[PATCH] 2.6.18: sb1250-mac: Broadcom PHY support This patch adds support for interrupt-driven operation of the Broadcom Gigabit Ethernet PHYs. I have included device IDs for the parts used on Broadcom SiByte evaluation boards; more can be added as a need arises. They are apparently generally software-compatible with one another.

tg3 / broadcom: Add code to disable rxc refclk The 5785 does not use the RXC reference clock. Turning it off is desirable as it saves power. By default, the 50610 enables the RXC reference clock and the 50610M disables it. Presumably this is one of the reasons why the hardware architect chose one over the other. Adding a "rx reference clock disable" flag is not the ideal way to describe the option, as it would force the MAC using a 50610M to set the flag. Ideally we want the flags to represent opt-in behavior that deviates from hardware defaults. Furthermore, the lack of a "disable" flag implies that the requester wants the rx reference clock enabled, which doesn't necessarily follow. By presenting the option as a passive statement (rx reference clock unused) rather than a command, I hope to convey an opt-in option to disable the rx reference clock that falls back to hardware defaults if not set. A secondary benefit of this is that it keeps the intelligence about phy defaults in the broadcom module where it belongs and allows the broadcom module more latitude should a bug arise.

net: phy: broadcom: rehook BCM54612E specific init This extra BCM54612E code in PHY driver isn't really aneg specific. Even without it aneg works OK but the problem is no packets pass through PHY. Moreover putting this code inside config_aneg callback didn't allow resuming PHY correctly. When driver called phy_stop and phy_start it was putting PHY machine into RESUMING state. After that machine was switching into AN and NOLINK without ever calling phy_start_aneg. This prevented this extra setup from being called and PHY didn't work. This change has been verified to fix network on BCM47186B0 SoC device with BCM54612E.

tg3 / broadcom: Add code to disable rxc refclk The 5785 does not use the RXC reference clock. Turning it off is desirable as it saves power. By default, the 50610 enables the RXC reference clock and the 50610M disables it. Presumably this is one of the reasons why the hardware architect chose one over the other. Adding a "rx reference clock disable" flag is not the ideal way to describe the option, as it would force the MAC using a 50610M to set the flag. Ideally we want the flags to represent opt-in behavior that deviates from hardware defaults. Furthermore, the lack of a "disable" flag implies that the requester wants the rx reference clock enabled, which doesn't necessarily follow. By presenting the option as a passive statement (rx reference clock unused) rather than a command, I hope to convey an opt-in option to disable the rx reference clock that falls back to hardware defaults if not set. A secondary benefit of this is that it keeps the intelligence about phy defaults in the broadcom module where it belongs and allows the broadcom module more latitude should a bug arise.

tg3 / broadcom: Add code to disable rxc refclk The 5785 does not use the RXC reference clock. Turning it off is desirable as it saves power. By default, the 50610 enables the RXC reference clock and the 50610M disables it. Presumably this is one of the reasons why the hardware architect chose one over the other. Adding a "rx reference clock disable" flag is not the ideal way to describe the option, as it would force the MAC using a 50610M to set the flag. Ideally we want the flags to represent opt-in behavior that deviates from hardware defaults. Furthermore, the lack of a "disable" flag implies that the requester wants the rx reference clock enabled, which doesn't necessarily follow. By presenting the option as a passive statement (rx reference clock unused) rather than a command, I hope to convey an opt-in option to disable the rx reference clock that falls back to hardware defaults if not set. A secondary benefit of this is that it keeps the intelligence about phy defaults in the broadcom module where it belongs and allows the broadcom module more latitude should a bug arise.

Moreover putting this code inside config_aneg callback didn't allow resuming PHY correctly. When driver called phy_stop and phy_start it was putting PHY machine into RESUMING state. After that machine was switching into AN and NOLINK without ever calling phy_start_aneg. This prevented this extra setup from being called and PHY didn't work.

