2014-01-04bgmac: add support for Northstar SoC (BCM4707, BCM53018)Hauke Mehrtens1-0/+1
This adds support for the Northstar SoC. This SoC does not have a PMU in bcma and no register on it should be called. In addition it support 2.5 GBit/s Ethernet to the PHY. This GMAC core is not fully working there are still problems with the DMA controller. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-01-04bgmac: add support for new BGMAC_CMDCFG_SR position on core rev >= 4Hauke Mehrtens1-1/+3
The BGMAC_CMDCFG_SR register is at a different position on core rev >= 4 We do not know where this register is on a rev 5 or higher core, I have newer seen such a core.

2014-01-04bgmac: initialize the DMA controller of core rev >= 4Hauke Mehrtens1-0/+50
The DMA controller used in the device supported by GMAC with core rev >= 4 has some new options which are now set to the default values used in the Broadcom SDK.

2013-12-09bgmac: connect to PHY and make use of PHY deviceRafał Miłecki1-8/+4
We were already registering MDIO bus, but we were not connecting bgmac to the PHY. Add proper call and implement adjust link function to switch MAC into requested state. At the same time it's possible to drop our internal PHY management. This is a "standard" PHY, so the "Generic PHY" driver works perfectly fine with this. Don't duplicate the code. Finally make use of phy_ethtool_[gs]set functions instead implementing them from scratch. This change was successfully tested on BCM5357. I was able to autonegotiate 1000Mb/s full duplex, as well as force any of the 10/100/1000 half/full modes.

2013-09-16bgmac: implement unaligned addressing for DMA rings that support itRafał Miłecki1-0/+2
This is important patch for new devices that support unaligned addressing. That devices suffer from the backward-compatibility bug in DMA engine. In theory we should be able to use old mechanism, but in practice DMA address seems to be randomly copied into status register when hardware reaches end of a ring. This breaks reading slot number from status register and we can't use DMA anymore. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-09-16bgmac: fix internal switch initializationRafał Miłecki1-1/+1
Some devices (BCM4749, BCM5357, BCM53572) have internal switch that requires initialization. We already have code for this, but because of the typo in code it was never working. This resulted in network not working for some routers and possibility of soft-bricking them. Use correct bit for switch initialization and fix typo in the define.

2013-02-13bgmac: return error on failed PHY writeRafał Miłecki1-3/+0
Some callers may want to know if PHY write succeed. Also make PHY functions static, they are not exported anywhere. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-01-09bgmac: driver for GBit MAC core on BCMA busRafał Miłecki1-0/+456
BCMA is a Broadcom specific bus with devices AKA cores. All recent BCMA based SoCs have gigabit ethernet provided by the GBit MAC core. This patch adds driver for such a cores registering itself as a netdev. It has been tested on a BCM4706 and BCM4718 chipsets. In the kernel tree there is already b44 driver which has some common things with bgmac, however there are many differences that has led to the decision or writing a new driver: 1) GBit MAC cores appear on BCMA bus (not SSB as in case of b44) 2) There is 64bit DMA engine which differs from 32bit one 3) There is no CAM (Content Addressable Memory) in GBit MAC 4) We have 4 TX queues on GBit MAC devices (instead of 1) 5) Many registers have different addresses/values 6) RX header flags are also different The driver in it's state is functional how, however there is of course place for improvements: 1) Supporting more net_device_ops 2) SUpporting more ethtool_ops 3) Unaligned addressing in DMA 4) Writing separated PHY driver Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: David S.
