Cover letter [PATCH 0/6] arm: omap iommu: add initial support
The following patches add initial support of omap iommu.
Some of TI OMAP series have the peripheral devices with their own MMU(iommu), which is composed of its own tlb and optional h/w pagetable(twl). These MMUs don't depend on mpu(arm) mmu at all, but their algorithms are somewhat similar and they share the same physical address space. This patch provides with common in-kernel iommu APIs such OMAP peripheral devices(Camera ISP, IVA1, IVA2, DSP and the equivalent ones in the latest OMAP successors) to handle peripheral device iommus in the same manner.
