1a048cd656 driver: net: fsl-mc: Add support of multiple phys for dpmac
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.

a3cb5340f1 driver: net: fsl-mc: Modify the dpmac link detection method
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.

d75e81d9e0 driver: net: fsl-mc: remove unused strcture elements
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

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.

2557c5a942 driver: net: fsl-mc: flib changes for MC 10.3.0
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

5753b0f1b0 driver/ldpaa_eth: Update ldpaa ethernet driver
Fix flush_dcache_range() input parameter to use start and end addresses.
Change ethernet interface name to DPNI. Update entry criteria for
ldpaa_eth_stop. Ethernet stack first stop the device before performing
next operation. At the time of Ethernet driver registration,
net_dev->state is set as ETH_STATE_INIT So take care net_dev->state as
ETH_STATE_INIT in ldpaa_eth_stop.

Undef CONFIG_PHYLIB temorarily because ldpaa_eth driver currently does
not support PHYLIB.

Instead of clearing pull descriptor one time, clear it before issuing any
volatile dequeue command.

Volatile command does not return frame immidiately, wait till a frame
is available in DQRR. This frame can be valid or expired.

Flush buffer before releasing to BMan ensure the core does not have any
cachelines that the WRIOP will DMA to.
