[PATCH 5/8] phy-core: phy_get: Leave error logging to the caller

[Kishon Vijay Abraham I]

From: Hans de Goede <hdegoede@redhat.com>

In various cases errors may be expected, ie probe-deferral or a call to
phy_get from a driver where the use of a phy is optional.

Rather then adding all sort of complicated checks for this, and/or adding
special functions like devm_phy_get_optional, simply don't log an error,
and let deciding if get_phy returning an error really should result in a
dev_err up to the caller.

[PATCH 6/8] phy-core: Don't propagate -ENOSUPP from phy_pm_runtime_get_sync to caller

From: Hans de Goede <hdegoede@redhat.com>

The phy-core allows phy_init and phy_power_on to be called multiple times,
but before this patch -ENOSUPP from phy_pm_runtime_get_sync would be
propagated to the caller for the 2nd and later calls.

[PATCH 7/8] phy-core: Don't allow building phy-core as a module

[Kishon Vijay Abraham I]

From: Hans de Goede <hdegoede@redhat.com>

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.

[PATCH 8/8] phy: let phy_provider_register be the last step in registering PHY

[Kishon Vijay Abraham I]

Registering phy_provider before creating the PHY can result in PHY
callbacks being invoked which will lead to aborts. In order to avoid this
invoke phy_provider_register after phy_create and phy_set_drvdata.

Is this a signed tag?  It doesn't look like it from this side, so it
would be great if you could redo it as a signed tag so I "know" I'm
pulling the right thing in the future.

For now, I'll just take the "raw" patches.
