This does not bring any kind of benefit. There won't be a single kernel image for ARMv7 and ARMv8 SoCs (like multi_v7 for ARMv7). Instead build clock drivers only for respective SoC's architecture. Signed-off-by: Krzysztof Kozlowski --- Changes since v3: 1. Rebase on next-20160127. Changes since v2: 1. Follow Arnd's advice making EXYNOS_ARM64_COMMON_CLK user-visible when COMPILE_TEST is enabled. 2. Dropped accumulated tags because the logic is now different. Changes since v1: 1. Use one Kconfig symbol for clocks of all ARM64 SoCs (after discussion): EXYNOS_ARM64_COMMON_CLK. 2. Minor cleanups after Tomasz's comments. 3. Added tags: Chanwoo's, Sylwester's, Alim's and Tomasz's (the tags were given for v1 but assuming that change from 1. is not major enough to require re-tagging). --- drivers/clk/samsung/Kconfig | 5 +++++ drivers/clk/samsung/Makefile | 4 ++-- 2 files changed, 7 insertions(+), 2 deletions(-) diff --git a/drivers/clk/samsung/Kconfig b/drivers/clk/samsung/Kconfig index dd6093a33f84..5fd982d9f4d9 100644 --- a/drivers/clk/samsung/Kconfig +++ b/drivers/clk/samsung/Kconfig @@ -23,3 +23,8 @@ config S3C2443_COMMON_CLK bool "Samsung S3C2443 clock controller support" if COMPILE_TEST select COMMON_CLK_SAMSUNG +# ARM64 SoCs (e.g. Exynos5433, Exynos7): +config EXYNOS_ARM64_COMMON_CLK + bool "Samsung Exynos ARMv8-family clock controller support" if COMPILE_TEST + default ARM64 && COMMON_CLK_SAMSUNG + depends on (ARM64 && COMMON_CLK_SAMSUNG) || COMPILE_TEST diff --git a/drivers/clk/samsung/Makefile b/drivers/clk/samsung/Makefile index 5f6833ea355d..fc367d4b2902 100644 --- a/drivers/clk/samsung/Makefile +++ b/drivers/clk/samsung/Makefile @@ -10,11 +10,11 @@ obj-$(CONFIG_SOC_EXYNOS5250) += clk-exynos5250.o obj-$(CONFIG_SOC_EXYNOS5260) += clk-exynos5260.o obj-$(CONFIG_SOC_EXYNOS5410) += clk-exynos5410.o obj-$(CONFIG_SOC_EXYNOS5420) += clk-exynos5420.o -obj-$(CONFIG_ARCH_EXYNOS) += clk-exynos5433.o +obj-$(CONFIG_EXYNOS_ARM64_COMMON_CLK) += clk-exynos5433.o obj-$(CONFIG_SOC_EXYNOS5440) += clk-exynos5440.o obj-$(CONFIG_ARCH_EXYNOS) += clk-exynos-audss.o obj-$(CONFIG_ARCH_EXYNOS) += clk-exynos-clkout.o -obj-$(CONFIG_ARCH_EXYNOS7) += clk-exynos7.o +obj-$(CONFIG_EXYNOS_ARM64_COMMON_CLK) += clk-exynos7.o obj-$(CONFIG_S3C2410_COMMON_CLK)+= clk-s3c2410.o obj-$(CONFIG_S3C2410_COMMON_DCLK)+= clk-s3c2410-dclk.o obj-$(CONFIG_S3C2412_COMMON_CLK)+= clk-s3c2412.o -- 1.9.1
