This started causing problems on SoCs like Exynos4412 which have more than the default number of GPIOs. Thus define this number in KConfig file which takes care of current SoC requirements and provides scope for GPIO expanders. Without this patch we get the following errors during boot: gpiochip_add: gpios 251..258 (gpv0) failed to register samsung-pinctrl 106e0000.pinctrl: failed to register gpio_chip gpv0, error code: -22 samsung-pinctrl: probe of 106e0000.pinctrl failed with error -22 Signed-off-by: Sachin Kamat Cc: Tomasz Figa Signed-off-by: Kukjin Kim --- diff --git a/arch/arm/Kconfig b/arch/arm/Kconfig index ba412e0..37c0f4e 100644 --- a/arch/arm/Kconfig +++ b/arch/arm/Kconfig @@ -1600,8 +1600,7 @@ config LOCAL_TIMERS config ARCH_NR_GPIO int default 1024 if ARCH_SHMOBILE || ARCH_TEGRA - default 512 if SOC_OMAP5 - default 512 if ARCH_KEYSTONE + default 512 if ARCH_EXYNOS || ARCH_KEYSTONE || SOC_OMAP5 default 392 if ARCH_U8500 default 352 if ARCH_VT8500 default 288 if ARCH_SUNXI
