usb: phy: phy-generic: export init functions This patch exports the mostly generic functions so they can be used from other phy driver instead of duplicating the code. Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Felipe Balbi <balbi@ti.com>

usb: phy: rename <linux/usb/usb_phy_gen_xceiv.h> to <linux/usb/usb_phy_generic.h> now that all functions match the driver name, the only missing piece is to rename the header file itself. Signed-off-by: Felipe Balbi <balbi@ti.com>

usb: phy: generic: migrate to gpio_desc Change internal gpio handling from integer gpios into gpio descriptors. This change only addresses the internal API and device-tree/ACPI, while the legacy platform data remains integer space based. This change is only build compile tested, and very prone to error. I leave this comment for now in the commit message so that this patch gets some testing as I'm pretty sure it's buggy.

usb: phy: generic: add vbus support Add support for vbus detection and power supply. This code is more or less stolen from phy-gpio-vbus-usb.c, and aims at providing a detection mechanism for VBus (ie. usb cable plug) based on a GPIO line, and a power supply activation which draws current from the VBus.

#include <linux/regulator/consumer.h>
usb: phy: generic: fix how we find out about our resources instead of having each user of generic phy find out about its own resources and pass it to the core layer, have th core layer itself figure that out. It's as simple as moving a piece of code around. This fixes a big regression caused during the merge window where am335x-based platforms wouldn't be able to probe their PHY driver.

usb: phy: rename usb_nop_xceiv to usb_phy_generic no functional changes, just renaming the function in order to make it slightly clearer what it should be used for, also matching the driver name. Signed-off-by: Felipe Balbi <balbi@ti.com>
