This is the second try of submitting patches about IOMMU/System MMU
driver for Exynos4 SoCs with the fixes of the following probles
pointed by Russell King.:
- Missing unlocking a spinlock in exynos_iommu_attach_dev().
- atomic_t -> int in sysmmu_drvdata.activations
- sysmmu_platdata -> sysmmu_drvdata
- Change in error messages in irq handler
- Removed casting in format of error message
- omap_iommu_ops -> exynos_iommu_ops in the last patch.
First 2 patches enhance System MMU platform device definition:
- Removed System MMU for MDMA0 in LCD block because it is not used.
Use MDMA2 in TOP block.
- Removed System MMU ID. Instead a System MMU is bound to a device that
the System MMU is dedicated during machin initialization. If a device
driver wants to handle System MMU, it must bind its device with System
MMU with sysmmu_set_owner().
- clkdev
- System MMU device driver is removed from arch/arm/plat-s5p to move it
to driver/iommu directory.
Last 2 patches implements IOMMU API:
- Implements IOMMU API and System MMU driver that is moved from
arch/arm/plat-s5p.
- Implements fault handling that is suggested by Ohad.
- Used bus_set_iommu instead of register_iommu that is suggested by Joerg.
Regards,
Cho KyongHo.

I am sorry :(
My mailer converted tabs into spaces.
Moreover, git send-email is not available now.
I stopped sending patches after sending "[PATCH 1/4 v2]".
I will submit the complete patches after everything becomes OK.
Sorry for disrupting.
Regards,
Cho KyongHo.
