5719b81988 acer-wmi: No wifi rfkill on Sony machines
The wireless rfkill should charged by sony-laptop but not acer-wmi.
So, add Sony's SNY5001 acpi device to blacklist in acer-wmi.

6e0044bedc asus-wmi: store backlight power status for AIO machine
Due to some implementation reasons, ASUS ET2012 All-in-One machines
can't report the correct backlight power status, it will always return
1. To track the backlight power status correctly, we have to store the
status by ourselves.

BTW, by the BIOS design, the backlight power will be turn on/off
sequently, no matter what the value of the parameter will be.
More over, the brightness adjustment command will turn on the backlight
power. Those behaviors will make us fail to track the backlight power
status.
For example, While we are trying to turn on the backlight power,
we will send out the brightness adjustment command and then trying to
figure out if we have to turn on the backlight power, then send out
the command. But, the real case is that, the backlight power turns on
while sending the brightness adjustment command, and then we send out
the command to turn on the backlight power, it actually will turn off
the backlight power and the backlight power status we recorded becomes
wrong. So, we have to seperate these two commands by a if statement.

c87992d1fa asus-wmi: add scalar board brightness adj. support
Some ASUS ET2012E/I All-in-One machines that use a scalar board
to control the brightness, and they only accept brightness up and down
command. So, I introduced a get_scalar_command() function to pass the
command to the scalar board through WMI.

Besides, we have to store the brightness value locally, for we need the
old value to know the brightness value is increasing or decreasing.

BTW, since there is no way to retrieve the actual brightness(it would be
a fixed value), and the max brightness value would be fixed to 1, so we
have to keep passing the brightness up/down command when we reached the
max brightness value or 0.

13151631b5 ab8500-fg: A8500 fuel gauge driver
This driver is responsible for provide battery parameters to user space via
sysfs by registers to power supply class. It uses fuel gauge and gpadc driver
in obtaining the battery parameters. These battery properties are used by
abx500 charging algorithm driver to monitor the battery.

84edbeeab6 ab8500-charger: AB8500 charger driver
This driver is responsible for detecting the ac/usb plugin and also includes
function to enable ac/usb charging and re-kick the watchdog.
It registers with the power supply class and provides information to the user
space. The information include status of ac/usb charger device.
This information in turn will be used by the abx500 charging algorithm driver
to enable/disable and monitor charging.
