2015-02-19net: eth: altera: Change reset_mac failure message masks from err to dbgVince Bridgers1-2/+10
This debug output is not really an error message since mac reset can fail if the phy clocks are gated, specifically when the phy has been placed in a powered down or isolation mode. The netdev output masks were changed from err to dbg, and comments added in the code. Signed-off-by: Vince Bridgers <vbridger@opensource.altera.com> Signed-off-by: David S.

2015-02-19net: eth: altera: Change access ports to mdio for all xMII applicationsVince Bridgers1-4/+4
Change use of Altera TSE's MDIO access from phy 0 registers to phy 1 registers. This allows support for GMII, MII, RGMII, and SGMII designs where the external PHY is always accesible through Altera TSE's MDIO phy 1 registers and Altera's PCS is accessible through MDIO phy 0 registers for SGMII applications.

2015-01-02Altera TSE: Add missing phydevKostya Belezko1-9/+6
Altera network device doesn't come up after ifconfig eth0 down ifconfig eth0 up The reason behind is clearing priv->phydev during tse_shutdown(). The phydev is not restored back at tse_open(). Resubmiting as to follow Tobias Klauser suggestion. phy_start/phy_stop are called on each ifup/ifdown and phy_disconnect is called once during the module removal.

2014-10-05Altera TSE: Add support for no PHYWalter Lozano1-0/+8
This patch avoids PHY and MDIO probing if no PHY chip is present. This is the case mainly in optical links where there is no need for PHY chip, and therefore no need of MDIO. In this scenario Ethernet MAC is directly connected to an optical module through an external SFP transceiver. Signed-off-by: Walter Lozano <walter@vanguardiasur.com.ar> Signed-off-by: David S.

2014-10-05Altera TSE: Move PHY get addr and MDIO createWalter Lozano1-21/+36
Move PHY get addr and MDIO create to a new function to improve readability and make it easier to avoid its usage. This will be useful for example in the case where there is no PHY chip. Signed-off-by: Walter Lozano <walter@vanguardiasur.com.ar> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-10-03net: ethernet: Remove superfluous ether_setup after alloc_etherdevTobias Klauser1-1/+0
There is no need to call ether_setup after alloc_ethdev since it was already called there. Follow commits c706471b2601 ("net: axienet: remove unnecessary ether_setup after alloc_etherdev") and 3c87dcbfb36c ("net: ll_temac: Remove unnecessary ether_setup after alloc_etherdev") and fix the pattern in all remaining ethernet drivers.

This patch fixes the many sparse errors and warnings contained in the initial submission of the Altera Triple Speed Ethernet driver, and a few minor cppcheck warnings. Changes are tested on ARM and NIOS2 example designs, and compile tested against multiple architectures.

Conflicts: drivers/net/ethernet/altera/altera_sgdma.c net/netlink/af_netlink.c net/sched/cls_api.c net/sched/sch_api.c The netlink conflict dealt with moving to netlink_capable() and netlink_ns_capable() in the 'net' tree vs. supporting 'tc' operations in non-init namespaces. These were simple transformations from netlink_capable to netlink_ns_capable. The Altera driver conflict was simply code removal overlapping some void pointer cast cleanups in net-next.

2014-04-30Altera TSE: Fix DMA secriptor length initializationTobias Klauser1-37/+37
sgdma_descrip is a function name as well as the name of a struct. In sgdma_initialize(), we should initialize the descriptor length field with the actual length of a descriptor not with the size of the function. In order to prevent such things from happening in the future, rename the function to sgdma_setup_descrip().

2014-04-26Altera TSE: Work around unaligned DMA receive packet issue with Altera SGDMAVince Bridgers6-51/+101
This patch works around a recently discovered unaligned receive dma problem with the Altera SGMDA. The Altera SGDMA component cannot be configured to DMA data to unaligned addresses for receive packet operations from the Triple Speed Ethernet component because of a potential data transfer corruption that can occur. This patch addresses this issue by utilizing the shift 16 bits feature of the Altera Triple Speed Ethernet component and modifying the receive buffer physical addresses accordingly such that the target receive DMA address is always aligned on a 32-bit boundary.
