LF-5352: dmaengine: imx-sdma: fix the potential access registers without clock

The issue can be triggered with the sdma pm_runtime false.

If the dma client try to use sdma in boot phase, it may cause
system hang. The sdma driver really enable clk after sdma load
firmware, the clk_disable_unused will disable the SDMA1_ROOT_CLK
before the sdma driver enable clk. This issue will comes if access
the sdma register when the SDMA1_ROOT_CLK is disable.

This issue is very easy to reproduce with hdmi connected displayer
on imx7d-sbd board which the i2c will use sdma early before sdma
firmware loaded and clock enabled.

The client i2c calls dmaengine_prep_slave_single->device_prep_slave_sg
->sdma_prep_slave_sg->sdma_config_write->sdma_config_channel to get
descriptor in boot phase. Then, the function sdma_config_channel will
access sdma registers. If clk is disable will cause system hang.

This patch adds clk_enable and clk_disable to make sure the clk
enable before access sdma hardware.

sdk_dpaa: rework private bpool seeding per CPU per interface

The dpa_bp introduction has modified the existing design of buffer
pool seeding. The most notable (and unintended) change was that
instead of placing in the buffer pool an allotment of buffers for
each CPU, for each interface, only an allotment for each CPU was
performed. With this, the possibility that in certain scenarios,
each interface can draw from the buffer pool enough buffers to
drain it completely, but not enough to trigger a refill. This may
result in a complete stall of the reception on the interface.

The current patch reintroduces the initial design, that makes sure
each probed interface contributes to the common buffer pool an
allotment of buffers for each CPU, removing the above mentioned
issue.

In consequence, the per buffer pool seed_cb() callback is removed.
The seeding is now done at net device probe.

Add the in-band configuration knob for the VSC8514 quad PHY. Tested with

net: phylink: explicitly configure in-band autoneg for PHYs that support it

Currently Linux has no control over whether a MAC-to-PHY interface uses
in-band signaling or not, even though phylink has the
managed = "in-band-status";
property which denotes that the MAC expects in-band signaling to be used.

The problem is really that if the in-band signaling is configurable in
both the PHY and the MAC, there is a risk that they are out of sync
unless phylink manages them both. Most if not all in-band autoneg state
machines follow IEEE 802.3 clause 37, which means that they will not
change the operating mode of the SERDES lane from control to data mode
unless in-band AN completed successfully. Therefore traffic will not
work.

It is particularly unpleasant that currently, we assume that PHYs which
have configurable in-band AN come pre-configured from a prior boot stage
such as U-Boot, because once the bootloader changes, all bets are off.

Let's introduce a new PHY driver method for configuring in-band autoneg,
and make phylink be its first user. The main PHY library does not call
phy_config_inband_autoneg, because it does not know what to configure it
to. Presumably, non-phylink drivers can also call phy_config_inband_autoneg
individually.

sdk_dpaa: memac: fix AQR autoneg to lower than 10G partners

Stop removing unsupported system side modes with AQR PHYs. Originally,
their removal didn't impact the modes advertised by the PHY. Since
auto-negotiation support was added to the aquantia driver, the
unsupported modes were no longer advertised. This prohibited the
PHY from negotiating with 1G link partners on LS1046ARDB.

Patch adapted from similar fix for the upstream DPAA1 Ethernet driver:
commit fddb5a50801a ("dpaa_eth: support all modes with rate adapting PHYs")

Aquantia auto-negotiation:

configuration")
