Even though the DPI IP has a reset bit on all MediaTek SoCs, it
is optional, and has always been unused until MT8195; specifically:
on older SoCs, like MT8173, the reset bit is located in MMSYS, and
on newer SoCs, like MT8195, it is located in VDOSYS.
For this reason, allow specifying the resets and reset-names on
all MediaTek SoCs.
Those properties are optional because there are multiple ways to
reset this IP and the reset lines in MM/VDO are used only if the
IP cannot perform warm-reset.

In some cases it's reasonable to describe DP lanes and AUX signal lines
separately in the DT. One of the typical reasons is if the source of DP
signals can support either USB-C or DP connections. In such a case the
transmitter of DP signals have separate ports: one for SS lanes and
another one for SBU / AUX signals.
Instead of leaving AUX signals from the controller unconnected, add an
option to the DT schema to AUX signal lines separately from the main
link lanes.

The i.MX6Q Reference Manual describes the three digital LDO regulators
as follows:
"10.4.1.1.1
Digital LDO Regulators
The integrated PMU includes three digital LDO regulators: LDO_ARM, LDO_PU, and
LDO_SOC. These regulators provide power to the ARM_Core power domain, the
combined VPU, IPU and GPU power domain, and the rest of the SoC logic (except
always-ON SNVS domain)."
imx6dl.dtsi uses the correct names to describe these supplies:
arm-supply = <®_arm>;
pu-supply = <®_pu>;
soc-supply = <®_soc>;
'arm-supply' and 'soc-supply' are already documented, but 'pu-supply' is not.
Document the 'pu-supply' property and set it to deprecated.
This fixes the following dt-schema warning:

With the introduction of the of_msi_xlate() function, the OF layer
provides an API to map a device ID and retrieve the MSI controller
node the ID is mapped to with a single call.
of_msi_map_id() is currently used to map a deviceID to a specific
MSI controller node; of_msi_xlate() can be used for that purpose
too, there is no need to keep the two functions.
Convert of_msi_map_id() to of_msi_xlate() calls and update the
of_msi_xlate() documentation to describe how the struct device_node
pointer passed in should be set-up to either provide the MSI controller
node target or receive its pointer upon mapping completion.

Document established Devicetree bindings maintainers review practice:
1. Device node names should not be treated as an ABI, unless for
children of a device when documented.
There were many patches posted using of_find_node_by_name() or
of_node_name_eq() for accessing siblings or completely different
nodes. These cases were introducing undocumented ABI, so they are
discouraged.
2. 'simple-mfd' means children do not depend on parent device resources.
'simple-bus' is so simple, that even 'reg' properties are not
applicable.
