This is useful for generic drivers such as ahci-platform, +ehci-platoform and ohci-platform which have support for driving an optional +phy passed to them through the devicetree. + +Since on some boards this phy functionality is not needed, being able to +disable the phy subsystem without needing a lot of #ifdef magic in the +driver using it is quite useful. + +However this breaks when the module using the phy subsystem is build-in and +the phy-core is not, which leads to the build failing with missing symbol +errors in the linking stage of the zImage. + +Which leads to gems such as this being added to the Kconfig for achi_platform: + + depends on GENERIC_PHY || !GENERIC_PHY + +Rather then duplicating this code in a lot of places using the phy-core, +I believe it is better to simply not allow the phy-core to be built as a +module. The phy core is quite small and has no external dependencies, so +always building it in when enabling it should not be an issue. + +Signed-off-by: Hans de Goede <hdegoede@redhat.com> +--- + drivers/phy/Kconfig | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +diff --git a/drivers/phy/Kconfig b/drivers/phy/Kconfig +index afa2354..4ef8755 100644 +--- a/drivers/phy/Kconfig ++++ b/drivers/phy/Kconfig +@@ -5,7 +5,7 @@ + menu "PHY Subsystem" + + config GENERIC_PHY +- tristate "PHY Core" ++ bool "PHY Core" + help + Generic PHY support. + +-- +1.8.5.5 + |
