PD#146222: saradc: refactor the driver based on the iio sub-system
the sar adc driver has been moved from directory input/saradc
into directory iio/adc, and is refactored base on the standard
iio sub-system.
the iio sub-system provide two ways to access sar adc resources:
1. standard api for consumer driver
it can be found at the file "include/linux/iio/consumer.h".
2. sysfs interface for user space(X: 0-7)
- obtain 10-bit sample value:
cat sys/bus/iio/devices/iio:device0/in_voltage[X]_input
- obtain raw sample value(10-bit or 12-bit):
cat sys/bus/iio/devices/iio:device0/in_voltage[X]_raw
- obtain mean raw sample value:
cat sys/bus/iio/devices/iio:device0/in_voltage[X]_mean_raw
test pass on the gxl skt, axg skt, m200.

PD#146539: usb: fix adb reboot panic.
Avoid kernel panic caused by race condition. For example,
1. In the ffs_epfile_io function, data buffer is allocated
for non-halt requests and the address of this buffer is
writed to usb controller registers.
2. After adb process be killed, data buffer is freed and
this memory is allocated for the other. But the address
is hold by the controller.
3. Adbd in PC is running. So, the controller receive the
data and write to this memory.
4. The value of this memory is modified by the controller.
This could cause the kernel panic.
To avoid this, during FunctionFS mount, we allocated the
data buffer for requests. And the memory resources has
been released in kill_sb.

in certain cases/system, echo command will refuse to interpret backslash

PD#145741: wifi: bcm: fix unable to enter deep suspend mode issue
for the wowlan (wake on wireless lan) function under Linux platfrom,
we have problem to configure it via wpa_supplicant as we do it at Android
platform. so here when it enter into suspend mode, we try to skip calling
cfg80211_leave_all() function at the wire core path.
since this modify the wifi core code, it will also affect other
wifi drivers (not only bcm wifi).
