2013-04-10cpufreq: OMAP: instantiate omap-cpufreq as a platform_driverNishanth Menon1-0/+9
As multi-platform build is being adopted by more and more ARM platforms, initcall function should be used very carefully. For example, when CONFIG_ARM_OMAP2PLUS_CPUFREQ is built in the kernel, omap_cpufreq_init() will be called on all the platforms to initialize omap-cpufreq driver. Further, on OMAP, we now use Soc generic cpufreq-cpu0 driver using device tree entries. To allow cpufreq-cpu0 and omap-cpufreq drivers to co-exist for OMAP in a single image, we need to ensure the following: 1. With device tree boot, we use cpufreq-cpu0 2. With non device tree boot, we use omap-cpufreq In the case of (1), we will have cpu OPPs and regulator registered as part of the device tree nodes, to ensure that omap-cpufreq and cpufreq-cpu0 don't conflict in managing the frequency of the same CPU, we should not permit omap-cpufreq to be probed. In the case of (2), we will not have the cpufreq-cpu0 device, hence only omap-cpufreq will be active. To eliminate this undesired these effects, we change omap-cpufreq driver to have it instantiated as a platform_driver and register "omap-cpufreq" device only when booted without device tree nodes on OMAP platforms. This allows the following: a) Will only run on platforms that create the platform_device "omap-cpufreq". b) Since the platform_device is registered only when device tree nodes are *not* populated, omap-cpufreq driver does not conflict with the usage of cpufreq-cpu0 driver which is used on OMAP platforms when device tree nodes are present. Inspired by commit 5553f9e26f6f49a93ba732fd222eac6973a4cf35 (cpufreq: instantiate cpufreq-cpu0 as a platform_driver) [robherring2@gmail.com: reported conflict of omap-cpufreq vs other driver in an non-device tree supported boot] Reported-by: Rob Herring <robherring2@gmail.com> Signed-off-by: Nishanth Menon <nm@ti.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Kevin Hilman <khilman@linaro.org> Signed-off-by: Rafael J.

Move omap_set_pwrdm_state() from the PM code to the powerdomain code, and refactor it to split it up into several functions. A subsequent patch will rename it to conform with the existing powerdomain function names. This version includes some additional documentation, based on a suggestion from Jean Pihet. It also modifies omap_set_pwrdm_state() to not bail out early unless both the powerdomain current power state and the next power state are equal. (Previously it would terminate early if the next power state was equal to the target power state, which was insufficiently rigorous.)

2012-10-08ARM: OMAP2+: PM: MPU DVFS: use generic CPU device for MPU-SSKevin Hilman1-1/+10
Currently, a dummy omap_device is created for the MPU sub-system so that a device node exists for MPU DVFS. Specifically, for the association of MPU OPPs to a device node, and so that a voltage regulator can be mapped to a device node. For drivers to get a handle to this device node, an OMAP-specific API has been used. However, the kernel already has device nodes for the CPU(s) in the system, so we can use those instead of an OMAP-specific dummy device and then drivers (like OMAP CPUfreq) can use generic APIs. To use the existing CPU device nodes, modify the OPP creation and regulator registration to use the CPU0 device node for registraion. NOTE: this patch always uses CPU0 as the device node. On all OMAPs today, MPU DVFS scales all CPUs together, so this will not be a problem, but this assumption will need to be changed if independently scalable CPUs are introduced.

2012-09-23ARM: OMAP2+: clockdomain/hwmod: add workaround for EMU clockdomain idle problemsPaul Walmsley1-1/+2
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.

2012-03-06ARM: OMAP2+: PM: fix section mismatch with omap2_init_processor_devices()Kevin Hilman1-1/+1
Fix the below warning by making omap2_init_processor_devices() __init. It is called by an __init function and calls only __init functions, so it should also be init. WARNING: arch/arm/mach-omap2/built-in.o(.text+0x183c): Section mismatch in reference from the function omap2_init_processor_devices() to the function .init.text:_init_omap_device() The function omap2_init_processor_devices() references the function __init _init_omap_device(). This is often because omap2_init_processor_devices lacks a __init annotation or the annotation of _init_omap_device is wrong.

2012-03-05ARM: OMAP2+: PM: share some suspend-related functions across OMAP2, 3, 4Paul Walmsley1-0/+64
The platform_suspend_ops can be shared across OMAP2, 3, and 4, along with all of the functions referenced in that structure. This patch shares them. It also removes the suspend_state file-scoped variable in the OMAP2 and 3 PM code; it does not appear to be actually needed by anything.

2012-03-05ARM: OMAP2+: PM: clean up omap_set_pwrdm_state()Paul Walmsley1-22/+17
Clean up a few different parts of omap_set_pwrdm_state(): - Remove a superfluous call to pwrdm_state_switch(). Not needed unless LOWPOWERSTATECHANGE is used, because the state switch code is called by either clkdm_sleep() or clkdm_allow_idle(). - Add code to wait for the power state transition in the OMAP4+ low power state change. This is speculative, so I would particularly appreciate feedback on this part. - Remove a superfluous call to pwrdm_read_pwrst(). - Update variable names to be more meaningful (hopefully) and precise. - Fix an error path bug that would not place the clockdomain back into hardware-supervised idle or sleep mode if the power state could not be programmed. The documentation for this function still needs major improvements; that's left for a later patch.

2012-02-24ARM: OMAP: convert omap_device_build() and callers to __initKevin Hilman1-1/+1
