The mt6358 driver was merged in error, it depends on an existing MFD
rather than a newly added one and needs updates to that driver. Disable
the build until those are merged.

The MT6358 is a regulator found on boards based on MediaTek MT8183 and
probably other SoCs. It is a so called pmic and connects as a slave to
SoC using SPI, wrapped inside the pmic-wrapper.

During reset the VMMC regulator doesn't reach 0V and only drops to
1.8V, furthermore the pulse width is under 200us whereas the SD
specification expect 1ms.
The WR_S bit allows the TWL6030 to no reset at all the VMMC during warm
reset and keep the current voltage. Thanks to this workaround the SD
card doesn't reach a undefined reset stage.
Actually this behavior is available for all the LDO regulator, so the
driver will also allow to use it with any of these regulator.

For this 2 reasons being able to no reset at all the VMMC during warm

According to the datasheet http://www.ti.com/lit/ds/symlink/lm36274.pdf:
Table 23. VPOS Bias Register Field Descriptions VPOS[5:0]:
VPOS voltage (50-mV steps): VPOS = 4 V + (Code × 50 mV), 6.5 V max
000000 = 4 V
000001 = 4.05 V
:
011110 = 5.5 V (Default)
:
110010 = 6.5 V
110011 to 111111 map to 6.5 V
So the LM36274_LDO_VSEL_MAX should be 0b110010 (0x32).
The valid selectors are 0 ... LM36274_LDO_VSEL_MAX, n_voltages should be
LM36274_LDO_VSEL_MAX + 1. Similarly, the n_voltages should be
LM36274_BOOST_VSEL_MAX + 1 for LM36274_BOOST.

Now that examples are validated against the DT schema, a typo in
avia-hx711 example generates a warning:
Documentation/devicetree/bindings/iio/adc/avia-hx711.example.dt.yaml: weight: 'avdd-supply' is a required property
Fix the typo.

The schema examples are now validated against the schema itself. The
AST2500 pinctrl schema has a couple of errors:
Documentation/devicetree/bindings/pinctrl/aspeed,ast2500-pinctrl.example.dt.yaml: \
example-0: $nodename:0: 'example-0' does not match '^(bus|soc|axi|ahb|apb)(@[0-9a-f]+)?$'
Documentation/devicetree/bindings/pinctrl/aspeed,ast2500-pinctrl.example.dt.yaml: \
pinctrl: aspeed,external-nodes: [[1, 2]] is too short

The Aspeed pinctl schema have errors in the 'compatible' schema:
Documentation/devicetree/bindings/pinctrl/aspeed,ast2400-pinctrl.yaml: \
properties:compatible:enum: ['aspeed', 'ast2400-pinctrl', 'aspeed', 'g4-pinctrl'] has non-unique elements
Documentation/devicetree/bindings/pinctrl/aspeed,ast2500-pinctrl.yaml: \
properties:compatible:enum: ['aspeed', 'ast2500-pinctrl', 'aspeed', 'g5-pinctrl'] has non-unique elements
Flow style sequences have to be quoted if the vales contain ','. Fix
this by using the more common one line per entry formatting.

Matching on the 'cpus' node was a bad choice because the schema is
incorrectly applied to non-RiscV cpus nodes. As we now have a common cpus
schema which checks the general structure, it is also redundant to do so
in the Risc-V CPU schema.
The downside is one could conceivably mix different architecture's cpu
nodes or have typos in the compatible string. The latter problem pretty
much exists for every schema.

Properties which are child node definitions need to have an explict
type. Otherwise, a matching (DT) property can silently match when an
error is desired. Fix this up tree-wide. Once this is fixed, the
meta-schema will enforce this on any child node definitions.
