This also enables i2c-s3c2410 for arm64 Exynos SoCs, which is required for example by Exynos850. This is basically continuation of work made in following commits: - commit d96890fca9fd ("rtc: s3c: remove HAVE_S3C_RTC in favor of direct dependencies") - commit 7dd3cae90d85 ("ARM: samsung: remove HAVE_S3C2410_WATCHDOG and use direct dependencies") Signed-off-by: Sam Protsenko --- arch/arm/Kconfig | 1 - arch/arm/mach-exynos/Kconfig | 1 - arch/arm/mach-s3c/Kconfig.s3c64xx | 1 - arch/arm/mach-s5pv210/Kconfig | 1 - drivers/i2c/busses/Kconfig | 10 ++-------- 5 files changed, 2 insertions(+), 12 deletions(-) diff --git a/arch/arm/Kconfig b/arch/arm/Kconfig index 59baf6c132a7..4536fb89b826 100644 --- a/arch/arm/Kconfig +++ b/arch/arm/Kconfig @@ -474,7 +474,6 @@ config ARCH_S3C24XX select GPIO_SAMSUNG select GPIOLIB select GENERIC_IRQ_MULTI_HANDLER - select HAVE_S3C2410_I2C if I2C select HAVE_S3C_RTC if RTC_CLASS select NEED_MACH_IO_H select S3C2410_WATCHDOG diff --git a/arch/arm/mach-exynos/Kconfig b/arch/arm/mach-exynos/Kconfig index 5a48abac6af4..0aa45d84ddf2 100644 --- a/arch/arm/mach-exynos/Kconfig +++ b/arch/arm/mach-exynos/Kconfig @@ -21,7 +21,6 @@ menuconfig ARCH_EXYNOS select GPIOLIB select HAVE_ARM_ARCH_TIMER if ARCH_EXYNOS5 select HAVE_ARM_SCU if SMP - select HAVE_S3C2410_I2C if I2C select HAVE_S3C_RTC if RTC_CLASS select PINCTRL select PINCTRL_EXYNOS diff --git a/arch/arm/mach-s3c/Kconfig.s3c64xx b/arch/arm/mach-s3c/Kconfig.s3c64xx index f3fcb570edf5..af01675d8769 100644 --- a/arch/arm/mach-s3c/Kconfig.s3c64xx +++ b/arch/arm/mach-s3c/Kconfig.s3c64xx @@ -12,7 +12,6 @@ menuconfig ARCH_S3C64XX select COMMON_CLK_SAMSUNG select GPIO_SAMSUNG if ATAGS select GPIOLIB - select HAVE_S3C2410_I2C if I2C select HAVE_TCM select PLAT_SAMSUNG select PM_GENERIC_DOMAINS if PM diff --git a/arch/arm/mach-s5pv210/Kconfig b/arch/arm/mach-s5pv210/Kconfig index d644b45bc29d..68f77d724bd5 100644 --- a/arch/arm/mach-s5pv210/Kconfig +++ b/arch/arm/mach-s5pv210/Kconfig @@ -12,7 +12,6 @@ config ARCH_S5PV210 select CLKSRC_SAMSUNG_PWM select COMMON_CLK_SAMSUNG select GPIOLIB - select HAVE_S3C2410_I2C if I2C select HAVE_S3C_RTC if RTC_CLASS select PINCTRL select PINCTRL_EXYNOS diff --git a/drivers/i2c/busses/Kconfig b/drivers/i2c/busses/Kconfig index e17790fe35a7..598becce03f0 100644 --- a/drivers/i2c/busses/Kconfig +++ b/drivers/i2c/busses/Kconfig @@ -949,16 +949,10 @@ config I2C_RK3X This driver can also be built as a module.
