Subject: [RFC 0/5] OMAP groundwork for IOMMU-based DMA API
Date: Sun, 25 Sep 2011 13:58:52 +0300 [thread overview]
Message-ID: <1316948337-7924-1-git-send-email-ohad@wizery.com> (raw)
Another step towards generic IOMMU support on OMAP: eliminating
the public omap-specific find_iommu_device API.
Instead, we now bind iommu clients with their respective iommu device
using a private iommu member which is added to ARM's dev_archdata.
With this in hand, generic IOMMU API users will now work on OMAP without
utilizing any omap-specific API.
The changes are tested on OMAP3 (with omap3isp) and OMAP4 (with
remoteproc/rpmsg).
This is still RFC (2nd patch is probably the least elegant).
Ohad Ben-Cohen (5):
ARM: dev_archdata: add private iommu extension
ARM: OMAP: omap_device: add a method to set iommu private archdata
ARM: OMAP: iommu: declare a private iommu binding struct
ARM: OMAP3: bind omap3isp_device to its iommu device
iommu/omap: eliminate the public omap_find_iommu_device() method
