| * net/designware: add support of max-speed device tree propertyAlexey Brodkin2016-01-28-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This property allows to specify fastest connection mode supported by the MAC (as opposed to features of the phy). There are situations when phy may handle faster modes than the MAC (or even it's particular implementation or even due to CPU being too slow). This property is a standard one in Linux kernel these days and some boards do already use it in their device tree descriptions.

| * net/designware: do explicit port selection for 1Gb modeAlexey Brodkin2016-01-28-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current implementation only sets "port select" bit for non-1Gb mode. That works fine if GMAC has just exited reset state but we may as well change connection mode in runtime. Then we'll need to reprogram GMAC for that new mode of operation and if previous mode was 10 or 100 Mb and new one is 1 Gb we'll need to reset port mode bit.

* dm: eth: Avoid blocking on packet receptionSimon Glass2015-07-21-1/+1
| | | | | | | | | | | | | | | | | | | | Some devices can take a long time to work out whether they have a new packet or now. For example the ASIX USB Ethernet dongle can take 5 seconds to do this, since it waits until it gets a new packet on the wire before allowing the USB bulk read packet to be submitted. At present with driver mode the Ethernet receive code reads 32 packets. This can take a very long time if we must wait for all 32 packets. The old code (before driver model) worked by reading a single set of packets from the USB device, then processing all the packets with in. It would be nice to use the same behaviour with driver model. Add a flag to the receive method which indicates that the driver should try to find a packet if available, by consulting the hardware. When the flag is not set, it should just return any packet data it has already received. If there is none, it should return -EAGAIN so that the loop will terminate.

* net/designware - switch driver to phylib usageAlexey Brodkin2014-02-07-311/+149
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this change driver will benefit from existing phylib and thus custom phy functionality implemented in the driver will go away: * Instantiation of the driver is now much shorter - 2 parameters instead of 4. * Simplified phy management/functoinality in driver is replaced with rich functionality of phylib. * Support of custom phy initialization is now done with existing "board_phy_config". Note that after this change some previously used config options (driver-specific PHY configuration) will be obsolete and they are simply substituted with similar options of phylib. For example: * CONFIG_DW_AUTONEG - no need in this one. Autonegotiation is enabled by default. * CONFIG_DW_SEARCH_PHY - if one wants to specify attached phy explicitly CONFIG_PHY_ADDR board config option has to be used, otherwise automatically the first discovered on MDIO bus phy will be used I believe there's no need now in "doc/README.designware_eth" because user only needs to instantiate the driver with "designware_initialize" whose prototype exists in "include/netdev.h".

| | | | | | | | | | | | | | | | | | Driver "init" function might be called multiple times. On every "init" Tx/Rx buffer descriptors are initialized: "descs_init" -> "{tx|rx}_descs_init". In its turn those init functions set MAC's "{tx|rx}desclistaddr" to point on the first buffer descriptor in the list. So CPU to start operation from the first buffer descriptor as well after every "init" we have to reset "{tx|rx}_currdescnum".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the following changes to designware ethernet driver found on the ST SPEAr SoC: - Don't init MAC & PHY upon startup. This causes a delay, waiting for the auto negotiation to complete. And we don't want this delay to always happen. Especially not on platforms where ethernet is not used at all (e.g. booting via flash). Instead postpone the MAC / PHY configuration to the stage, where ethernet is first used. - Add possibility for board specific PHY init code. This is needed for example on the X600 board, where the Vitesse PHY needs to be configured for GMII mode. This board specific PHY init is done via the function designware_board_phy_init(). And this driver now adds a weak default which can be overridden by board code. - Use common functions miiphy_speed() & miiphy_duplex() to read link status from PHY. - Print status and progress of auto negotiation. - Print link status (speed, dupex) upon first usage.
