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 <[email protected]> Cc: Tomasz Figa <[email protected]> --- Changes since v2: Changed the default number to 512 to accomodate GPIO exapnders. --- arch/arm/Kconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/arm/Kconfig b/arch/arm/Kconfig index ccc388d..b3c4fa4 100644 --- a/arch/arm/Kconfig +++ b/arch/arm/Kconfig @@ -1601,6 +1601,7 @@ config ARCH_NR_GPIO int default 1024 if ARCH_SHMOBILE || ARCH_TEGRA default 512 if SOC_OMAP5 + default 512 if ARCH_EXYNOS default 512 if ARCH_KEYSTONE default 392 if ARCH_U8500 default 352 if ARCH_VT8500 -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
