net: phy: add paged PHY register accessors

2025-10-22T12:28:33+00:00

Synchronize paged PHY helpers with Linux v6.17.

Add support for PHY devices that use paged register access by
implementing the following functions:
- phy_save_page(): Save current page number
- phy_select_page(): Switch to a specific page and return previous page
- phy_restore_page(): Restore previously saved page

Also adds read_page and write_page callbacks to the phy_driver
structure to enable driver-specific page handling.

These helpers allow safe access to paged PHY registers by ensuring
proper page selection and restoration,
even in error conditions, which will be used by the Airoha PHY driver.

net: phy: Port set/clear bits from Linux

2025-03-19T02:38:51+00:00

To simply porting phy drivers from Linux to U-Boot, define
phy_set_bits() and phy_clear_bits() functions with a similar API to
those used in Linux.

The U-Boot versions of these functions include the `devad` argument
which is not present in the Linux versions, to keep them aligned with
the other phy functions in U-Boot.

net: phy: Replace PHY_ANEG_TIMEOUT with Kconfig symbol

2024-06-13T22:27:07+00:00

Switch PHY_ANEG_TIMEOUT to CONFIG_PHY_ANEG_TIMEOUT Kconfig symbol.
This removes one more configuration headers option finalizes its
Kconfig symbol conversion. No functional change expected.

net: phy: Turn default auto-negotiation timeout into Kconfig symbol

2024-06-13T22:27:06+00:00

Let users configure default auto-negotiation timeout via Kconfig
instead of specifying it in board configuration headers. This is
the first step toward converting this to Kconfig fully, so far the
legacy PHY_ANEG_TIMEOUT in configuration headers takes precedence.

net: phy: Factor out PHY GPIO reset code

2024-03-26T23:58:26+00:00

Pull the PHY GPIO reset code into separate function, since
this is and will be reused multiple times. Set up default
reset assert and deassert timing to generous 20ms and 1ms
for maximum compatibility in case those DT properties are
missing.

net: mdio: Handle bus level GPIO Reset

Some platforms have bus level Reset controlled
by a GPIO line. If available then handle bus reset
via GPIO.

net: phy: nxp-c45-tja11xx: use local definion of features

2024-02-08T02:41:23+00:00

Use a local definition for the PHY features. PHY_100BT1_FEATURES are
not defined using the 100BaseT1 bit, so keep this workaround in the driver.

net: phy: Unpublish phy_connect_dev()

2023-06-10T11:34:05+00:00

The phy_connect_dev() is legacy API, now that there are no users,
make it internal to phy.c and unpublish it from headers.

net: phy: Make phy_interface_is_rgmii a switch statement

2023-05-05T21:48:44+00:00

Recent commit 75d28899e3e9 ("net: phy: Synchronize PHY interface modes
with Linux") reordered the enum definitions. This exposed a problem
in range checking functions to identify the interface type. Though
this specific api wasn't impacted (all the RGMII definitions remained
within range), this experience should be used to never to have to face
this kind of challenge again.

While it is possible for the phy drivers to use the enums directly,
drivers such as dp83867, dp83869, marvell, micrel_ksz90x1 etc use this
api.
