2013-03-25ARM: EXYNOS: Migrate clock support to common clock frameworkThomas Abraham1-187/+0
Remove Samsung specific clock support in Exynos4/5 and migrate to use common clock framework.

2013-01-11ARM: EXYNOS: remove system mmu initialization from exynos treeCho KyongHo1-5/+4
This removes System MMU initialization from arch/arm/mach-exynos/ to move them to DT and the exynos-iommu driver except gating clock definitions. Signed-off-by: KyongHo Cho <pullip.cho@samsung.com> Acked-by: Kukjin Kim <kgene.kim@samsung.com> Signed-off-by: Joerg Roedel <joro@8bytes.org>
2012-07-17ARM: EXYNOS: Move G2D clock entries to clock-exynos4210.c fileSachin Kamat1-0/+37
G2D clock registers are different in EXYNOS4210 and EXYNOS4X12 SoCs. Hence moving the SoC specific G2D clock entries from common clock file (clock-exynos4.c) to EXYNOS4210 specific clock file (clock-exynos4210.c).

2012-04-04ARM: EXYNOS: Change System MMU platform device definitionsKyongHo Cho1-0/+11
Handling System MMUs with an identifier is not flexible to manage System MMU platform devices because of the following reasons: 1. 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 <pullip.cho@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
2012-03-11ARM: EXYNOS: change the prefix S5P_ to EXYNOS4_ for clockKukjin Kim1-23/+21
This patch changes prefix of the clk register from S5P_ to EXYNOS4_ for new EXYNOS SoCs such as EXYNOS5 and adds prefix exynos4_ on clk declarations. Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
2012-03-11ARM: EXYNOS: replace clock.c for other new EXYNOS SoCsKukjin Kim1-1/+1
This patch changes the name of clock.c to clock-exynos4.c for other EXYNOS series such as EXYNOS5. And since the header file of clock is used only in arch/arm/mach-exynos, moves it in the local directory. Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

2012-01-03ARM: 7257/1: EXYNOS: introduce arch/arm/mach-exynos/common.[ch]Kukjin Kim1-1/+2
This patch introduces common.[ch] which are used only in the arch/arm/mach-exynos/ directory. The common.c file merges the cpu.c, init.c, irq-combiner.c and irq-eint.c files which are used commonly on EXYNOS SoCs and the common.h file replaces with plat/exynos4.h file.

2011-11-06ARM: EXYNOS: Add ARCH_EXYNOS and reorganize arch/arm/mach-exynosKukjin Kim1-0/+139
The arch/arm/mach-exynos4 directory (CONFIG_ARCH_EXYNOS4) has made for plaforms based on EXYNOS4 SoCs. But since upcoming Samsung's SoCs such as EXYNOS5 (ARM Cortex A15) can reuse most codes in current mach-exynos4, one mach-exynos directory will be used for them. This patch changes to CONFIG_ARCH_EXYNOS (arch/arm/mach-exynos) but keeps original CONFIG_ARCH_EXYNOS4 in mach-exynos/Kconfig to avoid changing in driver side.
