net: smmac: allow configuring lower pbl values

2016-12-08T18:07:10Z

The driver currently always sets the PBLx8/PBLx4 bit, which means that the pbl values configured via the pbl/txpbl/rxpbl DT properties are always multiplied by 8/4 in the hardware. In order to allow the DT to configure lower pbl values, while at the same time not changing behavior of any existing device trees using the pbl/txpbl/rxpbl settings, add a property to disable the multiplication of the pbl by 8/4 in the hardware.

net: stmmac: add support for independent DMA pbl for tx/rx

2016-12-08T18:07:10Z

GMAC and newer supports independent programmable burst lengths for DMA tx/rx. Add new optional devicetree properties representing this. To be backwards compatible, snps,pbl will still be valid, but snps,txpbl/snps,rxpbl will override the value in snps,pbl if set. If the IP is synthesized to use the AXI interface, there is a register and a matching DT property inside the optional stmmac-axi-config DT node for controlling burst lengths, named snps,blen. However, using this register, it is not possible to control tx and rx independently. Also, this register is not available if the IP was synthesized with, e.g., the AHB interface.

Revert "net: stmmac: allow to split suspend/resume from init/exit callbacks"

2016-11-09T18:21:25Z

Instead of adding hooks inside stmmac_platform it is better to just use the standard PM callbacks within the specific dwmac-driver. This only used by the dwmac-rk driver.

drivers: net: stmmac: add port selection programming

2016-06-28T12:54:23Z

In case of SGMII more, for example when a MAC2MAC connection is needed, the port selection bits (inside the MAC configuration registers) have to be programmed according to the link selected. So the patch adds a new DT parameter to pass the port selection and to programmed related PCS and CORE to use it. Signed-off-by: Giuseppe Cavallaro Signed-off-by: David S. Miller

net: stmmac: allow to split suspend/resume from init/exit callbacks

2016-06-16T21:14:58Z

Let the stmmac platform drivers provide dedicated suspend and resume callbacks rather than always re-using the init and exits callbacks. If the driver does not provide the suspend or resume callback, we fall back to the old behavior trying to use exit or init. This allows a specific platform to perform only a partial power-down on suspend if Wake-on-Lan is enabled but always perform the full shutdown sequence if the module is unloaded.

stmmac: fix MDIO settings

2016-04-01T18:38:59Z

Initially the phy_bus_name was added to manipulate the driver name but it was recently just used to manage the fixed-link and then to take some decision at run-time. So the patch uses the is_pseudo_fixed_link and removes the phy_bus_name variable not necessary anymore. The driver can manage the mdio registration by using phy-handle, dwmac-mdio and own parameter e.g. snps,phy-addr. This patch takes care about all these possible configurations and fixes the mdio registration in case of there is a real transceiver or a switch (that needs to be managed by using fixed-link).

This reverts commit 88f8b1bb41c6208f81b6a480244533ded7b59493. due to problems on GeekBox and Banana Pi M1 board when connected to a real transceiver instead of a switch via fixed-link.

stmmac: Fix 'eth0: No PHY found' regression

2016-03-03T20:02:05Z

This patch manages the case when you have an Ethernet MAC with a "fixed link", and not connected to a normal MDIO-managed PHY device. The test of phy_bus_name was not helpful because it was never affected and replaced by the mdio test node. Signed-off-by: Gabriel Fernandez Acked-by: Giuseppe Cavallaro Signed-off-by: David S. Miller
