2014-07-29ARM: omap: Don't set iommu pdata da_start and da_end fieldsLaurent Pinchart1-2/+0
The fields are not used by the driver and will be removed from platform data. Don't set them. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Joerg Roedel <jroedel@suse.de>
2014-03-04iommu/omap: Add devicetree supportFlorian Vaussard1-0/+5
As OMAP2+ is moving to a full DT boot for all SoC families, commit 7ce93f3 "ARM: OMAP2+: Fix more missing data for omap3.dtsi file" adds basic DT bits for OMAP3. But the driver is not yet converted, so this will not work and driver will not be probed. Convert it! The legacy boot mode is still supported until OMAP3 is converted to DT-boot only.

2013-02-09ARM: OMAP2+: Make sure files with omap initcalls include soc.hTony Lindgren1-0/+1
Looks like there are few more places that I missed that can cause compiler warnings. After grepping for omap initcall, all files needing soc.h should now have it.

2013-01-26ARM: OMAP2+: omap_device: remove obsolete pm_lats and early_device codePaul Walmsley1-2/+1
Remove now-obsolete code from arch/arm/mach-omap2/omap_device.c. This mostly consists of removing the first attempt at device PM latency handling. This was never really used, has been replaced by the common dev_pm_qos code, and needs to go away as part of the DT conversion. Also, the early platform_device creation code has been removed, as it appears to be unused. Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: Kevin Hilman <khilman@deeprootsystems.com>

2012-12-20ARM: OMAP2+: Trivial fix for IOMMU merge issueTony Lindgren1-2/+2
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.

2012-12-03iommu/omap: Adapt to runtime pmOmar Ramirez Luna1-1/+0
Use runtime PM functionality interfaced with hwmod enable/idle functions, to replace direct clock operations and sysconfig handling. 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.

Use hwmod data and device attributes to build and register an omap device for iommu driver. - Update the naming convention in isp module. - Remove unneeded check for number of resources, as this is now handled by omap_device and prevents driver from loading. - Now unused, remove platform device and resource data, handling of sysconfig register for softreset purposes, use default latency structure. - Use hwmod API for reset handling.

2012-09-12ARM: OMAP2+: Prepare for irqs.h removalTony Lindgren1-5/+7
As the interrupts should only be defined in the platform_data, and eventually coming from device tree, there's no need to define them in header files. Let's remove the hardcoded references to irqs.h and fix up the includes so we don't rely on headers included in irqs.h. Note that we're defining OMAP_INTC_START as 0 to the interrupts. This will be needed when we enable SPARSE_IRQ. For some drivers we need to add #include <plat/cpu.h> for now until these drivers are fixed to remove cpu_is_omapxxxx() usage. While at it, sort som of the includes the standard way, and add the trailing commas where they are missing in the related data structures. Note that for drivers/staging/tidspbridge we just define things locally. Cc: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

Irq and clock names were wrong for dsp iommu configuration for omap4. - Renamed tesla_ick to dsp_fck: This is required because the new naming convention introduced by: commit 0e43327 "OMAP4 clock: Fix clock names and align with hwmod names" - Renamed INT_44XX_DSP_MMU to OMAP44XX_IRQ_TESLA_MMU.
