Subject[PATCH v16 1/2] dt-binding: i2c: add bus-supply property
Date
From: Bibby Hsieh <bibby.hsieh@mediatek.com>

In some platforms, they disable the power-supply of i2c due
to power consumption reduction. This patch add bus-supply property.

Binding may contain optional "interrupts" property, describing interrupts

interrupt if not using interrupt names) as primary interrupt for the slave.
