* ARM: SAMSUNG: Add soc_is_s3c6400/s3c6410 macrosTomasz Figa2013-09-161-0/+4
| | | | | | | | | This patch adds soc_is_s3c6400() and soc_is_s3c6410() macros that allow to distinguish between specific SoCs from s3c64xx series that is needed to handle differences between them. Signed-off-by: Tomasz Figa <tomasz.figa@gmail.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

* ARM: S3C24XX: move s3c24xx_init_irq to s3c2410_init_irqHeiko Stuebner2013-03-071-1/+0
| | | | | | | | | | | | | | The s3c24xx_init_irq function that was the base for all irq inits is now only used to initialize the real s3c2410 irqs. Therefore rename it and also move its declaration from plat/cpu.h to common.h The eint declaration is used by the vast majority of the SoCs and gets therefore placed outside any ifdefs.

* | ARM: delete struct sys_timerStephen Warren2012-12-241-2/+1
|/ | | | | | | | | | | | | | | | | | Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

* ARM: EXYNOS: Remove a new bus_type instance for EXYNOS5Thomas Abraham2012-05-161-1/+1
| | | | | | | | | | | | | A seperate bus_type instance is not required for EXYNOS5. The existing bus_type instance used with EXYNOS4 is sufficient for both EXYNOS4 and EXYNOS5. 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.

* ARM: S3C64XX: Fix SoC identification for S3C64xx devicesMark Brown2011-10-181-3/+3
| | | | | | | | | | | | | | | The IS_SAMSUNG_CPU() macro works by comparing the CPU ID mask exactly with the CPU ID. This was failing for S3C64xx SoCs as in order to support identification of the exact device the mask covers both variants of the chip, meaning that the test would always fail on S3C6410 devices. This in turn caused the core GPIO subsystem to fail to identify the CPU and not support any GPIOs, crippling the system. As a minimally invasive fix change the test for the class to be done by checking each implementation and oring them together.
