      Each independent example should be a separate entry. This allows for

      dt-bindings: display: Add SPI peripheral schema to SPI based displays · c476d430
      Rob Herring authored 
      With 'unevaluatedProperties' support enabled, several SPI based display
binding examples have warnings:

Fix all of these by adding a reference to spi-peripheral-props.yaml.
With this, the description that the binding must follow
spi-controller.yaml is both a bit out of date and redundant, so remove
it.

      dt-bindings: net: snps,dwmac: Enable burst length properties for more compatibles · 1d01efaf
      Rob Herring authored 
      With 'unevaluatedProperties' support implemented, the properties
'snps,pbl', 'snps,txpbl', and 'snps,rxpbl' are not allowed in the
examples for some of the DWMAC versions:

Documentation/devicetree/bindings/net/intel,dwmac-plat.example.dt.yaml: ethernet@3a000000: Unevaluated properties are not allowed ('snps,pbl', 'mdio0' were unexpected)

This appears to be an oversight, so fix it by allowing the properties
on the v3.50a, v4.10a, and v4.20a versions of the DWMAC.

      An MDIO bus can have devices other than ethernet PHYs on it, so it
should allow for any node name rather than just 'ethernet-phy'.

      of/fdt: Don't worry about non-memory region overlap for no-map · da17d690
      Stephen Boyd authored 
      In commit 8a5a75e5 ("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: base: Improve argument length mismatch error · 5d05b811
      Baruch Siach authored 
      The cells_name field of of_phandle_iterator might be NULL. Use the
phandle name instead. With this change instead of:

  OF: /soc/pinctrl@1000000: (null) = 3 found 2

We get:

  OF: /soc/pinctrl@1000000: phandle pinctrl@1000000 needs 3, found 2

Which is a more helpful messages making DT debugging easier.

In this particular example the phandle name looks like duplicate of the
same node name. But note that the first node is the parent node
(it->parent), while the second is the phandle target (it->node). They
happen to be the same in the case that triggered this improvement. See
commit 72cb4c48 ("arm64: dts: qcom: ipq6018: Fix gpio-ranges
property").
