* net: phy: vitesse: add support for VSC8572Stephen Agate2016-12-021-0/+14
| | | | | | | | | | | | Add support for the Vitesse VSC8572 which is functionally equivalent to the already supported VSC8574. As such, all the same handling functions are used since the VSC8572 merely has half the number of phy blocks internally.

* net/phy/vitesse: Configure RGMII skew on VSC8601, if neededAlex2016-11-161-1/+33
| | | | | | | | | | | | | With RGMII, we need a 1.5 to 2ns skew between clock and data lines. The VSC8601 can handle this internally. While the VSC8601 can set more fine-grained delays, the standard skew settings work out of the box. The same heuristic is used to determine when this skew should be enabled as in vsc824x_config_init(). Tested on custom board with AM3352 SOC and VSC801 PHY.

* Revert "net/phy: Add Vitesse 8641 phy ID"Kevin Hao2015-09-211-14/+0Star
| | | | | | | | | | | | | | This reverts commit 1298267b548a78840bd4b3e030993ff8747ca5e6. That commit claim that the Vitesse VSC8641 is compatible with Vitesse 82xx. But this is not true. It seems that all the registers used in Vitesse phy driver are not compatible between 8641 and 82xx. It does cause malfunction of the Ethernet on p1010rdb-pa board. So we definitely need a rework in order to support the 8641 phy in this driver. Signed-off-by: Kevin Hao <haokexin@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* phylib: Modify Vitesse RGMII skew settingsAndy Fleming2011-10-191-12/+22
| | | | | | | | | | | | | | | | | The Vitesse driver was using the RGMII_ID interface type to determine if skew was necessary. However, we want to move away from using that interface type, as it's really a property of the board's PHY connection. However, some boards depend on it, so we want to support it, while allowing new boards to use the more flexible "fixups" approach. To do this, we extract the code which adds skew into its own function, and call that function when RGMII_ID has been selected. Another side-effect of this change is that if your PHY has skew set already, it doesn't clear it. This way, the fixup code can modify the register without config_init then clearing it.

* net/phy: fix many "defined but unused" warningsUwe Kleine-König2010-10-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | MODULE_DEVICE_TABLE only expands to something if it's compiled for a module. So when building-in support for the phys, the mdio_device_id tables are unused.

| | | | | | | | | | | | PHY is mostly compatible with the existing VSC8244 PHY. The init sequence is different and the interrupt mask lacks some bits present in the VSC8244. Rather than making a copy of the existing VSC234x config_intr function and change one constant, I modify it to select the interrupt mask based on which driver is calling it. This lets it be used by both drivers. Signed-off-by: Trent Piepho <tpiepho@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* Fix Vitesse 824x PHY interrupt ackingAndy Fleming2007-07-191-2/+21
| | | | | | | | | | | | | | | The Vitesse 824x PHY doesn't allow an interrupt to be cleared if the mask bit for that interrupt isn't set. This means that the PHY Lib's order of handling interrupts (disable, then clear) breaks on this PHY. However, clearing then disabling the interrupt opens up the code for a silly race condition. So rather than change the PHY Lib, we change the Vitesse driver so it always clears interrupts before disabling them. Further, the ack function only clears the interrupt if interrupts are enabled.

* phy: Fix phy_id for Vitesse 824x PHYKumar Gala2007-06-281-1/+1
| | | | | | | | | | The phy_id specified for the Vitesse 824x PHY would never match because it was expecting bits to be set that would be masked by the phy_id_mask.
