/****************************************************************************
|
|
* Function: s32k3xx_phy_boardinitialize
|
|
*
|
|
* Description:
|
|
* Some boards require specialized initialization of the PHY before it can
|
|
* be be used. This may include such things as configuring GPIOs,
|
|
* resetting the PHY, etc. If CONFIG_S32K3XX_EMAC_PHYINIT is defined in
|
|
* the configuration then the board specific logic must provide
|
|
* s32k3xx_phyinitialize(); The i.MX RT Ethernet driver will call this
|
|
* function one time before it first uses the PHY.
|
|
*
|
|
* Input Parameters:
|
|
* intf - Always zero for now.
|
|
*
|
|
* Returned Value:
|
|
* OK on success; Negated errno on failure.
