phy: Add devm_of_phy_optional_get() helper

2023-02-03T05:22:49Z

Add an optional variant of devm_of_phy_get() that also takes care of printing real errors, so drivers no longer have to open-code this operation.

phy: Remove unused phy_optional_get()

2023-02-03T05:22:49Z

There were never any upstream users of this function since its introduction almost 10 years ago. Besides, the dummy for phy_optional_get() should have returned NULL instead of an error code.

phy: core: Warn when phy_power_on is called before phy_init

2022-04-20T09:15:15Z

A warning when the order of phy operation is mixed up by drivers, this is an atempt to make the phy usage more uniform across (usb) drivers.

Update the syntax used by the documentation of phy operation functions. This is to unify the syntax with the newly added documentation. Signed-off-by: Jules Maselbas Link: https://lore.kernel.org/r/20220407102108.24211-3-jmaselbas@kalray.eu Signed-off-by: Vinod Koul

phy: core: Add documentation of phy operation order

2022-04-20T09:15:15Z

Add documentation on phy function usage: init function must be called before power_on; power_off must be called before exit.

phy: Allow a NULL phy name for devm_phy_get()

2021-05-14T12:18:41Z

For a single PHY, there's no reason to have a phy-names entry in DT. The DT specific get functions allow for this already, but devm_phy_get() WARNs in this case. Other subsystems also don't warn in their get functions. Let's drop the WARN for DT case in devm_phy_get().

phy: core: Fix phy_get() to not return error on link creation failure

2020-02-19T10:32:02Z

commit 987351e1ea77 ("phy: core: Add consumer device link support") added device link support between PHY consumer and PHY provider. However certain peripherals (DWC3 ULPI) have cyclic dependency between the PHY provider and PHY consumer causing the device link creation to fail. Instead of erroring out on failure to create device link, only add a debug print to indicate device link creation failed to get USB working again in multiple platforms.
