* net: keystone_net: increase PHY auto negotiate timeKhoronzhuk, Ivan2014-10-23-5/+31
| | | | | | | | | | | The new Marvel PHY (88E1514) used on K2L/K2E EVM requires longer time to auto negotiate with SoC's SGMII port. It can take about 3 sec to up the PHY after reset, so add code to expose sgmii auto negotiation waiting process.

* net: keystone_net: add Keystone2 K2E SoC supportKhoronzhuk, Ivan2014-10-23-0/+5
| | | | | | | | | The Keystone2 Edison SoC uses the same keystone net driver. This patch adds opportunity to use it by K2E SoCs. Acked-by: Vitaly Andrianov <vitalya@ti.com> Acked-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@ti.com>

* net: keystone_net: use general get link functionKhoronzhuk, Ivan2014-10-23-45/+5
| | | | | | | | | | | | The phy framework has function to get link, so use it instead of own implementation. There is no reason to check SGMII link while sending each packet, phy link is enough. Check SGMII link only while ethernet open. Acked-by: Vitaly Andrianov <vitalya@ti.com> Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@ti.com>
* net: keystone_net: register eth PHYs on MDIO busKhoronzhuk, Ivan2014-10-23-3/+21
| | | | | | | | | | | | | | | | | As MDIO bus has been added we can register PHYs with it. After registration, the PHY driver will be probed according to the hardware on board. Startup PHY at the ethernet open. Use phy_startup() instead of keystone_get_link_status() when eth open, as it verifies PHY link inside and SGMII link is checked before. For K2HK evm PHY configuration at init was absent, so don't enable phy config at init for k2hk evm. Acked-by: Vitaly Andrianov <vitalya@ti.com> Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@ti.com>
* net: keystone_net: register MDIO busKhoronzhuk, Ivan2014-10-23-38/+55
| | | | | | | | | | | | Currently MDIO framework is not used to configure Ethernet PHY. As result some of already implemented functions are duplicated. So register MDIO bus in order to use it. On that stage it's just registered, it'll be used as we start to use PHY framework. Use mdio bus read/write/reset functions in the driver.

* net: keystone_net: use mdio_reset functionKhoronzhuk, Ivan2014-10-23-14/+2
| | | | | | | | Don't use mdio_enable twice while eth open. Also rename it to keystone2_mdio_reset as more appropriate name. Acked-by: Vitaly Andrianov <vitalya@ti.com> Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@ti.com>
* soc: keystone_serdes: generalize to be used by other sub systemsHao Zhang2014-10-23-1/+14
| | | | | | | | | | SerDes driver is used by other sub systems like PCI, sRIO etc. So modify it to be more general. The SerDes driver provides common API's that can also be extended for other peripherals SerDes configurations.

* soc: keystone_serdes: create a separate SGMII SerDes driverKhoronzhuk, Ivan2014-10-23-138/+5
| | | | | | | | | | | | | This patch split the Keystone II SGMII SerDes related code from Ethernet driver and create a separate SGMII SerDes driver. The SerDes driver can be used by others keystone subsystems like PCI, sRIO, so move it to driver/soc/keystone directory. Add soc specific drivers directory like in the Linux kernel. It is going to be used by keysotone soc specific drivers. Signed-off-by: Hao Zhang <hzhang@ti.com> Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@ti.com>
* net: keystone_net: remove redundant code from keystone_net.cKhoronzhuk, Ivan2014-10-23-17/+0
| | | | | | | | | | | | | | | | Remove unused tx_send_loop variable. Removes duplicated get_link_status() call from the keystone2_eth_send_packet(). The emac_gigabit_enable() is called at opening Ethernet and there is no need to enable it on sending each packet. So remove that call from keystone2_eth_send_packet() as well. The calling of power/clock up functions are mostly the responsibility of SoC/board code, so move these functions to appropriate place. Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@ti.com>
* net: keystone_net: move header file from arch to ti-commonKhoronzhuk, Ivan2014-10-23-1/+1
| | | | | | | | | | The header file for the driver should be in correct place. So move it to "arch/arm/include/asm/ti-common/keystone_net.h" and correct driver's external dependencies. At the same time align and correct some definitions. Acked-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@ti.com>
* net: keystone_net: remove SoC specific emac_regs structureHao Zhang2014-10-23-5/+3
| | | | | | | | | | This patch removes K2HK SOC specifc emac_regs structure, it uses soc specific register offset to keep the network driver common across all the Keystone II EVMs. Acked-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: Hao Zhang <hzhang@ti.com> Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@ti.com>
* dma: keystone_nav: generalize driver usageKhoronzhuk, Ivan2014-10-23-6/+7
| | | | | | | | | | | | | | | | | | | The keystone_nav driver is general driver intended to be used for working with queue manager and pktdma for different IPs like NETCP, AIF, FFTC, etc. So the it's API shouldn't be named like it works only with one of them, it should be general names. The names with prefix like netcp_* rather do for drivers/net/keystone_net.c driver. So it's good to generalize this driver to be used for different IP's and delete confusion with real NETCP driver. The current netcp_* functions of keystone navigator can be used for other settings of pktdma, not only for NETCP. The API of this driver is used by the keystone_net driver to work with NETCP, so net driver also should be corrected. For convenience collect pkdma configurations in drivers/dma/keystone_nav_cfg.c.

* dma: keystone_nav: move keystone_nav driver to driver/dma/Khoronzhuk, Ivan2014-10-23-1/+1
| | | | | | | | | | | | | | The keystone_nav is used by drivers/net/keystone_net.c driver to send and receive packets, but currently it's placed at keystone arch sources. So it should be in the drivers directory also. It's separate driver that can be used for sending and receiving pktdma packets by others drivers also. This patch just move this driver to appropriate directory and doesn't add any functional changes.

* keystone2: net: add keystone ethernet driverKaricheri, Muralidharan2014-04-17-0/+716
Ethernet driver configures the CPSW, SGMI and Phy and uses the the Navigator APIs. The driver supports 4 Ethernet ports and can work with only one port at a time. Port configurations are defined in board.c. Signed-off-by: Vitaly Andrianov <vitalya@ti.com> Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: WingMan Kwok <w-kwok2@ti.com>
