cpufreq: Add boost frequency support in core
This commit adds boost frequency support in cpufreq core (Hardware &
Software).
Some SoC (like Exynos4 - e.g. 4x12) allow setting frequency above
its normal operation limits. Such a mode shall be only used for a short
time.
Overclocking (boost) support is essentially provided by platform
dependent cpufreq driver.
This commit unifies support for SW and HW (Intel) overclocking solutions
in the core cpufreq driver. Previously the "boost" sysfs attribute was
defined at acpi driver code.
By default boost is disabled. One global attribute is available at:
/sys/devices/system/cpu/cpufreq/boost.
It only shows up when cpufreq driver supports overclocking.
Under the hood frequencies dedicated for boosting are marked with a
special flag (CPUFREQ_BOOST_FREQ) at driver's frequency table.
It is the user's concern to enable/disable overclocking with proper call to
sysfs.

regulator:max77686: Correct GPIOs for BUCK2 DVS setting
Before this patch SELB and DVS pins were wrongly defined in the DTS.
As a result MAX77686 always used BUCK2_DVS1 register (the DVS pins were
set all to 0). However the default DVS index (default_dvs_idx) was set to 1.
Therefore, the default value of BUCK2_DVS1 register (1.1V) was always
setup. Wrongly the driver was changing BUCK2_DVS2 register. Due to that
voltage was NOT changed at all.
The problem appeared when BOOST was ported to v3.10-mobile. It requires
around 1.3V, but default voltage is set to 1.1V (0x28). Too small voltage
resulted in OOPs at random places.
As a side note:
The MAX77686 is NOT using DVS with GPIO. It changes the value of current
voltage with I2C utilization.

usb:gadget: Refcount for gadget pullup
This commit fixes the way gadget's pullup method (wrapped at
usb_gadget_connect/disconnect) is called in the udc-core.
The composite driver allows correct driver registration, even when it calls
the usb_gadget_disconnect method (composite driver configuration is defered
for user space - please look into the description of usb_composite_probe at
composite.c - line: 1623)
One such example is the CCG (Configurable Composite Gadget) driver (at
drivers/staging/ccg), which after its registration has no usb descriptor
(i.e. idProduct, idVendor etc.) and functions registered. Those are configured
after writing to /sys/module/g_ccg/parameters/ or /sys/class/ccg_usb/ccg0/.
Unfortunately, the code at 'usb_gadget_probe_driver' method (some code omitted):
if (udc_is_newstyle(udc)) {
bind(udc->gadget);
usb_gadget_udc_start(udc->gadget, driver);
usb_gadget_connect(udc->gadget);
}
Explicitly calls the usb_gadget_connect method for this driver. It looks like
the udc-core enables pullup for a driver, which has no functions and no
descriptor filled (those values are feed from userspace).
The USB composite driver API allows correct driver registration with calling
usb_gadget_disconnect method, but as it is now, _ALL_ newstyle usb gadgets are
connected by default. Therefore it violates the composite API.
The solution (at least until the udc-core is reworked) is to add atomic
variable, which helps in balancing the number of called usb_gadget_connect/
disconnect functions.