I've kept the magic numbers, so we'll not forget to fix it at the first opportunity, and will name that register and its bits correctly. p.s. also fixed the line with broken indention, introduced by commit 03157ac31eb4a8883382a212b161d2e6c5059fbf PHYLIB: Add BCM5482 PHY support Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

net: phy: Allow BCM5481x PHYs to setup internal TX/RX clock delay This patch allows users to enable/disable internal TX and/or RX clock delay for BCM5481x series PHYs so as to satisfy RGMII timing specifications. On a particular platform, whether TX and/or RX clock delay is required depends on how PHY connected to the MAC IP. This requirement can be specified through "phy-mode" property in the platform device tree.

Also, some users of the BCM54810 require the PHY lanes to be swapped. Since there is no way to detect this, add a device tree query to see if it is applicable.

This commit also effectively reverts the recently applied c7a61319 ("net: phy: dp83848: Support ethernet pause frames"). So the new process is: 1) Unless the PHY driver overrides it, phylib sets the SUPPORTED_Pause and SUPPORTED_AsymPause bits in phydev->supported. This indicates that the PHY supports pause frames. 2) The MAC driver checks phydev->supported before it calls phy_start(). If (SUPPORTED_Pause | SUPPORTED_AsymPause) is set, then the MAC driver sets those bits in phydev->advertising, if it wants to enable pause frame support. 3) When the link state changes, the MAC driver checks phydev->pause and phydev->asym_pause, If the bits are set, then it enables the corresponding features in the MAC. The algorithm is: if (phydev->pause) The MAC should be programmed to receive and honor pause frames it receives, i.e. enable receive flow control. if (phydev->pause != phydev->asym_pause) The MAC should be programmed to transmit pause frames when needed, i.e. enable transmit flow control.

Moreover putting this code inside config_aneg callback didn't allow resuming PHY correctly. When driver called phy_stop and phy_start it was putting PHY machine into RESUMING state. After that machine was switching into AN and NOLINK without ever calling phy_start_aneg. This prevented this extra setup from being called and PHY didn't work.

net: phy: phy drivers should not set SUPPORTED_[Asym_]Pause Instead of having individual PHY drivers set the SUPPORTED_Pause and SUPPORTED_Asym_Pause flags, phylib itself should set those flags, unless there is a hardware erratum or other special case. During autonegotiation, the PHYs will determine whether to enable pause frame support. Pause frames are a feature that is supported by the MAC. It is the MAC that generates the frames and that processes them. The PHY can only be configured to allow them to pass through. This commit also effectively reverts the recently applied c7a61319 ("net: phy: dp83848: Support ethernet pause frames"). So the new process is: 1) Unless the PHY driver overrides it, phylib sets the SUPPORTED_Pause and SUPPORTED_AsymPause bits in phydev->supported. This indicates that the PHY supports pause frames. 2) The MAC driver checks phydev->supported before it calls phy_start(). If (SUPPORTED_Pause | SUPPORTED_AsymPause) is set, then the MAC driver sets those bits in phydev->advertising, if it wants to enable pause frame support. 3) When the link state changes, the MAC driver checks phydev->pause and phydev->asym_pause, If the bits are set, then it enables the corresponding features in the MAC. The algorithm is: if (phydev->pause) The MAC should be programmed to receive and honor pause frames it receives, i.e. enable receive flow control. if (phydev->pause != phydev->asym_pause) The MAC should be programmed to transmit pause frames when needed, i.e. enable transmit flow control.

So the new process is: 1) Unless the PHY driver overrides it, phylib sets the SUPPORTED_Pause and SUPPORTED_AsymPause bits in phydev->supported. This indicates that the PHY supports pause frames. 2) The MAC driver checks phydev->supported before it calls phy_start(). If (SUPPORTED_Pause | SUPPORTED_AsymPause) is set, then the MAC driver sets those bits in phydev->advertising, if it wants to enable pause frame support. 3) When the link state changes, the MAC driver checks phydev->pause and phydev->asym_pause, If the bits are set, then it enables the corresponding features in the MAC. The algorithm is: if (phydev->pause) The MAC should be programmed to receive and honor pause frames it receives, i.e. enable receive flow control. if (phydev->pause != phydev->asym_pause) The MAC should be programmed to transmit pause frames when needed, i.e. enable transmit flow control.
