Subject: [PATCH 1/2] phy: mv88e61xx: add support for RGMII TX/RX delay
|
|
|
|
Clock delay in RGMII is required for some boards.
|
|
This patch introduce CONFIG_MV88E61XX_CPU_PORT_TX_DELAY and
|
|
CONFIG_MV88E61XX_CPU_PORT_RX_DELAY defines, which are setting
|
|
proper bits in PORT_REG_PHYS_CTRL register.
