2015-05-12phy: phy-rcar-gen2: Fix USBHS_UGSTS_LOCK valueYoshihiro Shimoda1-2/+2
According to the technical update (No. TN-RCS-B011A/E), the UGSTS LOCK bit location is bit 8, not bits 1 and 0. It also says that the register address offset of UGSTS is 0x88, not 0x90. So, this patch fixes the USBHS_UGSTS_LOCK value and some comments. Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>

2015-05-12phy: fix Kconfig dependenciesFelipe Balbi1-2/+6
DM816x PHY uses usb_phy_* methods and because of that, it must select USB_PHY, however, because the drivers in question (DM816x, TWL4030 and OMAP_USB2) sit outside of drivers/usb/ directory, meaning they can be built even if USB_SUPPORT=n. This patches fixes the dependencies by adding USB_SUPPORT as a dependency and making all drivers select USB_PHY (which cannot be selected through menuconfig). Note that this fixes some linking breakages when building with randconfig.
