2014-03-09phy: ti-pipe3: Fix suspend/resume and module reloadRoger Quadros
Due to Errata i783, SATA breaks if its DPLL is idled. The recommeded workaround to issue a softreset to the SATA controller doesn't seem to work. Here we just prevent SATA DPLL from Idling and hence avoid the issue altogether. Signed-off-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
2014-03-09phy: ti-pipe3: streamline PHY operationsRoger Quadros
Limit .power_on() and .power_off() to just control the PHY power and not the DPLL. The DPLL will be enabled in .init() and idled in .exit(). Don't reprogram the DPLL if it has been already locked by the bootloader. This fixes a problem with SATA, where it fails if SATA was used by the bootloader.

2014-03-09phy: ti-pipe3: Don't get 'wkupclk' and 'refclk' for SATA PHYRoger Quadros
SATA PHY doesn't need 'wkupclk; and 'refclk' so don't try to get them for SATA PHY. Signed-off-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
2014-03-09phy: ti-pipe3: Add SATA DPLL supportRoger Quadros
USB and SATA DPLLs need different settings. Provide the SATA DPLL settings and use the proper DPLL settings based on device tree node's compatible_id. Signed-off-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
2014-03-09phy: ti-pipe3: cleanup clock handlingRoger Quadros
As this driver is no longer USB specific, use generic clock names. - Fix PLL_SD_SHIFT from 9 to 10 - Don't separate prepare/unprepare clock from enable/disable. This ensures optimal power savings. Signed-off-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
2014-03-09phy: rename struct omap_control_usb to struct omap_control_phyKishon Vijay Abraham I
Rename struct omap_control_usb to struct omap_control_phy since it can be used to control PHY of USB, SATA and PCIE. Also move the driver and include files under *phy* and made the corresponding changes in the users of phy-omap-control.

2014-03-06drivers: phy: usb3/pipe3: Adapt pipe3 driver to Generic PHY FrameworkKishon Vijay Abraham I
Adapted omap-usb3 PHY driver to Generic PHY Framework and moved phy-omap-usb3 driver in drivers/usb/phy to drivers/phy and also renamed the file to phy-ti-pipe3 since this same driver will be used for SATA PHY and PCIE PHY. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
