2012-11-20ARM: OMAP2+: Move iommu/iovmm headers to platform_dataTony Lindgren1-49/+0
Move iommu/iovmm headers from plat/ to platform_data/ as part of the single zImage work. Partially based on an earlier version by Ido Yariv <ido@wizery.com>.

2012-11-20ARM: OMAP2+: Move iommu2 to drivers/iommu/omap-iommu2.cTony Lindgren1-258/+14
This file should not be in arch/arm. Move it to drivers/iommu to allow making most of the header local to drivers/iommu. This is needed as we are removing plat and mach includes from drivers for ARM common zImage support.

2012-11-20ARM: OMAP2+: Move plat/iovmm.h to include/linux/omap-iommu.hTony Lindgren1-8/+2
Looks like the iommu framework does not have generic functions exported for all the needs yet. The hardware specific functions are defined in files like intel-iommu.h and amd-iommu.h. Follow the same standard for omap-iommu.h. This is needed because we are removing plat and mach includes for ARM common zImage support. Further work should continue in the iommu framework context as only pure platform data will be communicated from arch/arm/*omap*/* code to the iommu framework.

2012-11-20ARM: OMAP: Merge iommu2.h into iommu.hIdo Yariv1-5/+83
Since iommu is not supported on OMAP1 and will not likely to ever be supported, merge plat/iommu2.h into iommu.h so only one file would have to move to platform_data/ as part of the single zImage effort.

2012-09-24ARM: OMAP3: hwmod data: add mmu data for iva and ispPaul Walmsley1-0/+13
Add mmu hwmod data for iva and isp. Due to compatibility an ifdef CONFIG_OMAP_IOMMU_IVA2 needs to be propagated (previously on iommu resource info) to hwmod data in OMAP3, so users of iommu and tidspbridge can avoid issues of two modules managing mmu data/irqs/resets; this until tidspbridge can be migrated to iommu framework.

2012-09-24ARM: OMAP: iommu: fix including iommu.h without IOMMU_API selectedOmar Ramirez Luna1-0/+2
If included without IOMMU_API being selected it will break compilation: arch/arm/plat-omap/include/plat/iommu.h: In function 'dev_to_omap_iommu': arch/arm/plat-omap/include/plat/iommu.h:148: error: 'struct dev_archdata' has no member named 'iommu' This will be seen when hwmod includes iommu.h to get the structure for attributes.

2011-12-05iommu/omap: eliminate the public omap_find_iommu_device() methodOhad Ben-Cohen1-3/+2
Eliminate the public omap_find_iommu_device() method, and don't expect clients to provide the omap_iommu handle anymore. Instead, OMAP's iommu driver now utilizes dev_archdata's private iommu extension to be able to access the required iommu information. This way OMAP IOMMU users are now able to use the generic IOMMU API without having to call any omap-specific binding method. Update omap3isp appropriately.

2011-12-05ARM: OMAP: iommu: declare a private iommu binding structOhad Ben-Cohen1-0/+26
Declare an omap iommu private struct, which binds an iommu user to its iommu device. This struct should be placed at the iommu user's dev_archdata so generic IOMMU API can be used without having to utilize omap-specific plumbing anymore. While at it, provide an accessor method to ease the retrieval of the omap_iommu handle from a user device.

2011-09-14iommu/omap: Migrate to the generic fault report mechanismOhad Ben-Cohen1-2/+1
Start using the generic fault report mechanism, as provided by the IOMMU core, and remove its now-redundant omap_iommu_set_isr API. Currently we're only interested in letting upper layers know about the fault, so in case the faulting device is a remote processor, they could restart it. Dynamic PTE/TLB loading is not supported.

2011-08-26omap: iommu: omapify 'struct iommu' and exposed APIOhad Ben-Cohen1-25/+30
Prepend 'omap_' to OMAP's 'struct iommu' and exposed API, to prevent namespace pollution and generally to improve readability of the code that still uses the driver directly. Update the users as needed as well.

2011-08-26omap: iommu: remove unused exported APIOhad Ben-Cohen1-3/+0
Remove unused public APIs from OMAP's iommu driver. IOMMU functionality should be exposed only via the generic IOMMU API; this way drivers stay generic, and different IOMMU drivers don't need to duplicate similar functionalities. The rest of the API still exposed by OMAP's iommu will be evaluated and eventually either added to the generic IOMMU API (if relevant), or completely removed. The intention is that OMAP's iommu driver will eventually not expose any public API.

2011-08-26omap: iommu: stop exporting local functionsOhad Ben-Cohen1-8/+0

2011-08-26omap: iommu: migrate to the generic IOMMU APIOhad Ben-Cohen1-3/+2
Migrate OMAP's iommu driver to the generic IOMMU API, so users can stay generic, and any generic IOMMU functionality can be developed once in the generic framework. Migrate omap's iovmm (virtual memory manager) to the generic IOMMU API, and adapt omap3isp as needed, so the latter won't break. The plan is to eventually remove iovmm completely by replacing it with the (upcoming) IOMMU-based DMA-API. Tested on OMAP3 (with omap3isp) and OMAP4 (with rpmsg/remoteproc).

In order to enable TLB miss interrupt, the TWL should be disabled.
