When VPHN function is not supported and during cpu hotplug event,
kernel prints message 'VPHN function not supported. Disabling
polling...'. Currently it prints on every hotplug event, it floods
dmesg when a KVM guest tries to hotplug huge number of vcpus, let's
just print once and suppress further kernel prints.

Some i.MX SoCs contain a system controller that is responsible for
controlling the state of the IPs that are present. Communication
between the host processor running an OS and the system controller
happens through a SCU protocol. This patch adds SCU protocol based

I think I'm probably the one who argued in favor of having separate
implementations for both PCHs, but the calculations are actually the
same, the clocks are the same and the only difference is that on ICP
we write the numerator to the register.
I have previously suggested to kill cnp_rawclk() and keep the
icp_rawclk() style, but Ville gave some good arguments that what's in
this patch may be the better choice.
v2: Switch numerator to 1 from 1000 and adjust calculations
accordingly (Ville).

Although CNP names this field "Counter Fraction", what we write to the
register is really the denominator for the fractional part of the
divider, not the fractional part (and the field description even says
that). The ICP spec renamed the field to "Counter Fraction
Denominator", which makes a lot more sense. Use the more complete ICL
naming because we will merge the CNP and ICP functions into a single
one, which will introduce the concept of the numerator. That will make
a lot more sense when you read the "num/frac = den" calculation.

In the initial commit [1], I added differential output of the codec as
separate `+` and `-` widgets:
OUTL+
OUTR+
OUTL-
OUTR-
Later, in the commit [2], I added a device tree property to configure the
output as single-ended or differential. Having this property, the `+` and
`-` separation in widgets seems for me confusing. There are no functional
benefits in such separation, so I find reasonable to get rid of it:
OUTL
OUTR
The new naming is more friendly for sound cards, and is better aligned with
other codec drivers in kernel.
Renaming the output widgets now should not be a problem from the backwards-
compatibility perspective, as the driver for PCM3060 is added into the
mainline very recently, and did not yet appear in any releases.

Each slave has it's own receive timestamp filter. But cpts rx/tx
timestamp enable flags are used to allow ts retrieve only for one
user. This limitation causes data path redundancy and setting overlap
if cpsw module is in dual-mac mode for instance.
If rx ts is enabled only for one port - the second interface must expect
every incoming packet to be PTP packet w/o absolutely any reason, and if
it's PTP - do unneeded stuff, as rx filter for second port is not set
and cpts fifo is not supposed to contain appropriate ts event.
That's not correct.
So, to fix control overlap and avoid redundant CPU cycles, the patch
splits rx/tx ts enable flags between network devices. After the patch,
PTP timestamping still should be used for only one port (or PTP id
counter has to be different for both ports as cpts IP is common).

- if they have been controlled by SW.
- if state transition from poweroff is done to SNVS
BD71837 can after reset transition from power-off to SNVS or
READY state depending on reset reason. By default only wathcdog
reset changes state from poweroff to ready. Change PMIC
configuration to always transition to READY in order to avoid
crucial power rails being OFF after reset.
If SNVS is required the crucial power rails should not be
controlled by SW - eg corresponding regulator control register
should have SEL bit kept zero. Currently the driver assumes all
regulators to be controlled by SW so it sets all SEL bits to 1.

MAX8997 driver disables automatic path selection from MicroUSB connector
and manually sets path to either UART or USB lines. However the code for

to ground). When standard USB cable (USB device mode) is connected, path
registers are not touched. This means that once the non-USB accessory is
connected to MAX8997-operated micro USB port, the path is no longer set
to USB and USB device mode doesn't work. This patch fixes it by setting
USB path both for USB and USB host modes.
