soc: imx: add PM dependency for IMX7_PM_DOMAINS

2017-05-15T01:33:22Z

The new pm domain driver causes a build failure when CONFIG_PM is not set: warning: (IMX7_PM_DOMAINS) selects PM_GENERIC_DOMAINS which has unmet direct dependencies (PM) drivers/base/power/domain_governor.c: In function 'default_suspend_ok': drivers/base/power/domain_governor.c:75:17: error: 'struct dev_pm_info' has no member named 'ignore_children' This adds a dependency to ensure that we don't attempt to build the driver without CONFIG_PM.

soc: imx: Add GPCv2 power gating driver

2017-04-07T11:37:07Z

Add code allowing for control of various power domains managed by GPCv2 IP block found in i.MX7 series of SoCs. Power domains covered by this patch are: - PCIE PHY - MIPI PHY - USB HSIC PHY - USB OTG1/2 PHY Support for any other power domain controlled by GPC is not present, and can be added at some later point. Testing of this code was done against a PCIe driver.
