[PATCH v3 5/9] i2c: core: Convert to dev_pm_domain_attach|detach()

From: Ulf Hansson <hidden>
Date: 2014-09-04 13:52:32
Also in: linux-acpi, linux-arm-kernel, linux-i2c, linux-pm
Subsystem: i2c subsystem, the rest · Maintainers: Wolfram Sang, Linus Torvalds

Previously only the ACPI PM domain was supported by the i2c bus.

Let's convert to the common attach/detach functions for PM domains,
which currently means we are extending the support to include the
generic PM domain as well.
