Switch the imx_clk_pll14xx function to clk_hw based API, rename
accordingly and add a macro for clk based legacy. This allows us to
move closer to a clear split between consumer and provider clk APIs.

This is just to keep in line with the other i.MX clock drivers that are
clk_hw based. Plus, it makes more sense to be called hws since its type is
clk_hw not clk.

Replacing with macros all the clk based API helpers we reduce the code
duplication. The end goal is to get rid of all these macros when there
will be no more users of the clk based API, that is, when all the i.MX
clock provider drivers will be switched completely to the clk_hw based
API.
This is another step in moving away from the non clk_hw based API usage
throughout the i.MX clock drivers. The reason for doing that is to
have a clear split between the clock provider and the clock consumer API.

If the clk_hw based API returns an error, trying to return the clk from
hw will end up in a NULL pointer dereference. So adding the to_clk
checker and using it inside every clk based macro helper we handle that
case correctly.
This to_clk is also temporary and will go away along with the clk based
macro helpers once there is no user that need them anymore.

On imx8 the LPCG nodes map entire subsystems and overlap peripherals,
this means that using devm_platform_ioremap_resource will cause many
devices to fail to probe including serial ports.
Well-meaning but boot-breaking patches were posted multiple times so add

The clock drivers on imx8m series are registered as platform devices and
this opens the possibility of reloading the driver at runtime.
This doesn't actually work: clocks are never removed and attempting to
bind again results in registration errors and a crash. Almost all
devices depend on clocks anyway so rebinding is unlikely to ever be
useful
Fix this by explicitly suppressing bind attrs like several other
clock drivers.

The /2 divider between pll4_audio_div and pll4_post_div is not working
on imx6q. The frequency is not halved as reported by the clock tree
and measured on clko.
In the technical reference manual the divider was removed in revision 4.
It's also not listed in the imx6qp manual.
imx6dl manual mentions a divider for PLL4 and the according register
description. So keep the divider here.

DRAM frequency switches are executed in firmware and can change the
configuration of the DRAM PLL outside linux. Mark these CLKs with
CLK_GET_RATE_NOCACHE so we always read back the PLL config registers and
recalculate rates.
In current DRAM frequency tables on 8mm/8mn only the maximum frequency
uses the PLL so it's always configured in the same way. However reading
back the PLL configuration is the correct behavior and allows additional
setpoints in the future.

These clocks are only modified as part of DRAM frequency switches during
which DRAM itself is briefly inaccessible. The switch is performed with
a SMC call to by TF-A which runs from a SRAM area; upon returning to
linux several clocks bits are modified and we need to update them.
For rate bits an easy solution is to just mark with
CLK_GET_RATE_NOCACHE so that new rates are always read back from
registers.

The commit ef87f7da6b28 ("net: phy: dp83867: move dt parsing to probe")
causes regression on TI dra71x-evm and dra72x-evm, where DP83867 PHY is
used in "rgmii-id" mode - the networking stops working.
Unfortunately, it's not enough to just move DT parsing code to .probe() as
it depends on phydev->interface value, which is set to correct value abter
the .probe() is completed and before calling .config_init(). So, RGMII
configuration can't be loaded from DT.
To fix and issue
- move RGMII validation code to .config_init()
- parse RGMII parameters in dp83867_of_init(), but consider them as
optional.

We may have found a bug in the nxp/lpc_eth.c driver. The function
platform_set_drvdata() is called twice, the second time it is called,
in lpc_mii_init(), it overwrites the struct net_device which should be
at pdev->dev->driver_data with pldat->mii_bus. When trying to remove
the driver, in lpc_eth_drv_remove(), platform_get_drvdata() will
return the pldat->mii_bus pointer and try to use it as a struct
net_device pointer. This causes unregister_netdev to segfault and
generate a kernel BUG. Is this reproducible?

The EEE support has not been enabled on ENETC, but it may connect
to a PHY which supports EEE and advertises EEE by default, while
its link partner also advertises EEE. If this happens, the PHY enters
low power mode when the traffic rate is low and causes packet loss.
This patch disables EEE advertisement by default for any PHY that
ENETC connects to, to prevent the above unwanted outcome.

Few ti-sysc related fixes for v5.5 merge window
Just few minor changes that can be merged when suitable, but would
be good to have these in v5.5-rc1 to remove dependencies between branches
for more changes later on in v5.6:
- Add quirk handling for AESS (Audio Engine Sub System)
- We want to drop the useless gptimer option for omap4 as there are local
timers
- A minor error path handling improvment for sysc_child_add_named_clock()
that will make further patching a bit easier
* tag 'omap-for-v5.5/ti-sysc-late-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
bus: ti-sysc: Adjust exception handling in sysc_child_add_named_clock()
ARM: OMAP2+: Drop useless gptimer option for omap4
bus: ti-sysc: Add module enable quirk for audio AESS

Previously, when set VF VLAN with command "ip link set <pf name>
vf <vf id> vlan <vlan id>", the VF ID 0 is handled as PF incorrectly,
which should be the first VF. This patch fixes it.
