[PATCH v3 0/3] arm64/clk: EXYNOS: Consolidate Exynos7 symbol
From: Krzysztof Kozlowski
Date: Tue Jan 26 2016 - 03:05:46 EST
Third attempt to remove ARCH_EXYNOS7 symbol.
Patches cannot be cherry-picked. I was thinking about merging this
through arm-soc tree after getting needed acks (clk, arm-soc?).
Changes since v2:
1. Follow Arnd's advice about not enabling silently the newly added
EXYNOS_ARM64_COMMON_CLK, when COMPILE_TEST is enabled. This was
also a trigger for some changes in placement of Samsung clocks
2. ... which lead to introducing patch 1.
Now the clock selection algorithm works like:
1. For Exynos ARMv7 and ARMv8 the platforms select COMMON_CLK
2. As before: clock drivers for Exynos ARMv7 will be selected by
respective SOC/ARCH_EXYNOS_XXX symbol.
3. For Exynos ARMv8 the clock drivers will be enabled by default
by EXYNOS_ARM64_COMMON_CLK symbol.
We don't need ARCH_EXYNOS7 symbol because all ARMv8 platforms should
fall under generic ARCH_EXYNOS. In the same time there is no sense
in building clocks for these ARMv8 SoCs on ARMv7 builds. In future
this will also influence PMU  driver.
Krzysztof Kozlowski (3):
clk: samsung: Enable COMPILE_TEST for Samsung clocks
clk: samsung: Don't build ARMv8 clock drivers on ARMv7
