2014-03-12ARM: dts: OMAP5: Add IOMMU nodesSuman Anna

2014-03-12ARM: OMAP2+: use pdata quirks for iommu reset linesSuman Anna
The OMAP iommu driver performs the reset management for the iommu instances in processor sub-systems using the omap_device API which are currently supplied as platform data ops. Use pdata quirks to maintain the functionality as the OMAP iommu driver gets converted to use DT nodes, until the reset portions are decoupled from omap_hwmod/omap_device into a separate reset driver. This patch adds the pdata quirks for the reset management of iommus within the DSP (OMAP3 & OMAP4) and IPU subsystems (OMAP4).

2014-03-12ARM: OMAP2+: change the ISP device archdata MMU name for DTSuman Anna
The IOMMU DT adaptation support uses the device name instead of an iommu object name. Fixup the ISP device archdata MMU name at runtime if using DT-boot. This allows the OMAP3 camera to be functional in both legacy and DT boots. The iommu object names should eventually vanish when all the IOMMU users have been converted to DT nodes.

2014-03-12ARM: OMAP3: fix iva mmu programming issuesSuman Anna
The IVA MMU is not functional when used through the hwmod and omap_device layers. Add fixes to clockdomain and hwmod data to have it functional. The hwmod changes are needed to enable the clock, and the SWSUP change is needed to wakeup the domain because the power domain is programmed to be in RET, and there is no automatic power domain switching to ON.

2014-03-12ARM: OMAP3: remove deprecated CONFIG_OMAP_IOMMU_IVA2Florian Vaussard
CONFIG_OMAP_IOMMU_IVA2 was defined originally to avoid conflicting usage by tidspbridge and other iommu users. The same can be achieved by marking the DT node disabled, so remove this obsolete flag and the corresponding hwmod data can be enabled.

If x86-sysfb platform-devices are removed from a system, we should properly unload vesafb. Otherwise, we end up releasing the parent while our vesa framebuffer is still running. This currently works just fine, but will cause problems on handover to real hw. So add the ->remove() callback and unregister vesafb.

omapdss has its own video-timings struct, but we want to move the common videomode. The first step is to change the omapdss's pixelclock unit from kHz to Hz. Also, omapdss uses "pixel_clock" field name, whereas the common videomode uses "pixelclock" field name.
