[PATCH 0/3] Fix spear600-smi YAML conversion

[Miquel Raynal]

Recent conversion from txt to yaml of the Spear600 SMI binding by Akhila
lead to warnings. These are my 2cts in getting the yaml conversion done
:-)

Cheers,

[PATCH 1/3] dt-bindings: mtd: st,spear600-smi: Fix description

[Miquel Raynal]

The description mixes two nodes. There is the controller, and there is
the flash. Describe the flash (which itself can be considered an mtd
device, unlike the top level controller), and move the st,smi-fast-mode
property inside, as this property is flash specific and should not live
in the parent controller node.

[PATCH 2/3] dt-bindings: mtd: st,spear600-smi: #address/size-cells is mandatory

[Miquel Raynal]

These properties must be set because they overwrite the default values,
especially #size-cells which is 0 for most controllers and is 'const: 1'
here.

Example is wrong, the reg property of the flash is always matching the
node name.
