d88bcd6d24 net: dwc_eth_qos: Remove obsolete imx8 includes
They were added with commit 0e9d23945c ("net: eqos: implement callbaks
to get interface and set txclk rate") but were not removed with
commit 5fc783b5d9 ("net: dwc_eth_qos: move i.MX code out") when i.MX
specific code was moved to a separate file.

669e628d44 net: dwc_eth_qos: Add support for platform specific reset
This patch adds support for optional platform specific reset logic in
the dwc_eth_qos driver. This new function 'eqos_fix_soc_reset' is called
after the EQOS_DMA_MODE_SWR is set and before the driver waits for this
bit to clear.

beabef6511 net: dwc_eth_qos: Adapt probe() for PCI devices
PCI devices do not necessarily use a device tree. In that case, the
driver currently fails to find eqos->config and eqos->regs.

This commit factors out the respective functionality. Device tree usage

Bevor this commit, only clause 22 access was possible. After this commit,
clause 45 direct access will available as well.

Note that there is a slight change of behavior: Before this commit, the
C45E bit was set to whatever value was left in the register from the
previous access. After this commit, we adopt the common practice of
discerning C45 from C22 using the devad argument.

a79de0808a net: dwc_eth_qos: Set DMA_MODE SWR bit to reset the MAC
The driver currently only waits for DMA_MODE SWR bit to clear itself.
This is insufficient e.g. on i.MX8M Plus, where the MAC must be reset
before IOMUX GPR[1] content is latched into the MAC and used. Without
the proper reset, the i.MX8M Plus MAC variant does not take the value
in IOMUX GPR[1] into account, which makes it impossible e.g. to switch
interface mode from RGMII to any other.

Since proper reset is desired in general to put the block into defined
state, always assert the DMA_MODE SWR bit before waiting for the bit
to clear itself.

e9d3fc7e46 net: dwc_eth_qos: Add support for bulk RX descriptor cleaning
Add new desc_per_cacheline property which lets a platform run RX descriptor
cleanup after every power-of-2 - 1 received packets instead of every packet.
This is useful on platforms where (axi_bus_width EQOS_AXI_WIDTH_n * DMA DSL
inter-descriptor word skip count + DMA descriptor size) is less than cache
line size, which necessitates packing multiple DMA descriptors into single
cache line.

In case of TX descriptors, this is not a problem, since the driver always
does synchronous TX, i.e. the TX descriptor is always written, flushed and
polled for completion in eqos_send().

In case of RX descriptors, it is necessary to update their status in bulk,
i.e. after the entire cache line worth of RX descriptors has been used up
to receive data.

c62b74652a net: dwc_eth_qos: remove use of DWC_NET_PHYADDR
Only two boards in the tree set the macro DWC_NET_PHYADDR. Both have
CONFIG_DM_ETH_PHY=y, so should set the phy address in DT if necessary.

The imx8mp_evk does set the correct address in device tree.

The other board seems to be a copy-paste-adapt from an old
version of the imx8mp_evk config header, given the "#ifdef
CONFIG_DWC_ETH_QOS" block that has been removed from imx8mp_evk header
in commit 127fb45495. Its device tree doesn't even enable (i.e., set
'status = "okay"') the &eqos node. But the other ethernet device,
&fec, does get enabled, and does have a phy sitting at address 4 (and
it also has a corresponding legacy #define CONFIG_FEC_MXC_PHYADDR
4). So I believe it should be completely safe to remove it from there
as well.

123ca114e0 net: introduce helpers to get PHY interface mode from a device/ofnode
Add helpers ofnode_read_phy_mode() and dev_read_phy_mode() to parse the
"phy-mode" / "phy-connection-type" property. Add corresponding UT test.

Use them treewide.

This allows us to inline the phy_get_interface_by_name() into
ofnode_read_phy_mode(), since the former is not used anymore.
