Subject: [PATCH 0/6] arm: omap iommu: add initial support
Date: Fri, 16 Jan 2009 10:37:04 +0200 [thread overview]
Message-ID: <20090116083003.18344.38307.stgit@oreo.research.nokia.com> (raw)
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.
