include/phy/phy.h has stub code in there for when building without the phy-core enabled. 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.

Generic PHY support.
|
|
|
|
This framework is designed to provide a generic interface for PHY
|
|
devices present in the kernel. This layer will have the generic
|
|
API by which phy drivers can create PHY using the phy framework and
|
|
phy users can obtain reference to the PHY. All the users of this
|
|
framework should select this config.
