this method will be used to enable or disable
the charge pump.Whenever we have DRD devices, we need to be
able to turn VBUS on or off whenever we want.Note that in the ideal case, this would be
controlled by the ID-pin Interrupt, but not
all devices have ID-pin properly routed since
manufacturers can choose to save that trace
if they're building a host-only product out
of a DRD IP.This is also useful during debugging where
we might not have the proper cable hanging
around.Signed-off-by: Felipe Balbi

We already have a considerable amount of USB
PHY drivers, making it a menuconfig just
prevents us from adding too much churn to
USB's menuconfig.While at that, also select USB_OTG_UTILS from
this new menuconfig just to keep backwards
compatibility until we manage to remove
that symbol.Signed-off-by: Felipe Balbi

We don't need the ->register_my_device flag

Signed-off-by: Felipe Balbi
-
Currently all UDC drivers are calling
device_register() before calling
usb_add_gadget_udc(). In order to avoid
code duplication, we can allow udc-core.c
register that device.However that would become a really large patch,
so to cope with the meanwhile and allow us
to write bite-sized patches, we're adding
a flag which will be set by UDC driver once
it removes the code for registering the
gadget device.Once all are converted, the new flag will
be removed.Reviewed-by: Tomasz Figa

Pull OpenRISC bug fixes from Jonas Bonn:
- The GPIO descriptor work has exposed how broken the non-GPIOLIB bits
for OpenRISC were. We now require GPIOLIB as this is the preferred
way forward.- The system.h split introduced a bug in llist.h for arches using
asm-generic/cmpxchg.h directly, which is currently only OpenRISC.
The patch here moves two defines from asm-generic/atomic.h to
asm-generic/cmpxchg.h to make things work as they should.- The VIRT_TO_BUS selector was added for OpenRISC, but OpenRISC does
not have the virt_to_bus methods, so there's a patch to remove it
again.* tag 'for-3.9-rc3' of git://openrisc.net/jonas/linux:

This patch fixes a kernel crash when using precise sampling (PEBS)
after a suspend/resume. Turns out the CPU notifier code is not invoked
on CPU0 (BP). Therefore, the DS_AREA (used by PEBS) is not restored properly
by the kernel and keeps it power-on/resume value of 0 causing any PEBS
measurement to crash when running on CPU0.The workaround is to add a hook in the actual resume code to restore
the DS Area MSR value. It is invoked for all CPUS. So for all but CPU0,
the DS_AREA will be restored twice but this is harmless.Reported-by: Linus Torvalds

Pull fix for hlist_entry_safe() regression from Paul McKenney:
"This contains a single commit that fixes a regression in
hlist_entry_safe(). This macro references its argument twice, which
can cause NULL-pointer errors. This commit applies a gcc statement
expression, creating a temporary variable to avoid the double
reference. This has been posted to LKML athttps://lkml.org/lkml/2013/3/9/75.
Kudos to CAI Qian, whose testing uncovered this, to Eric Dumazet, who
spotted root cause, and to Li Zefan, who tested this commit."* 'rcu/urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu:
list: Fix double fetch of pointer in hlist_entry_safe() -
The current version of hlist_entry_safe() fetches the pointer twice,
once to test for NULL and the other to compute the offset back to the
enclosing structure. This is OK for normal lock-based use because in
that case, the pointer cannot change. However, when the pointer is
protected by RCU (as in "rcu_dereference(p)"), then the pointer can
change at any time. This use case can result in the following sequence
of events:1. CPU 0 invokes hlist_entry_safe(), fetches the RCU-protected
pointer as sees that it is non-NULL.2. CPU 1 invokes hlist_del_rcu(), deleting the entry that CPU 0
just fetched a pointer to. Because this is the last entry
in the list, the pointer fetched by CPU 0 is now NULL.3. CPU 0 refetches the pointer, obtains NULL, and then gets a
NULL-pointer crash.This commit therefore applies gcc's "({ })" statement expression to
create a temporary variable so that the specified pointer is fetched
only once, avoiding the above sequence of events. Please note that
it is the caller's responsibility to use rcu_dereference() as needed.
This allows RCU-protected uses to work correctly without imposing
any additional overhead on the non-RCU case.Many thanks to Eric Dumazet for spotting root cause!

include/linux/res_counter.h needs errno.h -
In the UAPI header files, __BIG_ENDIAN and __LITTLE_ENDIAN must be
compared against __BYTE_ORDER in preprocessor conditionals where these are
exposed to userspace (that is they're not inside __KERNEL__ conditionals).However, in the main kernel the norm is to check for
"defined(__XXX_ENDIAN)" rather than comparing against __BYTE_ORDER and
this has incorrectly leaked into the userspace headers.The definition of struct mdp_superblock_s in linux/raid/md_p.h is wrong in
this way. Note that userspace will likely interpret the ordering of the
fields incorrectly as the big-endian variant on a little-endian machines -
depending on header inclusion order.[!!!] NOTE [!!!] This patch may adversely change the userspace API. It might
be better to fix the ordering of events_hi, events_lo, cp_events_hi and

This same driver can be used by atmel based touchscreens and touchpads
(buttonpads). Platform data may specify a device is a touchpad
using the is_tp flag.This will cause the driver to perform some touchpad specific
initializations, such as:
* register input device name "Atmel maXTouch Touchpad" instead of
Touchscreen.
* register BTN_LEFT & BTN_TOOL_* event types.
* register axis resolution (as a fixed constant, for now)
* register BUTTONPAD property
* process GPIO buttons using reportid T19Input event GPIO mapping is done by the platform data key_map array.
key_map[x] should contain the KEY or BTN code to send when processing
GPIOx from T19. To specify a GPIO as not an input source, populate
with KEY_RESERVED, or 0.Signed-off-by: Daniel Kurtz
