net: documentation: build a directory structure for drivers

2018-12-05T19:30:06+00:00

Documentation/networking/ is full of cryptically named files with driver documentation. This makes finding interesting information at a glance really hard. Move all those files into a directory called device_drivers (since not all drivers are for device) and fix up references. RFC v0.1 -> RFC v1: - also add .txt suffix to the files which are missing it (Quentin) Signed-off-by: Jakub Kicinski Reviewed-by: Quentin Monnet Acked-by: David Ahern Acked-by: Henrik Austad Signed-off-by: David S.

net: smmac: allow configuring lower pbl values

2016-12-08T18:07:10+00:00

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

2016-12-08T18:07:10+00:00

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.

drivers: net: stmmac: reworking the PCS code.

2016-06-28T12:54:23+00:00

The 3.xx and 4.xx synopsys gmacs have a very similar PCS embedded module and they share almost the same registers: for example: AN_Control, AN_Status, AN_Advertisement, AN_Link_Partner_Ability, AN_Expansion, TBI_Extended_Status. Just the RGMII/SMII Control/Status register differs. So This patch aims to reorganize and enhance the PCS support. It removes the existent support from the dwmac1000/dwmac4_core.c moving basic PCS functions inside a new file called: stmmac_pcs.h. The patch also reviews the available APIs to be better shared among different hardware and easily enhanced to support new features. Signed-off-by: Giuseppe Cavallaro Signed-off-by: David S. Miller

phy: fixed_phy: Add gpio to determine link up/down.

2015-08-31T21:48:02+00:00

An SFP module may have a link up/down status pin which can be connection to a GPIO line of the host. Add support for reading such an GPIO in the fixed_phy driver. Signed-off-by: Andrew Lunn Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

stmmac: remove setup/free glue callbacks

2015-07-29T07:13:25+00:00

As all dwmac-* drivers have been converted to have a proper probe function the setup callback can now be removed. Also remove the free callback that wasn't used by any driver. New dwmac-* drivers should implement standard probe and remove functions to preform any needed setup and teardown. Signed-off-by: Joachim Eastwood Signed-off-by: David S. Miller

stmmac: remove unused stmmac_of_data struct

2015-07-29T07:13:24+00:00

As dwmac-* drivers that need OF match have been converted to use their own internal OF match data structure this can now be removed. Signed-off-by: Joachim Eastwood Signed-off-by: David S. Miller

stmmac: drop custom_* fields from plat_stmmacenet_data

2015-07-21T03:45:57+00:00

Both of these fields are unused and has been unused since they were added 3 and 5 years ago. Drop them since they are clearly not very useful. Signed-off-by: Joachim Eastwood Signed-off-by: David S. Miller
