-
-Some platforms have a PHY hooked up to the
-SATA controller. The PHY needs to be initialized
-and powered up for SATA to work. We do that

-Subject: [PATCH] ata: ahci_platform: runtime resume the device before use
-
-On OMAP platforms the device needs to be runtime resumed before
-it can be accessed. The OMAP HWMOD framework takes care of
-enabling the module and its resources based on the
-device's runtime PM state.
-
-In this patch we runtime resume during .probe() and runtime suspend
-after .remove().
-
-We also update the runtime PM state during .resume().

-
-ahci_sunxi_phy_init is called from the probe and resume code paths, and
-sleeping is safe in both, so use msleep instead of mdelay.
