Merge branch 'xgene_txrx_delay'
Iyappan Subramanian says: ==================== drivers: xgene: Add support RGMII TX/RX delay configuration X-Gene RGMII ethernet controller has a RGMII bridge that performs the task of converting the RGMII signal {RX_CLK,RX_CTL, RX_DATA[3:0]} from PHY to GMII signal {RX_DV,RX_ER,RX_DATA[7:0]} and vice versa. This RGMII bridge has a provision to internally delay the input RX_CLK and the output TX_CLK using configuration registers. This will help in maintain the CLK-CTL delay relationship in various operating conditions. This patch adds support RGMII TX/RX delay configuration. ==================== Signed-off-by: Iyappan Subramanian <isubramanian@apm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
