a clockdomain when it is in hardware-supervised idle mode. They are deprecated -- a relic from the old CDP trees -- but are still in use for OMAP3.) Also, prevent the hwmod code from adding or removing initiator dependencies for clockdomains with this flag set. This patch should allow others to test which clockdomains actually still need autodeps. Thanks to Kevin Hilman <khilman@ti.com> for noting that the original version should also modify the hwmod code.

Add usecounting for wakeup and sleep dependencies. In the current situation, if several functions add dependencies on the same clockdomains, when the first dependency removal function is called, the dependency will be incorrectly removed from the hardware. Add clkdm_clear_all_wkdeps() and clkdm_clear_all_sleepdeps(), which provide a fast and usecounting-consistent way to clear all hardware clockdomain dependencies, since accesses to these registers can be quite slow. pm{2,3}4xx.c has been updated to use these new functions. The original version of this patch did not touch these files, which previously wrote directly to the wkdep registers, and thus confused the usecounting code. This problem was found by Kevin Hilman <khilman@deeprootsystems.com>. N.B.: This patch introduces one significant functional difference over the previous pm34xx.c code: sleepdeps are now cleared during clockdomain initialization, whereas previously they were left untouched. This has been tested by Kevin and confirmed to work. The original version of this patch also did not take into consideration that some clockdomains do not have sleep or wakeup dependency sources, which caused NULL pointer dereferences.

This patch creates an interface to the clockdomain registers in the PRM/CM modules on OMAP2/3. This interface is intended to be used by PM code, e.g., pm.c; not by device drivers directly. The patch also adds clockdomain usecount tracking. This is intended to be called whenever the first clock in a clockdomain is enabled, or when the last enabled clock in a clockdomain is disabled. If the clockdomain is in software-supervised mode, the code will force-wakeup or force-sleep the clockdomain. If the clockdomain is in hardware-supervised mode, the first clock enable will add sleep and wakeup dependencies on a user-selectable set of parent domains (usually MPU & IVA2), and the disable will remove them. Each clockdomain will be defined in later patches as static structures. The clockdomain structures are linked into a list at boot by clkdm_register(), similar to the OMAP clock code. The patch adds a Kconfig option, CONFIG_OMAP_DEBUG_CLOCKDOMAIN, which when enabled will emit verbose debug messages via pr_debug().
