This adds support for an external phy connected to the mac controlled by b44. This is used on home routers of the BCM47xx line where this MAC core was used and is contended to an external switch core through MII. These patches are in OpenWrt for some time and are tested by different users with different devices. The publicly available Programmer's Reference Guide for some of these chips help making this patch it would be nice to have such a documentation for more Broadcom Chips like some SoCs. https://www.broadcom.com/collateral/pg/440X-PG02-R.pdf v3: - remove changes to the fixed phy driver - call fixed_phy_add() in arch/mips/bcm47xx/setup.c before the fixed phy gets registered v2: - add fixed phy driver patch - use fixed phy driver in b44 - some smaller changes and typos Hauke Mehrtens (8): b44: check register instead of PHY address to detect external PHY b44: rename B44_PHY_ADDR_NO_PHY to B44_PHY_ADDR_NO_LOCAL_PHY b44: abort when no PHY is available at all b44: rename b44_mii_{read,write} to b44_mdio_{read,write}_mii b44: add phylib support b44: activate PHY when MAC is off b44: do not set PHY address to 30 for every ext PHY b44: use fixed PHY device if we do not find any arch/mips/bcm47xx/setup.c | 10 ++ drivers/net/ethernet/broadcom/Kconfig | 1 + drivers/net/ethernet/broadcom/b44.c | 250 ++++++++++++++++++++++++++++++--- drivers/net/ethernet/broadcom/b44.h | 15 +- 4 files changed, 250 insertions(+), 26 deletions(-) -- 1.7.10.4
