    Subject[PATCH 0/6] arm: omap iommu: add initial support
    Date
    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.
