usb: xceiv: create nop-usb-xceiv.h and avoid pollution on otg.h nop-usb-xceiv was polluting otg.h with its own function prototypes. Move those prototypes to a nop-usb-xceiv.h header. Signed-off-by: Felipe Balbi <balbi@ti.com>

usb: phy: nop: Add some parameters to platform data Add clk_rate parameter to platform data. If supplied, the NOP phy driver will program the clock to that rate during probe. Also add 2 flags, needs_vcc and needs_reset. If the flag is set and the regulator couldn't be found then the driver will bail out with -EPROBE_DEFER.

usb: usb_phy_gen: refine conditional declaration of usb_nop_xceiv_register Commit 3fa4d734 (usb: phy: rename nop_usb_xceiv => usb_phy_gen_xceiv) changed the conditional around the declaration of usb_nop_xceiv_register from #if defined(CONFIG_NOP_USB_XCEIV) || (defined(CONFIG_NOP_USB_XCEIV_MODULE) && defined(MODULE)) to #if IS_ENABLED(CONFIG_NOP_USB_XCEIV) While that looks the same, it is semantically different. The first expression is true if CONFIG_NOP_USB_XCEIV is built as module and if the including code is built as module. The second expression is true if code depending on CONFIG_NOP_USB_XCEIV if built as module or into the kernel. As a result, the arm:allmodconfig build fails with arch/arm/mach-omap2/built-in.o: In function `omap3_evm_init': arch/arm/mach-omap2/board-omap3evm.c:703: undefined reference to `usb_nop_xceiv_register' Fix the problem by reverting to the old conditional.
