2014-09-23gpio: samsung: Remove remaining check for CONFIG_S5P_GPIO_DRVSTRPaul Bolle1-50/+0
Commit d78c16ccde96 ("ARM: SAMSUNG: Remove remaining legacy code") removed the Kconfig symbol S5P_GPIO_DRVSTR. It didn't remove one check for the related macro. Remove that check and the dead code it hides. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Reviewed-by: Tomasz Figa <tomasz.figa@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2013-12-20ARM: s3c64xx: get rid of custom <mach/gpio.h>Linus Walleij1-0/+3
This isolates the custom S3C64xx GPIO definition table to <linux/platform_data/gpio-samsung-s3x64xx.h> as this is used in a few different places in the kernel, removing the need to depend on the implicit inclusion of <mach/gpio.h> from <linux/gpio.h> and thus getting rid of a few nasty cross-dependencies. Also delete the CONFIG_SAMSUNG_GPIO_EXTRA stuff. Instead roof the number of GPIOs for this platform: First sum up all the GPIO banks from A to Q: 187 GPIOs. Add the 16 "board GPIOs" and the roof for SAMSUNG_GPIO_EXTRA, 128, so in total maximum 187+16+128 = 331 GPIOs, so let's take the same roof as for S3C24XX: 512. This way we can do away with the GPIO calculation macros for GPIO_BOARD_START, BOARD_NR_GPIOS and the definition of ARCH_NR_GPIOS.

2013-12-20ARM: s3c24xx: get rid of custom <mach/gpio.h>Linus Walleij1-0/+3

We also delete the nifty CONFIG_S3C24XX_GPIO_EXTRA stuff. The biggest this can ever be for the S3C24XX is CONFIG_S3C24XX_GPIO_EXTRA = 128, and then for CPU_S3C2443 or CPU_S3C2416 32*12 GPIOs are added, so 32*12+128 = 512 is the absolute roof value on this platform. So we set the size of ARCH_NR_GPIO to this and the GPIOs array will fit any S3C24XX platform, as per pattern from other archs. ChangeLog v2->v3: - Move the movement of the S3C64XX gpio.h file out of this patch and into the follow-up patch where it belongs. ChangeLog v1->v2: - Added an #ifdef ARCH_S3C24XX around the header inclusion in drivers/gpio/gpio-samsung.c as we would otherwise have colliding definitions when compiling S3C64XX. - Rename inclusion guard in the header file.

2013-05-21pinctrl: Add pinctrl-s3c24xx driverHeiko Stuebner1-0/+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.

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>

Pull ARM SoC cleanups from Arnd Bergmann: "A large number of cleanups, all over the platforms. 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.

Since EXYNOS5440 can select PINCTRL_EXYNOS5440 without PINCTRL_SAMSUNG, it should be fixed. In detail, PINCTRL_SAMSUNG is a kind of frame work for supporting pinctrl on most Samsung SoCs including S3C, S5P as well except EXYNOS5440 so PINCTRL_EXYNOS5440 has been implemented separated.

Until now the EXYNOS-SoC was the only Samsung-SoC supporting the GPIOs via the device tree. This patch implements dt-support for the s3c24xx arches. The controllers contain only 3 cells, as the underlying gpio controller does not support controlling the drive strength on a gpio level. Tested with the gpio-keys driver on a s3c2416 based machine.
