The Ralink MIPS platform does not use Common Clock Framework and does
not define certain clock operations leading to compile test failures:

/usr/bin/mips-linux-gnu-ld: drivers/usb/phy/phy-tegra-usb.o: in function `tegra_usb_phy_init':
phy-tegra-usb.c:(.text+0x1dd4): undefined reference to `clk_get_parent'
