[PATCH 0/7] dt-bindings: i2c: few fixes and cleanups

[Krzysztof Kozlowski]

Few fixes for I2C controller schemas. The third patch (atmel,at91sam)
depends on first, so I suggest not splitting this into fixes branch but
take as is via next branch.

Best regards,
Krzysztof

[PATCH 3/7] dt-bindings: i2c: atmel,at91sam: drop unneeded address/size-cells

[Krzysztof Kozlowski]

The reference i2c-controller.yaml already defines 'address-cells' and
'size-cells', so drop them from list of properties.  Drop them as well
from required properties, even though i2c-controller.yaml does not
require them, because I2C controller could be enabled without any
children in DTS for user-space usage.

[PATCH 7/7] dt-bindings: i2c: adjust indentation in DTS example to coding style

[Krzysztof Kozlowski]

Bindings coding style expects 2- or 4-space indentation in the DTS
example.  Correct files having something odd (6- or 8-space) to 4-space
while re-ordering few properties according to DTS coding style (the
first property should be compatible, then reg/ranges).  No functional
impact.

So you broke the binding... Why openly ignoring my first sentence?
