2018-10-12T11:41:24+00:00

We need to #ifdef some variables to avoid warning about them being
unused.

driver: net: fsl-mc: Add support of multiple phys for dpmac

2018-10-10T17:45:28+00:00

Till now we have had cases where we had one phy device per dpmac.
Now, with the upcoming products (LX2160AQDS), we have cases, where there
are sometimes two phy devices for one dpmac. One phy for TX lanes and
one phy for RX lanes. to handle such cases, add the support for multiple
phys in ethernet driver. The ethernet link is up if all the phy devices
connected to one dpmac report link up. also the link capabilities are
limited by the weakest phy device.

i.e. say if there are two phys for one dpmac. one operates at 10G without
autoneg and other operate at 1G with autoneg. Then the ethernet interface
will operate at 1G without autoneg.

driver: net: fsl-mc: Modify the dpmac link detection method

2018-10-10T17:45:01+00:00

when there is no phy present for a dpmac, a dummy phy device is created.
when we move to multiple phy method, we need to create as many dummy phy
devices.

Change this method so that we don't need to create dummy phy devices.
We always report linkup if no phy is present.

driver: net: fsl-mc: fix error handing in init_phy

2018-10-10T17:43:18+00:00

if an error occurs during init_phy, we should free the phydev structure
which has been allocated by phy_connect.

driver: net: fsl-mc: remove unused strcture elements

2018-10-10T17:36:34+00:00

The phydev structure is present in both ldpaa_eth_priv and
wriop_dpmac_info. the phydev in wriop_dpmac_info is not being used

As the phydev is created based on phy_addr and bus members of
wriop_dpmac_info, it is appropriate to keep phydev in wriop_dpmac_info.

Also phy_regs is not being used, therefore remove it

fsl/mc: Limit the ethernet name to ETH_NAME_LEN

2018-08-08T15:23:49+00:00

The ethernet name should be within the ETH_NAME_LEN, as this
is the buffer space allocated to ethernet name.

Otherwise, this causes buffer overflow.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

driver: net: fsl-mc: flib changes for MC 10.3.0

2017-12-06T22:55:17+00:00

Existing MC driver framework is based on MC-9.x.x flib. This patch
migrates MC obj (DPBP, DPNI, DPRC, DPMAC etc) to use latest MC flib
which is MC-10.3.0.

Changes introduced due to migration:
1. To get OBJ token, pair of create and open API replaces create APIs
2. Pair of close and destroy APIs replaces destroy APIs
3. For version read, get_version APIs replaces get_attributes APIs
4. dpni_get/reset_statistics APIs replaces dpni_get/set_counter APIs
5. Simplifies struct dpni_cfg and removes dpni_extended_cfg struct
6. Single API dpni_get_buffer_layout/set_buffer_layout replaces
   dpni_get_rx/set_rx, tx related, tx_conf_buffer_layout related APIs.
   New API takes a queue type as an argument.
7. Similarly dpni_get_queue/set_queue replaces
   dpni_get_rx_flow/set_rx_flow , tx_flow related, tx_conf related
   APIs
