[PATCH 0/5] Arm VExpress/Juno motherboard bus clean-ups

[PATCH 0/5] Arm VExpress/Juno motherboard bus clean-ups

[Rob Herring]

I noticed we once again have warnings on VExpress/Juno bus nodes as the
simple-bus schema now expects child nodes to have a unit-address.
Digging into this I noticed the arm,vexpress-juno.yaml schema is out of
date and missing some properties (some of which are unused). I found the
'ranges' handling to be odd as well. This series fixes all those issues.

[PATCH 1/5] dt-bindings: arm,vexpress-juno: Fix 'motherboard' node name

[Rob Herring]

Commit 9d0a36ddcc52 ("arm64: dts: fvp/juno: Fix bus node names") changed
'motherboard' to 'motherboard-bus', but didn't update the schema. In the
mean time, the simple-bus schema started requiring child nodes to have a
unit-address. Update the schema to address both of these issues.

[PATCH 3/5] arm: dts: vexpress: Drop unused properties from motherboard node

[Rob Herring]

Drop the '#interrupt-cells' property in the motherboard node which has no
effect as the node is neither an interrupt-controller or interrupt-map
(that's in the parent node).

Drop 'model' as it is not used by software nor documented.

Drop 'arm,v2m-memory-map' as it is not used by software. The purpose was
to describe which memory map, but that's all described by the DT
already.

[PATCH 5/5] arm: dts: vexpress: Fix addressing issues with 'motherboard-bus' nodes

[Rob Herring]

The 'motherboard-bus' node in Arm Ltd boards fails schema checks as
'simple-bus' child nodes must have a unit-address. The 'ranges' handling is
also wrong (or at least strange) as the mapping of SMC chip selects should
be in the 'arm,vexpress,v2m-p1' node rather than a generic 'simple-bus'
node. Either there's 1 too many levels of 'simple-bus' nodes or 'ranges'
should be moved down a level. The latter change is more simple, so let's do
that. As the 'ranges' value doesn't vary for a given motherboard instance,
we can move 'ranges' into the motherboard dtsi files.

[PATCH 5/5] arm: dts: vexpress: Fix addressing issues with 'motherboard-bus' nodes

[Rob Herring]

The 'motherboard-bus' node in Arm Ltd boards fails schema checks as
'simple-bus' child nodes must have a unit-address. The 'ranges' handling is
also wrong (or at least strange) as the mapping of SMC chip selects should
be in the 'arm,vexpress,v2m-p1' node rather than a generic 'simple-bus'
node. Either there's 1 too many levels of 'simple-bus' nodes or 'ranges'
should be moved down a level. The latter change is more simple, so let's do
that. As the 'ranges' value doesn't vary for a given motherboard instance,
we can move 'ranges' into the motherboard dtsi files.
