* ARM: OMAP2+: powerdomain: fix whitespace, improve flag commentsPaul Walmsley2013-01-294-40/+42
| | | | | | | | | | Fix some whitespace problems introduced by commit da03ce65b5431245b9cd20db3edaaa6b9f5c8dc1 ("OMAP3: powerdomain data: add voltage domains"). Also, improve the documentation for the struct powerdomain.flags field. Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: Kevin Hilman <khilman@deeprootsystems.com>
* ARM: OMAP2+: clockdomain: convert existing atomic usecounts into ↵Paul Walmsley2013-01-297-30/+92
| | | | | | | | | | | | spinlock-protected shorts/ints The atomic usecounts seem to be confusing, and are no longer needed since the operations that they are attached to really should take place under lock. Replace the atomic counters with simple integers, protected by the enclosing powerdomain spinlock. Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: Kevin Hilman <khilman@deeprootsystems.com>
* ARM: OMAP2+: clockdomain: work on wkdep/sleepdep functionsPaul Walmsley2013-01-293-167/+240
| | | | | | | | | | | Split the clkdm_(add|del)_(wk|sleep)dep() functions into lockless and locking versions -- this will be needed in a subsequent patch. Also, while here, remove the leading underscore, since these are not currently static functions. And for functions that have kerneldoc-style comment blocks, but which are missing the initial '/**' tag, fix the tag to indicate that they are kerneldoc. Signed-off-by: Paul Walmsley <paul@pwsan.com>
* ARM: OMAP2xxx: CM: remove autodep handlingPaul Walmsley2013-01-291-29/+4
| | | | | | | | | There's no need to preserve the autodep handling code in mach-omap2/cm2xxx.c, since no autodeps are defined for these chips. Hopefully they'll never be needed, but if in some future case they are, this code can be added back in. Signed-off-by: Paul Walmsley <paul@pwsan.com>

| | | | | | | | | | Add a per-powerdomain spinlock. Use that instead of the clockdomain spinlock. Add pwrdm_lock()/pwrdm_unlock() functions to allow other code to acquire or release the powerdomain spinlock without reaching directly into the struct powerdomain.

* ARM: OMAP2+: PM/powerdomain: move omap_set_pwrdm_state() to powerdomain codePaul Walmsley2013-01-294-92/+144
| | | | | | | | | | | | | | | | | | 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.)

* ARM: OMAP2xxx: PM: clean up some crufty powerstate programming codePaul Walmsley2013-01-291-20/+10
| | | | | | | | | | | | | | | | | | Don't attempt to put clockdomains to sleep; this should be handled by the clock framework. It should be enough to program the next-power-state, and then let the code in omap_pm_clkdms_setup() deal with the rest. Start out by programming the MPU and CORE powerdomains to stay ON. Then control the MPU and CORE powerdomain states directly in omap2_enter_full_retention() and omap2_enter_mpu_retention(). Not the most optimal way to do it, but certainly is the most conservative until OMAP2xxx PM is working again. Get rid of the open-coded PM_PWSTCTRL_MPU writes in omap2_enter_mpu_retention(); use the powerdomain code instead.

* ARM: OMAP2+: clockdomain: add pwrdm_state_switch() call to clkdm_sleep()Paul Walmsley2013-01-291-0/+1
| | | | | | | | | | | | | | | In clkdm_sleep(), the powerdomain should be eligible to switch power states right after the call to the low-level clockdomain sleep function. We should have been tracking that with the pwrdm_state_switch() code, but we weren't, for whatever reason. Fix that. This resolves the "pwrdm state mismatch(cam_pwrdm) 3 != 0" that appears during the OMAP4460 Pandaboard-ES PM test, e.g. here: http://www.pwsan.com/omap/testlogs/test_v3.8-rc5/20130126003323/pm/4460pandaes/4460pandaes_log.txt Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: Tero Kristo <t-kristo@ti.com>

* ARM: OMAP3xxx: CPUIdle: optimize __omap3_enter_idle()Paul Walmsley2013-01-291-13/+22
| | | | | | | | | | | | | | | | | | | | | | | Avoid programming the MPU and CORE powerdomain next-power-state registers if those powerdomains will never enter low-power states (e.g., the state that people refer to as "C1"). To avoid making assumptions about CPUIdle states based on their order in the list, use a flag to mark CPUIdle states that don't enter powerdomain low-power states. Avoid a previous-power-state register read on the MPU powerdomain unless we know that the MPU was supposed to go OFF during the last state transition. Previous-power-state register reads can be very expensive, so it's worth avoiding these when possible. Since the CORE_L3 clockdomain can't go inactive unless the MPU is active, there's little point blocking autoidle on the CORE_L3 clockdomain in "C1" state, since we've programmed the MPU clockdomain to stay active. Remove the unnecessary code. Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: Kevin Hilman <khilman@deeprootsystems.com>

