The twl4030 usb phy needs to be active while we are using
the USB VBUS as a current source for charging.
In particular, the usb3v1 regulator must be enabled and the
PHY_PWR_PHYPWD bit must be set to keep the phy powered.

These patches make a number of improvements to twl4030_charger.
So are just internal cleanups (e.g. use of devres). Others allow
better control of charging through both manual and automatic means.
- the maximum current can be configured via sysfs.
- the charger will only draw that current if it

twl4030_charger currently finds the associated phy
using usb_get_phy() which will return the first USB2 phy.
If your platform has multiple such phys (as mine does),
this is not reliable (and reliably fails on the GTA04).

The twl4030_charger is physically paired with the twl4030 USB phy,
so the drivers need to be able to reliably find each other.
twl4030_charger currently uses usb_get_phy(), which works if there is
only one phy to choose from, but is not reliable in more complex
configurations.
These patches add a
Split the "get phy from device_node" functionality out of
"get phy by phandle" so it can be used directly.
This is useful when a battery-charger is intimately associated with a
particular phy but handled by a separate driver. The charger
can find the device_node based on sibling relationships

Those two weeks were during the merge window, so I wasn't queueing

The twl4030 phy can measure, with low precision, the
resistance-to-ground of the ID pin.
Add a function to read the value, and export the result
via sysfs.
If the read fails, which it does sometimes, try again in 50msec.

If an 'A' plug is inserted, ID should be pulled to ground.
If a 'B' plug, then ID should be floating.
If an Accessory Charger Adapter is inserted, then ID will
be neither grounded nor floating. In this case tell the
USB subsystem that it is an A plug, and the battery
charging subsystem that it is
The charger needs to know when a USB gadget has been enumerated
and what the agreed maximum current was so that it can adjust
charging accordingly.
So define a "set_power()" function to record the permitted
draw, and pass a pointer to that when sending USB_EVENT_ENUMERATED
notification.

Hi,
the following 4 patches make some improvements to the twl4030
phy. Together with some other patches I have for twl4030_charger,
they allow for better automatic control of charging.
In particular, the status of the ID pin is assessed and the
result in communicated to the charger drivers.
A construct like:
if (pm_runtime_suspended(twl->dev))
pm_runtime_get_sync(twl->dev);
is against the spirit of the runtime_pm interface as it
makes the internal refcounting useless.
In this case it is also racy, particularly as 'put_autosuspend'
is use to drop a reference.

Many architectures have their own oops locking code that allows
the lock to be taken recursively. Create a common version.
Avoid creating generic locking functions, so they can't be
abused in other parts of the kernel.
