2014-09-28net: dsa: bcm_sf2: add support for controlling EEEFlorian Fainelli1-0/+73
When EEE is enabled, negotiate this feature with the PHY and make sure that the capability checking, local EEE advertisement, link partner EEE advertisement and auto-negotiation resolution returned by phy_init_eee() is positive, and enable EEE at the switch level. While querying the current EEE settings, verify the low-power indication and indicate its status. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

2014-09-28net: dsa: bcm_sf2: add port_enable/disable callbacksFlorian Fainelli1-20/+40
The SF2 switch driver is already architected around per-port enable/disable callbacks, so we just need a slight update to our existing bcm_sf2_port_setup() resp. bcm_sf2_port_disable() functions to be suitable as callbacks for port_enable/port_disable. We need to shuffle a little the code that does the per-port VLAN configuration/isolation since ports can now be brought up/down separately, so we need to make sure that IMP (CPU, management) port is always included in that specific port setup.

2014-09-28net: dsa: bcm_sf2: disable RGMII interface(s) when link is downFlorian Fainelli1-0/+9
When the link is down, disable the RGMII interface to conserve as much power as possible. We re-enable the RGMII interface whenever the link is detected. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-09-22net: dsa: bcm_sf2: add support for Wake-on-LANFlorian Fainelli1-0/+58
In order for Wake-on-LAN to work properly, we query the parent network device Wake-on-LAN features and advertise those. Similarly, when configuring Wake-on-LAN on a per-port network interface, we make sure that we do not accept something the master network devices does not support. Finally, we need to maintain a bitmask of the ports enabled for Wake-on-LAN to prevent the suspend() callback from disabling a port that is used for waking up the system.

2014-09-22net: dsa: bcm_sf2: add suspend/resume callbacksFlorian Fainelli1-0/+85
Implement the suspend/resume callbacks for the Broadcom Starfighter 2 switch driver. Suspending the switch requires masking interrupts and shutting down ports. Resuming the switch requires a software reset since we do not know which power-sate we might be coming from, and re-enabling the physical ports that are used.

2014-09-19net: dsa: bcm_sf2: communicate integrated PHY revision to PHY driverFlorian Fainelli1-0/+16
The integrated BCM7xxx PHY contains no useful revision information in its MII_PHYSID2 bits 3:0, that information is instead contained in the SWITCH_REG_PHY_REVISION register. Read this register, store its value, and return it by implementing the dsa_switch::get_phy_flags() callback accordingly. The register layout is already matching what the BCM7xxx PHY driver is expecting to find. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-09-15dsa: Replace mii_bus with a generic host deviceAlexander Duyck1-1/+1
This change makes it so that instead of passing and storing a mii_bus we instead pass and store a host_dev. From there we can test to determine the exact type of device, and can verify it is the correct device for our switch. So for example it would be possible to pass a device pointer from a pci_dev and instead of checking for a PHY ID we could check for a vendor and/or device ID.

2014-09-13net: dsa: change tag_protocol to an enumFlorian Fainelli1-1/+1
Now that we introduced an additional multiplexing/demultiplexing layer with commit 3e8a72d1dae37 ("net: dsa: reduce number of protocol hooks") that lives within the DSA code, we no longer need to have a given switch driver tag_protocol be an actual ethertype value, instead, we can replace it with an enum: dsa_tag_protocol. Do this replacement in the drivers, which allows us to get rid of the cpu_to_be16()/htons() dance, and remove ETH_P_BRCMTAG since we do not need it anymore.

2014-08-27net: dsa: add Broadcom SF2 switch driverFlorian Fainelli1-0/+626
Add support for the Broadcom Starfigther 2 switch chip using a DSA driver. This switch driver supports the following features: - configuration of the external switch port interface: MII, RevMII, RGMII and RGMII_NO_ID are supported - support for the per-port MIB counters - support for link interrupts for special ports (e.g: MoCA) - powering up/down of switch memories to conserve power when ports are unused Finally, update the compatible property for the DSA core code to match our switch top-level compatible node.
