ARM: EXYNOS: Update CONFIG_ARCH_NR_GPIO for Exynos
With the recent cleanup in Exynos platform code notably commits 17859bec ("ARM: EXYNOS: Do not select legacy Kconfig symbols any more") and b9222210 ("ARM: EXYNOS: Remove mach/gpio.h"), the definition of ARCH_NR_GPIOS got removed. 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 <sachin.kamat@linaro.org> Cc: Tomasz Figa <t.figa@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
