The commit 3eb619b2f7 ("scripts/dtc: Update to upstream version
v1.6.0-11-g9d7888cbf19c") updated dtc version which also contained DTC
commit
"81e0919a3e21 checks: Add interrupt provider test"
where reasons for this checking are mentioned as
"A missing #address-cells property is less critical, but creates
ambiguities when used in interrupt-map properties, so warn about this as
well now."
That's why add address-cells property to gic and gpio nodes to get rid of
this warning.

DT schema is checking tuples which should be properly separated. The patch
is doing this separation to avoid the following warning:
..yaml: axi: pcie@fd0e0000:ranges: [[33554432, 0, 3758096384, 0,
3758096384, 0, 268435456, 1124073472, 6, 0, 6, 0, 2, 0]] is not valid under
any of the given schemas (Possible causes of the failure):
...dt.yaml: axi: pcie@fd0e0000:ranges: True was expected
...dt.yaml: axi: pcie@fd0e0000:ranges:0: [33554432, 0, 3758096384, 0,
3758096384, 0, 268435456, 1124073472, 6, 0, 6, 0, 2, 0] is too long

The reason for this change is that after change from amba to axi U-Boot
started to show error like:
Unable to update property /axi/ethernet@ff0e0000:mac-address, err=FDT_ERR_NOTFOUND
Unable to update property /axi/ethernet@ff0e0000:local-mac-address, err=FDT_ERR_NOTFOUND
The reason is implementation in fdt_nodename_eq_() which is taken from dtc
to the kernel and to the U-Boot. Especially DTC commit d2a9da045897 ("libfdt:
Make unit address optional for finding nodes") which is in DTC from 2007.
The part of commit description is
" This is contrary to traditional OF-like finddevice() behaviour, which
allows the unit address to be omitted (which is useful when the device
name is unambiguous without the address)."
The kernel commit dfff9066e6 ("arm64: dts: zynqmp: Rename buses to be
align with simple-bus yaml") changed amba-apu/amba to axi@0/axi but
fdt_nodename_eq_() detects /axi/ as match for /axi@0/ because of commit
above.
That's why it easier to fix one DT inside the kernel by moving GIC node
from own bus to generic axi bus as is done by others SoCs. This will avoid
incorrect match because the unit address is omitted.

DT binding permits only one compatible string which was decribed in past by
commit 63cab195bf ("i2c: removed work arounds in i2c driver for Zynq
Ultrascale+ MPSoC").
The commit aea37006e1 ("dt-bindings: i2c: cadence: Migrate i2c-cadence
documentation to YAML") has converted binding to yaml and the following
issues is reported:
...: i2c@ff030000: compatible: Additional items are not allowed
('cdns,i2c-r1p10' was unexpected)
From schema:
.../Documentation/devicetree/bindings/i2c/cdns,i2c-r1p10.yaml fds
...: i2c@ff030000: compatible: ['cdns,i2c-r1p14', 'cdns,i2c-r1p10'] is too
long
The commit c415f9e830 ("ARM64: zynqmp: Fix i2c node's compatible string")
has added the second compatible string but without removing origin one.
The patch is only keeping one compatible string "cdns,i2c-r1p14".

The idle-states binding documentation[1] mentions that the
'entry-method' property is required on 64-bit platforms and must be
set to "psci".
commit a13f18f59d ("Documentation: arm: Fix typo in the idle-states
bindings examples") attempted to fix this earlier but clearly more is
needed.
Fix the cpu-capacity.txt documentation that uses the incorrect value so
we don't get copy-paste errors like these. Clarify the language in
idle-states.txt by removing the reference to the psci bindings that
might be causing this confusion.
Finally, fix devicetrees of various boards to reflect current
documentation.
