* gpio: samsung: Drop support for Exynos SoCsTomasz Figa2013-08-291-871/+0
| | | | | | | | | | GPIO support on Exynos SoCs is provided by pinctrl-samsung driver, leaving all the support code in gpio-samsung driver unused. This dead code can be safely removed and so it is done by this patch.

| * pinctrl: Add pinctrl-s3c24xx driverHeiko Stuebner2013-05-211-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The s3c24xx pins follow a similar pattern as the other Samsung SoCs and can therefore reuse the already introduced infrastructure. The s3c24xx SoCs have one design oddity in that the first 4 external interrupts do not reside in the eint pending register but in the main interrupt controller instead. We solve this by forwarding the external interrupt from the main controller into the irq domain of the pin bank. The masking/acking of these interrupts is handled in the same way. Furthermore the S3C2412/2413 SoCs contain another oddity in that they keep the same 4 eints in the main interrupt controller and eintpend register and requiring ack operations to happen in both. This is solved by using different compatible properties for the wakeup eint node which set a property accordingly.

|/ | | | | | | | | | | | | | | | There is no users of this code and there is already a pinctrl driver written for s3c24xx which is going to be used on any s3c24xx DT platforms. Hence this has been effectively a dead code in mainline.

|/ | | | | | | | | | | | | | | | | | | | | | The s3c2412 handles the eints 0 to 3 different than all the other SoCs of the 24xx range. These eints must be acked and masked in the regular bits as well as the bits 0 to 3 of the eint registers, which are unused on the other SoCs. This of course can be realized using the new infrastructure with the eint bits in the main register being the parent interrupts of the same bits in the eint register. The s3c2412 therefore gets its own IRQ_EINT0 to 4 constants that reside in the newly created gap before IRQ_EINT4. gpio-samsung, as the only user of these is modified to return the correct values when handling gpio_to_irq requests on s3c2412 based machines. Due to lack of hardware this is compile tested only, but should hopefully work as intended. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

This is dominated largely by the Samsung platforms (s3c, s5p, exynos) and a few of the others moving code out of arch/arm into more appropriate subsystems. The clocksource and irqchip drivers are now abstracted to the point where platforms that are already cleaned up do not need to even specify the driver they use, it can all get configured from the device tree as we do for normal device drivers. The clocksource changes basically touch every single platform in the process. We further clean up the use of platform specific header files here, with the goal of turning more of the platforms over to being "multiplatform" enabled, which implies that they cannot expose their headers to architecture independent code any more. It is expected that no functional changes are part of the cleanup. The overall reduction in total code lines is mostly the result of removing broken and obsolete code." * tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (133 commits) ARM: mvebu: correct gated clock documentation ARM: kirkwood: add missing include for nsa310 ARM: exynos: move exynos4210-combiner to drivers/irqchip mfd: db8500-prcmu: update resource passing drivers/db8500-cpufreq: delete dangling include ARM: at91: remove NEOCORE 926 board sunxi: Cleanup the reset code and add meaningful registers defines ARM: S3C24XX: header mach/regs-mem.h local ARM: S3C24XX: header mach/regs-power.h local ARM: S3C24XX: header mach/regs-s3c2412-mem.h local ARM: S3C24XX: Remove plat-s3c24xx directory in arch/arm/ ARM: S3C24XX: transform s3c2443 subirqs into new structure ARM: S3C24XX: modify s3c2443 irq init to initialize all irqs ARM: S3C24XX: move s3c2443 irq code to irq.c ARM: S3C24XX: transform s3c2416 irqs into new structure ARM: S3C24XX: modify s3c2416 irq init to initialize all irqs ARM: S3C24XX: move s3c2416 irq init to common irq code ARM: S3C24XX: Modify s3c_irq_wake to use the hwirq property ARM: S3C24XX: Move irq syscore-ops to irq-pm clocksource: always define CLOCKSOURCE_OF_DECLARE ...

| | | | | | | | | | | | | | | Move gpc4 to the end of the automatically processed gpio controllers so we don't taint the automatic offset calculation. This bug caused all controllers coming after gpc4 to map to the incorrect address. The result is <&gpd1 0 0 0 0> would actually map to GPIO 0 in gpd0.
