Tony Lindgren 2ad2af0816 phy: mapphone-mdm6600: Improve phy related runtime PM calls ... I noticed that phy_pm_runtime_get_sync() and phy_pm_runtime_put() are not currently doing anything for phy-mapphone-mdm6600, only the sysfs interface for works for "auto" and "on". This is because of the shared GPIO pins between mdm6600 USB port and n_gsm port. We have not enabled runtime PM for the phy driver until after we've booted up mdm6600 properly to the USB mode. Otherwise phy_create() would have called pm_runtime_enable() and pm_runtime_no_callbacks() automatically on init. Let's fix this by registering the phy a bit later after we've powered up the mdm6600 USB port. And as the PM runtime support is only needed for the n_gsm mode and not for USB, we can allow the device to idle between phy_mdm6600_power_on() and phy_mdm6600_power_off(). Note that for suspend, runtime_pm is already disabled for the phy so we need to check for pm_runtime_enabled().
