2013-04-23ARM: OMAP2+: add dependencies on ARCH_MULTI_V6/V7Arnd Bergmann1-0/+5
CONFIG_ARCH_OMAP2PLUS depends on (ARCH_MULTI_V6 || ARCH_MULTI_V7) as of a0694861 "ARM: OMAP2+: Enable ARCH_MULTIPLATFORM support", but the individual OMAP2/3/4/5 and AM33XX platforms can all be selected independent of what we are building for, which is a bug and prevents us from easily building e.g. an ARMv7-only defconfig. This makes ARCH_OMAP2 depend on ARCH_MULTI_V6 and the others depend on ARCH_MULTI_V7, to ensure we really only build the platforms for the CPUs we have enabled in the global multiplatform configuration step.

2013-04-22ARM: OMAP3: remove cpuidle_wrap_enterDaniel Lezcano1-21/+9
In a previous commit the en_core_tk_irqen flag has been added but we missed the cpuidle_wrap_enter which was doing the job to measure the time for the 'omap3_enter_idle' function. Actually, I don't see any reason to use this wrapper in the code. In the better case, the time computation is not correctly done because of the different operations done in omap3_enter_idle_bm which were not taken into account before the en_core_tk_irqen flag was set. As the time is reflected for the state overridden by the omap3_enter_idle_bm, using the wrapper is pointless now, so removing it.

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.

2013-04-09ARM: Push selects for TWD/SCU into machine entriesStephen Boyd1-0/+2
The TWD and SCU configs are selected by default as long as MSM_SCORPIONMP is false and/or MCT is false. Implementing the logic this way certainly saves lines in the Kconfig but it precludes those machines which select MSM_SCORPIONMP or MCT from participating in the single zImage effort because when those machines are combined with other SMP capable machines the TWD and SCU are no longer selected by default. Push the select out to the machine entries so that we can compile these machines together and still select the appropriate configs.

2013-04-09ARM: OMAP4+: CPUidle: Deprecate use of omap4_mpuss_read_prev_context_state()Santosh Shilimkar3-20/+2
Current OMAP4 CPUIdle driver is using omap4_mpuss_read_prev_context_state() to check whether the MPU cluster lost context or not before calling cpu_cluster_pm_exit(). This was initially done an optimization for corner cases, where if the cluster low power entry fails for some reason, the cluster context restore gets skipped. However, since reading the previous context is expensive (involving slow accesses to the PRCM), it's better to avoid it and simply check the target cluster state instead. Moving forward, OMAP CPUidle drivers needs to be moved to drivers/idle/* once the PRM/CM code gets moved to drivers. This patch also reduces one dependency with platform code for idle driver movement.

2013-04-08ARM: OMAP2+: Export SoC information to userspaceRuslan Bilovol4-0/+75
In some situations it is useful for userspace to know some SoC-specific information. For example, this may be used for deciding what kernel module to use or how to better configure some settings etc. This patch exports OMAP SoC information to userspace using existing in Linux kernel SoC infrastructure. This information can be read under /sys/devices/socX directory Signed-off-by: Ruslan Bilovol <ruslan.bilovol@ti.com> [tony@atomide.com: updated for multiplatform changes] Signed-off-by: Tony Lindgren <tony@atomide.com>

Update the DMTIMER compatibility property to reflect the register level compatibilty between devices and update the various OMAP/AM timer bindings with the appropriate compatibility string. By doing this we can add platform specific data applicable to specific timer versions to the driver. For example, errata flags can be populated for the timer versions that are impacted.

2013-04-09ARM: OMAP2+: hwmod: Don't call _init_mpu_rt_base if no syscSantosh Shilimkar1-1/+2
OMAP hwmod layer does the reset of the IPs in early code so that we have SOC in sane state. To do the soft-reset, it needs to ioremap() the IP address space to be able to write to sysconfig registers. But there are few hwmod which doesn't have sysconfig registers and hence no need to ioremap() them in early init code. Prevent calling the _init_mpu_rt_base() conditional based on sysc availability.

If device-tree is present, then do not create the PMU device from within the OMAP specific PMU code. This is required to allow device-tree to create the PMU device from the PMU device-tree node. PMU is not currently supported for OMAP4430 (due to a dependency on having a cross-trigger interface driver) and so ensure that this indicated on boot with or without device-tree.
