NC-SI (Network Controller Sideband Interface) is a protocol to manage a
sideband connection to a proper network interface, for example a BMC
(Baseboard Management Controller) sharing the NIC of the host system.
Probing and configuration occurs by communicating with the "remote" NIC
via NC-SI control frames (Ethernet header 0x88f8).
This implementation is roughly based on the upstream Linux
implementation[0], with a reduced feature set and an emphasis on getting
a link up as fast as possible rather than probing the full possible
topology of the bus.
The current phy model relies on the network being "up", sending NC-SI
command frames via net_send_packet() and receiving them from the
net_loop() loop (added in a following patch).

setup per hardware default. This does not influence the other
versions as this regulator isn't used there at all.

arm: dts: k3-j721e-r5-common-proc-board: Use unique names for dummy clocks
Update the dummy clock names to use unique identifiers. Otherwise the
previous node just gets overwitten by the next one with the same name.
This fixes eMMC boot not working on J721e-evm.

arm: K3: sysfw-loader: Add a config_pm_pre_callback()
System firmware does not guarantee that clocks going out of the device
will be stable during power management configuration. There are some
DCRC errors when SPL tries to get the next stage during eMMC boot after
sysfw pm configuration.
Therefore add a config_pm_pre_callback() to switch off the eMMC clock
before power management and restart it after it is done.

mmc: am654_sdhci: Implement workaround for card detect
The 4 bit MMC controllers have an internal debounce for the SDCD line
with a debounce delay of 1 second. Therefore, after clocks to the IP are
enabled, software has to wait for this time before it can power on the
controller.
Add a deferred_probe() callback which polls on sdcd for a maximum of 2 seconds
before switching on power to the controller or (in the case of no card)
returning a ENOMEDIUM. This pushes the 1 second wait time to when the
card is actually needed rather than at every probe() making sure that
users who don't insert an SD card in the slot don't have to wait such a
long time.
