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 (285) than the default number of GPIOs (255).
Thus define this number in Kconfig file. 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]> --- Based on Kukjin's for-next tree. --- arch/arm/Kconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/arm/Kconfig b/arch/arm/Kconfig index ddf2667..380a53b 100644 --- a/arch/arm/Kconfig +++ b/arch/arm/Kconfig @@ -1578,6 +1578,7 @@ config ARCH_NR_GPIO default 512 if SOC_OMAP5 default 392 if ARCH_U8500 default 352 if ARCH_VT8500 + default 288 if ARCH_EXYNOS default 288 if ARCH_SUNXI default 264 if MACH_H4700 default 0 -- 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
