* tsec: fix the return value for tsec_eth_init()Timur Tabi2010-07-12-3/+12
| | | | | | | | | | | | | | The Ethernet initialization functions are supposed to return the number of devices initialized, so fix tsec_eth_init() so that they returns the number of TSECs initialized, instead of just zero. This is safe because the return value is currently ignored by all callers, but now they don't have to ignore it. In general, if an function initializes only one device, then it should return a negative number if there's an error. If it initializes more than one device, then it should never return a negative number. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>

* tsec: Fix eTSEC2 link problem on P2020RDBFelix Radensky2010-06-29-1/+5
| | | | | | | | | | | | On P2020RDB eTSEC2 is connected to Vitesse VSC8221 PHY via SGMII. Current TBI PHY settings for SGMII mode cause link problems on this platform, link never comes up. Fix this by making TBI PHY settings configurable and add a working configuration for P2020RDB. Signed-off-by: Felix Radensky <felix@embedded-sol.com> Acked-by: Andy Fleming <afleming@freescale.com>

* tsec: Add TSEC_FIBER flagPeter Tyser2010-01-31-2/+4
| | | | | | | | | | | | The TSEC_FIBER flag should be set when a PHY is operating with an external fiber interface. Currently it is only used to notify a user that the PHY is operating in fiber mode. A short description was also added to the other TSEC flag defines so that it is clear how they differ from one another.

* tsec: Force TBI PHY to 1000Mbps full duplex in SGMII modePeter Tyser2010-01-31-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | In SGMII mode the link between a processor's internal TBI PHY and an external PHY should always be 1000Mbps, full duplex. Also, the SGMII interface between an internal TBI PHY and external PHY does not support in-band auto-negotation. Previously, when configured for SGMII mode a TBI PHY would attempt to restart auto-negotation during initializtion. This auto-negotation between a TBI PHY and external PHY would fail and result in unusable ethernet operation. Forcing the TBI PHY and and external PHY to link at 1000Mbps full duplex in SGMII mode resolves this issue of auto-negotation failing. Note that 10Mbps and 100Mbps operation is still possible on the external side of the external PHY even when SGMII is operating at 1000Mbps. The SGMII interface still operates at 1000Mbps, but each byte of data is repeated 100 or 10 times for 10/100Mbps and the external PHY handles converting this data stream into proper 10/100Mbps signalling.

| | | | | | | | | | | | | | | | | Moved the mdio regs out of the tsec structure,and provided different offsets for tsec base and mdio base so that provision for etsec2.0 can be provided. This patch helps in providing the support for etsec2.0 In etsec2.0, the MDIO register space and the etsec reg space are different.

| | | | | | | | | | | | | | | | | | | | | Previously, waiting for auto-negotiation would only occur if a valid link had been detected.

* tsec: report when there is no vendor specific PHY supportPaul Gortmaker2009-03-09-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | Commit af1c2b84 added a generic phy support, with an ID of zero and a 32 bit mask; meaning that it will match on any PHY ID. The problem is that there is a test that checked if a matching PHY was found, and if not, it printed the non-matching ID. But since there will always be a match (on the generic PHY, worst case), this test will never trip. In the case of a misconfigured PHY address, or of a PHY that isn't explicitly supported outside of the generic support, you will never see the ID of 0xffffffff, or the ID of the real (but unsupported) chip. It will silently fall through onto the generic support. This change makes that test useful again, and ensures that the selection of generic PHY support doesn't happen without some sort of notice. It also makes it explicitly clear that the generic PHY must be last in the PHY table. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> Acked-by: Andy Fleming <afleming@freescale.com>

* tsec: Fix a bug in soft-resettingAndy Fleming2009-02-09-0/+1
| | | | | | | | | | SOFT_RESET must be asserted for at least 3 TX clocks. Usually, that's about 30 clock cycles, so it's been mostly working. But we had no guarantee, and at slower bitrates, it's just over a microsecond (over 1000 clock cycles). This enforces a 2 microsecond gap between assertion and deassertion.

* net: tsec: Fix Marvell 88E1121R phy initAnatolij Gustschin2008-12-04-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | This patch tries to ensure that phy interrupt pin won't be asserted after booting. We experienced following issues with current 88E1121R phy init: Marvell 88E1121R phy can be hardware-configured to share MDC/MDIO and interrupt pins for both ports P0 and P1 (e.g. as configured on socrates board). Port 0 interrupt pin will be shared by both ports in such configuration. After booting Linux and configuring eth0 interface, port 0 phy interrupts are enabled. After rebooting without proper eth0 interface shutdown port 0 phy interrupts remain enabled so any change on port 0 (link status, etc.) cause assertion of the interrupt. Now booting Linux and configuring eth1 interface will cause permanent phy interrupt storm as the registered phy 1 interrupt handler doesn't acknowledge phy 0 interrupts. This of course should be fixed in Linux driver too.

| | | | | | | | | | | | | The tsec driver contains a hard-coded array of configuration information for the tsec ethernet controllers. We create a default function that works for most tsecs, and allow that to be overridden by board code. It creates an array of tsec_info structures, which are then parsed by the corresponding driver instance to determine configuration. Also, add regs, miiregs, and devname fields to the tsec_info structure, so that we don't need the kludgy "index" parameter.