| | * ARM: OMAP2/3: PRM: fix bogus OMAP2xxx powerstate return valuesPaul Walmsley2013-01-023-28/+110
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On OMAP2xxx chips, the register bitfields for the PM_PWSTCTRL_*.POWERSTATE and PM_PWSTST_*.LASTSTATEENTERED are different than those used on OMAP3/4. The order is reversed. So, for example, on OMAP2xxx, 0x0 indicates 'ON'; but on OMAP3/4, 0x0 indicates 'OFF'. Similarly, on OMAP2xxx, 0x3 indicates 'OFF', but on OMAP3/4, 0x3 indicates 'ON'. To fix this, we treat the OMAP3/4 values as the powerdomain API values, and create new low-level powerdomain functions for the OMAP2xxx chips which translate between the OMAP2xxx values and the OMAP3/4 values. Without this patch, the conversion of the OMAP2xxx PM code to the functional powerstate code results in a non-booting kernel. Signed-off-by: Paul Walmsley <paul@pwsan.com>

Thanks everybody for help with fixing the drivers. Note that we can now also remove the unused plat/cpu.h from smartreflex.c and isp.c as they will cause compile errors with ARCH_MULTIPLATFORM enabled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Looks like we missed plat-omap/fb.c for cpu_is_omap usage mach-omap2. This is the last user of cpu_is_omap, so let's quickly fix it up so we can finally remove plat/cpu.h for omap2lus. We want to limit cpu_is_omap macro usage to mach-omap2 only so we can make plat/cpu.h private. After this we can finally drop plat/cpu.h for omap2+.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 787314c35fbb ("Merge tag 'iommu-updates-v3.8' of git://git./linux/kernel/git/joro/iommu") did not account for the changed header location. The headers were made local to mach-omap2 as they are specific to omap2+ only, and we wanted to get most of the #include <plat/*.h> headers fixed up anyways for the ARM multiplatform support. We attempted to avoid this kind of merge conflict early on by setting up a minimal git branch shared by the arm-soc tree and the iommu tree, but looks like we still hit a merge issue there as the branches got merged as various topic branches.

The most important one is probably, that dma-debug now warns if a dma-handle is not checked with dma_mapping_error by the device driver. This requires minor changes to some architectures which make use of dma-debug. Most of these changes have the respective Acks by the Arch-Maintainers. Besides that there are updates to the AMD IOMMU driver for refactor the IOMMU-Groups support and to make sure it does not trigger a hardware erratum. The OMAP changes (for which I pulled in a branch from Tony Lindgren's tree) have a conflict in linux-next with the arm-soc tree. The conflict is in the file arch/arm/mach-omap2/clock44xx_data.c which is deleted in the arm-soc tree. It is safe to delete the file too so solve the conflict. Similar changes are done in the arm-soc tree in the common clock framework migration. A missing hunk from the patch in the IOMMU tree will be submitted as a seperate patch when the merge-window is closed." * tag 'iommu-updates-v3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (29 commits) ARM: dma-mapping: support debug_dma_mapping_error ARM: OMAP4: hwmod data: ipu and dsp to use parent clocks instead of leaf clocks iommu/omap: Adapt to runtime pm iommu/omap: Migrate to hwmod framework iommu/omap: Keep mmu enabled when requested iommu/omap: Remove redundant clock handling on ISR iommu/amd: Remove obsolete comment iommu/amd: Don't use 512GB pages iommu/tegra: smmu: Move bus_set_iommu after probe for multi arch iommu/tegra: gart: Move bus_set_iommu after probe for multi arch iommu/tegra: smmu: Remove unnecessary PTC/TLB flush all tile: dma_debug: add debug_dma_mapping_error support sh: dma_debug: add debug_dma_mapping_error support powerpc: dma_debug: add debug_dma_mapping_error support mips: dma_debug: add debug_dma_mapping_error support microblaze: dma-mapping: support debug_dma_mapping_error ia64: dma_debug: add debug_dma_mapping_error support c6x: dma_debug: add debug_dma_mapping_error support ARM64: dma_debug: add debug_dma_mapping_error support intel-iommu: Prevent devices with RMRRs from being placed into SI Domain ...
| * | ARM: OMAP4: hwmod data: ipu and dsp to use parent clocks instead of leaf clocksOmar Ramirez Luna2012-12-032-24/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This prevents hwmod _enable_clocks...omap2_dflt_clk_enable path from enabling modulemode inside CLKCTRL using its clk->enable_reg field. Instead is left to _omap4_enable_module though soc_ops, as the one in charge of this setting. According to comments received[1] for related patches the idea is to get rid of leaf clocks in future. So remove these two while at it.

Due to reset sequence, pm_runtime_[get|put]_sync must be used, to avoid possible operations with the module under reset. Because of this and given that the driver uses spin_locks to protect their critical sections, we must use pm_runtime_irq_safe in order for the runtime ops to be happy, otherwise might_sleep_if checks in runtime framework will complain. The remaining pm_runtime out of iommu_enable and iommu_disable corresponds to paths that can be accessed through debugfs, some of them doesn't work if the module is not enabled first, but in future if the mmu is idled withouth freeing, these are needed to debug.
