Felipe Balbi 2f36ff6915 usb: phy: generic: allow multiples calls to usb_phy_generic_register()
it's now very easy to return a platform_device pointer
and have the caller pass it as argument when calling
usb_phy_generic_unregister().

Felipe Balbi d7078df6be 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.

Felipe Balbi 4525beeb9a 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.

Felipe Balbi 0700faaf73 usb: gadget: only GPL drivers in the gadget and phy framework
We only support GPL drivers in the USB Gadget Framework,
it sounds correct to make all exported symbols GPL too.

Neil Zhang 31e322272d usb: phy: initialize the notifier when add a new phy
We need to initialize the notifer before use it.

So lets initialize it when add a new phy device to
reduce the code redundancy.

Wei Yongjun e8d68f88bc usb: phy: phy-generic: fix return value check in usb_nop_xceiv_register()
In case of error, the function platform_device_register_simple() returns
ERR_PTR() and never returns NULL. The NULL test in the return value check
should be replaced with IS_ERR().

Aaro Koskinen dc52c57411 usb: phy-generic: fix nop xceiv probe
Commit bd27fa44e1 (usb: phy: generic:
Don't use regulator framework for RESET line) introduced regression: All
users of usb_nop_xceiv_register() will fail because there is no platform
data and the default reset GPIO is 0 which is a valid GPIO. Fix that.

Felipe Balbi af9f51c551 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.

Michal Nazarewicz 39189c98d1 usb: phy: remove dead code
Commit [4d175f34: usb: phy: nop: Defer clock prepare until PHY init]
removed a goto reaching behind a “return ret” at the end of the function
thus removing the only possible way that statement could be reached, and
so rendering it a dead code.  This commit cleans it up by removing said
dead code.

Roger Quadros bd27fa44e1 usb: phy: generic: Don't use regulator framework for RESET line
Modelling the RESET line as a regulator supply wasn't a good idea
as it kind of abuses the regulator framework and also makes adaptation
code more complex.

Instead, manage the RESET gpio line directly in the driver. Update
the device tree binding information.

This also makes us easy to migrate to a dedicated GPIO RESET controller
whenever it becomes available.

Mark Brown 4d175f340c usb: phy: nop: Defer clock prepare until PHY init
Since we only enable the PHY clock on init and the PHY init and shutdown
does not occur in atomitc context there is no need to prepare the clock
before it is enabled.  Move the clk_prepare() operations to go along
with the enables, allowing the clock to be fully idle when not in use.

Sebastian Andrzej Siewior 3fa4d7344b usb: phy: rename nop_usb_xceiv => usb_phy_gen_xceiv
The "nop" driver isn't a do-nothing-stub but supports a couple functions
like clock on/off or is able to use a voltage regulator. This patch
simply renames the driver to "generic" since it is easy possible to
extend it by a simple function istead of writing a complete driver.
