Subject[PATCH v4 REPOST 3/5] ARM: tegra124: Add I2C controller ids to device tree
Date
From: Mikko Perttunen <mperttunen@nvidia.com>

I2C controller ids are required when programming hardware blocks
that send messages to devices connected to an I2C bus, such as
when the PMC sends a poweroff message to the PMIC. Add ids
to all I2C controllers in Tegra124.
