[PATCH 7/9] spi: core: Convert to dev_pm_domain_attach|detach()

From: Ulf Hansson <hidden>
Date: 2014-08-26 12:07:15
Also in: linux-acpi, linux-devicetree, linux-pm, linux-spi
Subsystem: spi subsystem, the rest · Maintainers: Mark Brown, Linus Torvalds

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

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