2011-12-16net/macb: add DT support for Cadence macb/gem driverJean-Christophe PLAGNIOL-VILLARD1-0/+2
Allow the device tree to provide the mac address and the phy mode. Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> [nicolas.ferre@atmel.com: change "compatible" node property, doc and DT hwaddr] Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com> [jamie@jamieiles.com: add "gem" compatibility strings and doc] Acked-by: Jamie Iles<jamie@jamieiles.com> Acked-by: David S. Miller <davem@davemloft.net>
2011-11-22macb: allow GEM to have configurable receive buffer sizeJamie Iles1-0/+5
GEM has configurable receive buffer sizes so requires this to be programmed up. Any size < 2048 and a multiple of 64 bytes is permitted.

2011-11-22macb: support DMA bus widths > 32 bitsJamie Iles1-0/+19
Some GEM implementations may support DMA bus widths up to 128 bits. We can get the maximum supported DMA bus width from the design configuration register so use that to program the device up.

2011-11-22macb: support statistics for GEM devicesJamie Iles1-1/+53
GEM devices have a different number of statistics registers and they are at a different offset to MACB devices. Make the statistics collection method dependent on device type.

2011-11-22macb: support higher rate GEM MDIO clock divisorsJamie Iles1-0/+11
GEM devices support larger clock divisors and have a different range of divisors. Program the MDIO clock divisors based on the device type.

2011-11-22macb: initial support for Cadence GEMJamie Iles1-0/+61
The Cadence GEM is based on the MACB Ethernet controller but has a few small changes with regards to register and bitfield placement. This patch detects the presence of a GEM by reading the module ID register and setting a flag appropriately. This handles the new HW address, USRIO and hash register base register locations in GEM. v3: - convert to macb_is_gem() inline rather than storing a boolean flag - handle rx_overrun stats for gem Acked-by: David S.

Move the Atmel driver into drivers/net/ethernet/cadence/ and make the necessary Kconfig and Makefile changes.
