2017-10-12iommu/exynos: Remove initconst attribute to avoid potential kernel oopsMarek Szyprowski1-1/+1
Exynos SYSMMU registers standard platform device with sysmmu_of_match table, what means that this table is accessed every time a new platform device is registered in a system. This might happen also after the boot, so the table must not be attributed as initconst to avoid potential kernel oops caused by access to freed memory.

Commit 09515ef5ddad ("of/acpi: Configure dma operations at probe time for platform/amba/pci bus devices") postponed the moment of attaching IOMMU controller to its device, so there is no need to register IOMMU controllers very early, before all other devices in the system.

2017-03-22iommu/exynos: Workaround FLPD cache flush issues for SYSMMU v5Marek Szyprowski1-1/+4
For some unknown reasons, in some cases, FLPD cache invalidation doesn't work properly with SYSMMU v5 controllers found in Exynos5433 SoCs. This can be observed by a firmware crash during initialization phase of MFC video decoder available in the mentioned SoCs when IOMMU support is enabled. To workaround this issue perform a full TLB/FLPD invalidation in case of replacing any first level page descriptors in case of SYSMMU v5.

2017-01-26iommu: Drop the of_iommu_{set/get}_ops() interfaceLorenzo Pieralisi1-1/+1
With the introduction of the new iommu_{register/get}_instance() interface in commit e4f10ffe4c9b ("iommu: Make of_iommu_set/get_ops() DT agnostic") (based on struct fwnode_handle as look-up token, so firmware agnostic) to register IOMMU instances with the core IOMMU layer there is no reason to keep the old OF based interface around any longer. Convert all the IOMMU drivers (and OF IOMMU core code) that rely on the of_iommu_{set/get}_ops() to the new kernel interface to register/retrieve IOMMU instances and remove the of_iommu_{set/get}_ops() remaining glue code in order to complete the interface rework.

2017-01-10iommu/exynos: Ensure that SYSMMU is added only once to its master deviceMarek Szyprowski1-1/+5
This patch prepares Exynos IOMMU driver for deferred probing support. Once it gets added, of_xlate() callback might be called more than once for the same SYSMMU controller and master device (for example it happens when masters device driver fails with EPROBE_DEFER). This patch adds a check, which ensures that SYSMMU controller is added to its master device (owner) only once.

2016-11-14iommu/exynos: Use device dependency links to control runtime pmMarek Szyprowski1-10/+10
This patch uses recently introduced device dependency links to track the runtime pm state of the master's device. The goal is to let SYSMMU controller device's runtime PM to follow the runtime PM state of the respective master's device. This way each SYSMMU controller is active only when its master's device is active and can properly restore or save its state instead on runtime PM transition of master's device. This approach replaces old behavior, when SYSMMU controller was set to runtime active once after attaching to the master device. In the new approach SYSMMU controllers no longer prevents respective power domains to be turned off when master's device is not being used. This patch reduces total power consumption of idle system, because most power domains can be finally turned off. For example, on Exynos 4412 based Odroid U3 this patch reduces power consuption from 136mA to 130mA at 5V (by 4.4%). The dependency links also enforce proper order of suspending/restoring devices during system sleep transition, so there is no more need to use LATE_SYSTEM_SLEEP_PM_OPS-based workaround for ensuring that SYSMMUs are suspended after their master devices.

2016-11-14iommu/exynos: Add runtime pm supportMarek Szyprowski1-9/+36
This patch adds runtime pm implementation, which is based on previous suspend/resume code. SYSMMU controller is now being enabled/disabled mainly from the runtime pm callbacks. System sleep callbacks relies on generic pm_runtime_force_suspend/pm_runtime_force_resume helpers. To ensure internal state consistency, additional lock for runtime pm transitions was introduced.

Now page access bits are set according to the protection bits provided in iommu_map(), so Exynos SYSMMU is able to detect incorrect access to mapped pages. Exynos SYSMMU earlier than v5 doesn't support write-only mappings, so pages with such protection bits are mapped as read/write.
