From e324654294907a420ab3773efe8849a935f37bf0 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Mon, 16 Nov 2015 12:06:10 +0900 Subject: ARM: use "depends on" for SoC configs instead of "if" after prompt Many ARM sub-architectures use prompts followed by "if" conditional, but it is wrong. Please notice the difference between config ARCH_FOO bool "Foo SoCs" if ARCH_MULTI_V7 and config ARCH_FOO bool "Foo SoCs" depends on ARCH_MULTI_V7 These two are *not* equivalent! In the former statement, it is not ARCH_FOO, but its prompt that depends on ARCH_MULTI_V7. So, it is completely valid that ARCH_FOO is selected by another, but ARCH_MULTI_V7 is still disabled. As it is not unmet dependency, Kconfig never warns. This is probably not what you want. The former should be used only when you need to do so, and you really understand what you are doing. (In most cases, it should be wrong!) For enabling/disabling sub-architectures, the latter is always correct. As a good side effect, this commit fixes some entries over 80 columns (mach-imx, mach-integrator, mach-mbevu). [Arnd: I note that there is not really a bug here, according to the discussion that followed, but I can see value in being consistent and in making the lines shorter] Signed-off-by: Masahiro Yamada Acked-by: Maxime Ripard Acked-by: Nicolas Ferre Acked-by: Heiko Stuebner Acked-by: Patrice Chotard Acked-by: Liviu Dudau Acked-by: Krzysztof Kozlowski Acked-by: Jun Nie Acked-by: Matthias Brugger Acked-by: Simon Horman Acked-by: Gregory CLEMENT Acked-by: Shawn Guo Acked-by: Sebastian Hesselbarth Acked-by: Thierry Reding Acked-by: Krzysztof Halasa Acked-by: Maxime Coquelin Signed-off-by: Arnd Bergmann --- arch/arm/mach-meson/Kconfig | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'arch/arm/mach-meson/Kconfig') diff --git a/arch/arm/mach-meson/Kconfig b/arch/arm/mach-meson/Kconfig index 5d56f86ae1a4..31bdd91098b6 100644 --- a/arch/arm/mach-meson/Kconfig +++ b/arch/arm/mach-meson/Kconfig @@ -1,5 +1,6 @@ menuconfig ARCH_MESON - bool "Amlogic Meson SoCs" if ARCH_MULTI_V7 + bool "Amlogic Meson SoCs" + depends on ARCH_MULTI_V7 select ARCH_REQUIRE_GPIOLIB select GENERIC_IRQ_CHIP select ARM_GIC -- cgit v1.2.3
