phy: core: Remove unused phy_pm_runtime_(allow|forbid)

2025-03-10T07:28:07+00:00

phy_pm_runtime_allow() and phy_pm_runtime_forbid() were added in 2013
as part of
commit ff764963479a ("drivers: phy: add generic PHY framework")
but have remained unused.

Remove them.
Fix up the (English) docs - I've left the Chinese translation.

phy: Add devm_of_phy_optional_get() helper

2023-02-03T05:22:49+00:00

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()

2023-02-03T05:22:49+00:00

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.

doc: phy: Document typical order of API calls

2022-11-07T04:50:25+00:00

Document the typical order of API calls to used by new drivers and
controllers. Many existing controllers follow this order, but some do
not. This is especially true for controllers designed to work with one
particular PHY driver, which may not need a call to (for example)
phy_init.
