phy: Return success from generic_setup_phy() when phy is not found

2023-09-13T19:52:21+00:00

Restore the old behavior of ehci_setup_phy() and ohci_setup_phy() to
return success when generic_phy_get_by_index() return -ENOENT.

phy: Fix generic_setup_phy() return value on power on failure

2023-09-13T19:52:21+00:00

generic_phy_exit() typically return 0 for a struct phy that has been
initialized with a generic_phy_init() call.

generic_setup_phy() returns the value from a generic_phy_exit() call
when generic_phy_power_on() fails. This hides the failed state of the
power_on ops from the caller of generic_setup_phy().

Fix this by ignoring the return value of the generic_phy_exit() call and
return the value from the generic_phy_power_on() call.

phy: Set phy->dev to NULL when generic_phy_get_by_index_nodev() fails

2023-09-13T19:52:20+00:00

Generic phy helpers typically use generic_phy_valid() to determine if
the helper should perform its function on a passed struct phy.
generic_phy_valid() treat any struct phy having phy->dev set as valid.

With generic_phy_get_by_index_nodev() setting phy->dev to a valid struct
udevice early, there can be situations where the struct phy is returned
as valid when initialization in fact failed and returned an error.

Fix this by setting phy->dev back to NULL when any of the calls to
of_xlate ops, device_get_supply_regulator or phy_alloc_counts fail. Also
extend the dm_test_phy_base test with a test where of_xlate ops fail.

phy: Set phy->dev to NULL when generic_phy_get_by_name() fails

2023-09-13T19:52:20+00:00

generic_phy_get_by_name() does not initialize phy->dev to NULL before
returning when dev_read_stringlist_search() fails. This can lead to an
uninitialized or reused struct phy erroneously be report as valid by
generic_phy_valid().

Fix this issue by initializing phy->dev to NULL, also extend the
dm_test_phy_base test with calls to generic_phy_valid().

phy: add support for phy-supply

2023-05-17T09:36:18+00:00

Some phys require a phy-supply property that is a phandle to a regulator
that needs to be enabled for phy operations.
Implement basic supply lookup, enable and disabling, if DM_REGULATOR is
available.

phy: Add .set_mode and .set_speed callbacks

2023-04-07T12:23:26+00:00

Add two new callbacks matching the Linux ones. The .set_mode is used to set
PHY mode and submode, where mode is either USB, Ethernet, and so on, while
submode is e.g. for Ethernet case RGMII, RMII, and so on. The .set_speed is
used to configure link speed into the PHY. Unlike the existing configure
callback, which is used to pass arbitrary custom information to the PHY,
these two callbacks are used to pass standardized set of information to
the PHY.
