dt-bindings: clock: imx5: Drop clock consumer node from example

The example nodes have different sized interrupt cells which is not valid
given no interrupt-parent is specified. As provider examples don't need to
show the consumer side in the first place, just drop the consumer node.

dt-bindings: Drop required 'interrupt-parent'

'interrupt-parent' is never required as it can be in a parent node or a
parent node itself can be an interrupt provider. Where exactly it lives is
outside the scope of a binding schema.

of/fdt: Don't worry about non-memory region overlap for no-map

In commit 8a5a75e5e9e5 ("of/fdt: Make sure no-map does not remove
already reserved regions") we returned -EBUSY when trying to mark
regions as no-map when they intersect with reserved memory. The goal was
to find bad no-map reserved memory DT nodes that would unmap the kernel
text/data sections.

The problem is the reserved memory check will still trigger if the DT
has a /memreserve/ that completely subsumes the no-map memory carveouts
in the reserved memory node _and_ that region is also not part of the
memory reg property. For example in sc7180.dtsi we have the following
reserved-memory and memory node:

      memory@80000000 {
          /* We expect the bootloader to fill in the size */
          reg = <0 0x80000000 0 0>;
      };

      smem_mem: memory@80900000 {
              reg = <0x0 0x80900000 0x0 0x200000>;
              no-map;
      };

and the memreserve filled in by the bootloader is

      /memreserve/ 0x80800000 0x400000;

while the /memory node is transformed into

      memory@80000000 {
          /* The bootloader fills in the size, and adds another region */
          reg = <0 0x80000000 0 0x00800000>,
                <0 0x80c00000 0 0x7f200000>;
      };

The smem region is doubly reserved via /memreserve/ and by not being
part of the /memory reg property. This leads to the following warning
printed at boot.

 OF: fdt: Reserved memory: failed to reserve memory for node 'memory@80900000': base 0x0000000080900000, size 2 MiB

Otherwise nothing really goes wrong because the smem region is not going
to be mapped by the kernel's direct linear mapping given that it isn't
part of the memory node. Therefore, let's only consider this to be a
problem if we're trying to mark a region as no-map and it is actually
memory that we're intending to keep out of the kernel's direct mapping
but it's already been reserved.

of: unittest: re-implement overlay tracking

Some overlays are tracked when they are applied.  The tracked overlays
are later removed after the overlay tests are completed.  The old
implementation makes assumptions about the expected values for
overlay changeset id created by the overlay apply which result
in fragile code.  The new code removes the assumptions.

A symptom that exposes a problem with the tracking code is a
warning "UBSAN: shift-out-of-bounds in drivers/of/unittest.c:1933:36",
Kernel Version: 5.15-rc7, PPC-64, Talos II.  This results from variable

dt-bindings: arm,cci-400: Drop the PL330 from example

The PL330 was commented out because its binding wasn't converted to a
schema. With the binding converted, the example now needs several updates.
However, while it's possible that the PL330 has a 'cci-control-port', there
aren't any platforms upstream which do. So rather than allowing
'cci-control-port' in the PL330 binding, let's just drop the example.

dt-bindings: Only show unique unit address warning for enabled nodes

There are valid cases when two nodes can have the same address. For

to provide UART, SPI or I2C block, all of which having the same base
register address. But only one can be enabled at a time. That looks like
this:

    usi@138200c0 {
        serial@13820000 {
            status = "okay";
        };

        i2c@13820000 {
            status = "disabled";
        };
    };

When running "make dt_binding_check", it reports next warning:

    Warning (unique_unit_address):
    /example-0/usi@138200c0/serial@13820000:

    /example-0/usi@138200c0/i2c@13820000)

Disable "unique_unit_address" in DTC_FLAGS to suppress warnings like
that, but enable "unique_unit_address_if_enabled" warning, so that dtc
still reports a warning when two enabled nodes are having the same
address.

This allows a bootloader to change the number of available CPUs (for

of cores) without deleting the nodes altogether, which could require
additional fixups to avoid dangling phandle references.

Unknown status values (everything that is not "okay"/"ok", "disabled" or

meaning that the CPU can be enabled during boot.

dt-bindings: hwmon: add TI DC-DC converters

Few Texas Instruments DC-DC converters on PMBus like TPS544B20 do not
have bindings and are used only as hardware monitoring sensor.  These
devices are actually not trivial and can receive basic configuration
(e.g. power up mode, CNTL pin polarity, expected input voltage), however
devicetree support for configuration was never added.

Therefore in current state the devices are used only in read-only mode
and have trivial bindings, so document them to have basic dtschema
tests.

dt-bindings: thermal: Fix definition of cooling-maps contribution property

When converting the thermal-zones bindings to yaml the definition of the
contribution property changed. The intention is the same, an integer
value expressing a ratio of a sum on how much cooling is provided by the
device to the zone. But after the conversion the integer value is
limited to the range 0 to 100 and expressed as a percentage.

This is problematic for two reasons.

- This do not match how the binding is used. Out of the 18 files that
  make use of the property only two (ste-dbx5x0.dtsi and
  ste-hrefv60plus.dtsi) sets it at a value that satisfy the binding,
  100. The remaining 16 files set the value higher and fail to validate.

- Expressing the value as a percentage instead of a ratio of the sum is
  confusing as there is nothing to enforce the sum in the zone is not
  greater then 100.

This patch restore the pre yaml conversion description and removes the
value limitation allowing the usage of the bindings to validate.

of: property: fw_devlink: Fixup behaviour when 'node_not_dev' is set

In the struct supplier_bindings the member 'node_not_dev' is described as
"The consumer node containing the property is never a device.", but that is
inconsistent with the behaviour of the code in of_link_property(), as it
calls of_get_compat_node() that starts parsing for a compatible property
from the node it gets passed to it. The proper behaviour is to start at the
node's parent, so let's do that.

While at it, let's take the opportunity to update the description of the
'node_not_dev' flag, as to clarify its purpose.
