From e1f80f57443838f5f420c774744c50c81c178e2c Mon Sep 17 00:00:00 2001 From: KyongHo Cho Date: Wed, 4 Apr 2012 09:23:02 -0700 Subject: [PATCH 01/41] S5P: SYSMMU: Remove System MMU device driver This patch removes System MMU device driver from arm/plat-s5p tree for transition to implement IOMMU driver. Although controlling System MMU in this removing driver is similar to the new IOMMU driver in the following patch, the new one is almost rewrite of this driver and there is no benefit to moving the driver file from arch/arm/ to drivers/iommu.

A device driver which needs to handle System MMU must know the ID. 2. A System MMU may not present in some implementations of Exynos family. 3. Handling System MMU with IOMMU API does not require an ID. This patch is the result of removing ID of System MMUs. Instead, a device driver that needs to handle its System MMU must use IOMMU API while its descriptor of platform device is given. This patch also includes the following enhancements: - A System MMU device becomes a child if its power domain device. - clkdev Signed-off-by: KyongHo Cho Signed-off-by: Kukjin Kim ---

This patch introduces dma channel declarations for these and changes the dma-s3c2443.c accordingly. None of the older SoCs use the spi-dma at all. Most boards bitbang their spi use and the spi-s3c24xx driver also does not use the dma system.

This also solves issue of uninitialized usage of exynos4_subsys in EXYNOS4 power management code that is reused for EXYNOS5 also. In addition to that, the existing exynos4_subsys bus_type is renamed to exynos_subsys to indicate that it is reused on both EXYNOS4 and EXYNOS5 platforms.

The interrupt request from each group are connected to a parent +interrupt controller, such as GIC in case of Exynos4210. + +The interrupt combiner controller consists of multiple combiners. Upto eight +interrupt sources can be connected to a combiner. The combiner outputs one +combined interrupt for its eight interrupt sources.
