| |
Currently the Exynos5433 (ARMv8 SoC) clock driver depends on ARCH_EXYNOS so it is built also on ARMv7. 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.

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 | 6 ++++++ drivers/clk/samsung/Makefile | 4 ++-- 2 files changed, 8 insertions(+), 2 deletions(-)
