◆ no_os_mdio_init()
Initialize the MDIO interface.
- Parameters
-
| desc | - The MDIO descriptor. |
| param | - MDIO parameters. |
- Returns
- 0 in case of success, error code otherwise.

( |
struct no_os_mdio_desc * | desc, |
|
|
uint32_t | reg, |

|
uint16_t * | val ) |
Read a register using MDIO.
- Parameters
-
| desc | - The MDIO descriptor. |
| reg | - Register address. For clause 45 reg is constructed using NO_OS_MDIO_C45_ADDR macro. It is otherwise the plain clause 22 address (0...31). |
| val | - Value read from register. |
- Returns
- 0 in case of success, error code otherwise.
◆ no_os_mdio_remove()
Free the resources allocated by no_os_mdio_init().
- Parameters
-
| desc | - The MDIO descriptor. |
- Returns
- 0 in case of success, error code otherwise.

( |
struct no_os_mdio_desc * | desc, |
|
|
uint32_t | reg, |

Write a register using MDIO.
- Parameters
-
| desc | - The MDIO descriptor. |
| reg | - Register address. For clause 45 reg is constructed using NO_OS_MDIO_C45_ADDR macro. It is otherwise the plain clause 22 address (0...31). |
| val | - Value to write into register. |
- Returns
- 0 in case of success, error code otherwise.
