Changes from v7: - Rebased on 'xceive' of Balbi's usb tree. - Placing proper Acked By's received for each patch.
Changes from v6: - Changing macro names from 'HOST_CTRL0_FSEL_CLKSEL_XX' to 'FSEL_CLKSEL_XX' since it's being used by HOST and OTG block to prepare reference clock. - Directly Assigning 'FSEL_CLKSEL_XX' to refclk_freq in samsung_usbphy_get_refclk_freq() instead of ORing them since we are anyways using macros: "HOST_CTRL0_FSEL(_x) ((_x) << 16)" "OTG_SYS_FSEL(_x) ((_x) << 4)"
Changes from v5: - Adding hostphy enable mask and hostphy register offsets to driver data in order to access the HOSTPHY CONTROL register.
- Adding member 'otg' to struct samsung-usbphy so that its consumers can call otg->set_host so as to make 'phy' aware of the consumer type: HOST/DEVICE
- Adding 'otg' to 'struct s5p_ehci_hcd' and 'struct exynos_ohci_hcd' which keeps track of 'otg' of the controllers' phy. This then sets the host.
- Moved samsung_usbphy_set_type() calls from ehci-s5p and ohci-exynos to phy driver itself where based on phy_type it is called.
- Added separate macro definition for USB20PHY_CFG register to select between host/device type usb link.
- Removing unnecessary argument 'phy_type' from samsung_usbphy_set_type() and samsung_usbphy_cfg_sel().
- Addressed few nits: -- added macro for 'KHZ' -- removing useless 'if' from samsung_usbphy_cfg_sel() -- keeping the place of clk_get intact and requesting driver data before that.
