Here's the set of driver core patches for 3.19-rc1.

Other than that, a few minor driver core and debugfs changes. There are

commit e47d925 (usb: move the OTG state from
the USB PHY to the OTG structure) moved the
OTG state from struct usb_phy to struct usb_otg.
Unfortunately, even though I fixed quite a few
build regressions with that patch already, this
one was still missing.
Note that this driver still has other randconfig
build problems which I'll leave for driver author
to fix, as that's less trivial.

Before using the PHY framework instead of the USB PHY one, we need to

USB PHY isn't used. This patch moves the OTG state into the OTG
structure, and makes all the needed modifications in the drivers
using the OTG state.

Surprisingly enough, while a big set of patches, the majority is
composed of cleanups (using devm_*, fixing sparse errors, moving
code around, adding const, etc).
The highlights are addition of new support for PLX USB338x devices,
and support for USB 2.0-only configurations of the DWC3 IP core.

Use SIMPLE_DEV_PM_OPS macro and remove DEV_PM_OPS macro, in order
to make the code simpler.

tegra_usb_phy_close() is supposed to undo the effects of
tegra_usb_phy_init(). It is also currently added as the USB PHY shutdown
callback, which is wrong, since tegra_usb_phy_init() is only called
during probing wheras the shutdown callback can get called multiple
times. This then leads to warnings about unbalanced regulator_disable if
the EHCI driver is unbound and bound again at runtime.

Use case is when the phy is configured in host mode and a usb device is
attached to board before bootup. On bootup, with the existing code and
runtime pm enabled, the driver would decrement the pm usage count
without checking the current state of the phy. This pm usage count
decrement would trigger the runtime pm which than would abort the
usb enumeration which was in progress. In my case a usb stick gets
detected and then immediatly the driver goes to low power mode which is
not correct.

This issue was detected on IFC6410 board.
This patch fixes the intial runtime pm trigger by checking the phy
state and decrementing the pm use count only when the phy state is IDLE.

The various devm_ functions allocate memory that is released when a
driver detaches. This patch uses devm_kzalloc, devm_request_irq,
devm_gpio_request, devm_regulator_get etc. for data that is
allocated in the probe function of a platform device and is only
freed in the remove function. The corresponding free functions are
removed and the labels are done away with.
